All notable changes to Combo's Tweaks. Support: nikvol1978@gmail.com

[1.0.5] – 2026-10-06

Widgets is left to Windows where Windows protects it, and an open Widgets entry clears by itself.

Widgets and Windows' protection

• Where Windows protects the Widgets setting, Combo's Tweaks no longer tries to change it. On most up-to-date PCs, Windows' UserChoice Protection Driver refuses the Widgets policy, and the taskbar's Widgets button, to every app that isn't Windows' own, even as administrator. In 1.0.3 and 1.0.4 that showed as "Not changed: Widgets off."
• The Widgets off card now says "Windows doesn't let apps change this. Turn it off in Taskbar settings." with an Open Taskbar settings button, and says so once the button is off. On Windows 10 it says how to turn off News and interests from the taskbar.
• On a PC where the driver doesn't run, Widgets off works as before.
• Undo of an older Widgets off change still works. If Windows refuses it, the result says how to undo it in the Group Policy Editor.

Quick Optimise

• Quick Optimise shows a Widgets button row with Open Taskbar settings, instead of a Widgets off switch. Cleaner Windows no longer includes Widgets off there. The row shows "On" once the button is off, and it's never counted as a change or a new recommendation.

Fixes

• An open Widgets off entry left by an earlier version closes by itself when 1.0.5 starts. Windows had refused the change and then refused putting it back, although nothing had changed, so it showed under Needs attention. 1.0.5 checks that the value wasn't there before and isn't there now, closes the entry without changing anything on your PC, and notes it in the log.

[1.0.4] – 2026-10-05

Home shows what Quick Optimise did, and a change Windows refuses no longer stops a run.

Quick Optimise on Home

• Home now shows whether Quick Optimise has run, on a card under the stat chips. Before the first run it says "Not optimised yet" with its Quick Optimise button; after a run, "Optimised on 5 Oct · 24 changes active" with View and Undo all.
• If you undo some of its changes through their cards, the card shows "23 of 24 still active". If Windows changes one back, the card says so once Quick Optimise has checked (when you open it or press View), and Optimise puts it back.
• Undo all on Home is the Done screen's Undo all: one question, then exactly Quick Optimise's changes are put back. The card goes back to "Not optimised yet" and says when your last run was.
• Picks that are new for your PC (after an update, a new plan or new hardware) show as "1 new recommendation", and the card's button opens them. Only picks that are on by default count, not personal choices like the frame cap.
• The page's Quick Optimise button shows a check while its changes are on, and a command-line --apply quick-optimise counts as a run too.
• Starting the app stays light: the card reads a small file saved after each run (quick-optimise.json, beside the backups) and the app's own backups, and checks nothing on your PC.

Coming from 1.0.3

• If you ran Quick Optimise in 1.0.3, Home shows that run straight away instead of "Not optimised yet". 1.0.3 kept no record of its runs, so 1.0.4 reads the last one from the app's log once, with only the changes that are still applied.

Fixes

• A change Windows refuses no longer stops Quick Optimise or a profile part-way. In 1.0.3 a refused setting (seen with Widgets off) was taken for a backup that couldn't be saved, so the tweaks after it weren't applied; now only that tweak fails, it's named on the Done screen, and the rest still apply.
• If a run does stop early (a backup that can't be saved, or Cancel), the Done screen says why.

[1.0.3] – 2026-10-05

Quick Optimise now picks for your PC, on a much shorter screen.

Picked for your PC

• Quick Optimise looks at your PC first and picks only Safe tweaks that suit it, each with a one-line reason. It reads your processor, graphics card, memory, your main monitor's refresh rate, Wi-Fi or a network cable, and whether a hard drive is fitted; "why?" next to each pick says why ("Because you're on Wi-Fi").
• A desktop gets the Ultimate Performance plan; a laptop gets Combo's Laptop plan, quick on the charger and kind to the battery, and none of the desktop-only tweaks. A Ryzen X3D with two CCDs keeps its own power plan and Game Bar, so games stay on the cache cores.
• Network power saving goes off only for the connection you use, hard drives are kept spinning only if you have one, browsers stop running in the background too when memory is 8 GB or less, and NVIDIA crash reports only come up with an NVIDIA card.
• Never a Moderate, High-risk, Extreme, experimental or retired tweak, so Quick Optimise never needs a warning.
• Personal choices are listed but off until you tick them: mouse acceleration, Game DVR, background apps, and a frame cap just under your monitor's refresh rate ("Smoother with G-Sync/FreeSync"; AMD and Intel graphics get the steps instead).
• Less tracking and a cleaner Windows (tips, widgets, ads and suggestions, suggested apps) are one row each, on by default.

A shorter screen

• Quick Optimise opens over Home, with your PC at the top and one line per pick. The picks come in groups (Power, Gaming, Input, Network, Storage, Privacy, Cleaner Windows), each with a switch, then "All backed up · Undo anytime" and one "Optimise my PC" button. It's the preview, so nothing is listed twice; the restore point and the network adapter's question still come.
• Then a short progress, and "Done" with how many changes were made and which need a restart.
• Each pick is checked on its own, within a time limit: one that can't be checked shows "Unknown" and is left as it is, so the screen always appears. While a game runs, the checks wait and the screen says so.

Undo all, and your plan

• Undo all puts back exactly what that Quick Optimise run changed, after one question.
• Your plan is respected: a pick your plan doesn't include shows a small Plus or Premium tag and is never applied.
• The Profiles page's Quick Optimise opens the same screen, in every plan.
• The command line's --dry-run shows each pick and its reason; --apply quick-optimise applies the picks that are on by default.

Fixes

• Data-collection tasks off and NVIDIA crash reports off now treat a scheduled task that isn't on your PC as missing, instead of failing to check it.

[1.0.2] – 2026-10-05

Every card says what it's for, and the settings nobody has measured are kept apart.

Labels that say what a tweak is for

• A tweak that isn't about FPS now shows what it's for instead of "Placebo for most games": Less tracking, Cleaner Windows, Fewer background apps, More disk space, Keeps your settings, Sleep & wake control, Security or Fixes device drop-outs. Its honest note no longer starts with "No FPS change".
• "Unverified gain" is now "Not measured yet", and a network card says "won't lower your ping" once, in its honest note.
• Lowest input delay mode is now called Timer Resolution mode: it holds Windows' timer, nothing more.

Experimental and retired tweaks

• Nine speed settings with no measured gain moved to Advanced › Experimental: hidden until Settings › "Show experimental tweaks" is on, never in a profile, and not counted in the plans' totals (now Free 12, Plus 82 and Premium 100). They keep their plans, and one you turned on always stays visible so you can undo it.
• Four High-risk tweaks with no measured gain are retired: GPU at full speed (P0), HDCP off, GPU MSI mode and Write-cache flushing off. They can't be turned on any more. If you turned one on, it stays on and its card stays visible, and Undo, Undo everything and --revert-all still put it back.
• The licence agreement (EULA.txt, section 2) now says an update may retire a tweak. The welcome screen asks you to accept it once more and says what changed in one line.

Smaller changes

• While a game runs, a card that's waiting for its check says "Paused while you're gaming" instead of "Checking…".
• Ask Combo AI says what a tweak is for ("it's for less tracking, not FPS"), that an experimental one has no measured gain, and that a retired one can only be undone.
• The first-run and About screens say "Results vary by PC and game. Every change is backed up first, and Undo puts it back."

[1.0.1] – 2026-10-05

Your licence key arrives by itself after you buy, and Windows shows the app by its own name.

Your key right after paying

• After checkout, the page you come back to shows your licence key, and still shows it if you open it again later. These keys need Combo's Tweaks 1.0.1 or newer; keys made before keep working.

Plus to Premium

• Upgrade now checks your Plus key on the website first. The Upgrade button (A$10.00) opens the website's upgrade page: it checks your Plus key and the email it was bought with, then opens the checkout with that email, so your Premium key works with the same email. Each Plus licence can be upgraded once.

Smaller changes

• Plus and Premium are sold through Link, by Stripe, and the licence agreement now says so. EULA.txt (sections 1 and 9) says they're sold under the terms shown at checkout and that you can also ask Link support about a refund. The welcome screens ask you to accept it once more.
• Windows shows the exe as CombosTweaks.exe, described as "Combo's Tweaks" (Properties › Details, Task Manager), not as CombosTweaks.dll.
• The support address (Get help, Settings) is shown in a font where 1 and l look different.

[1.0.0] – 2026-10-05

First release. The Buy buttons open Stripe's checkout, and a licence key made with the owner's KeyGen unlocks Plus or Premium; without one the app is Free.

Ask Combo AI

• Ask Combo AI, a new TOOLS page in every plan (Free 1 question a day, Plus 3, Premium 6; Plus and Premium are answered by a bigger model, Llama 3.3 70B): ask about your PC's performance, Windows or your connection, and get a short, honest answer: a yes or no first when you ask about a tweak ("should I use Nagle off for Fortnite?": no, it doesn't help in Fortnite), the likely causes, the app's own tools under To investigate further in their own words (Network › Bufferbloat and Tests for ping spikes, Smart System Detection for memory speed and drivers, the FPS Limiter for a frame cap) and anything outside the app on a line of its own (Task Manager, HWiNFO, your router's settings, your graphics card maker's site), then a Suggested tweaks list the server makes itself: at most 3 of Combo's Tweaks' own tweaks, the most useful first, each with its risk, its impact (Noticeable, Small, Situational or Placebo for most games) and the app's own description, so the AI never says in its own words what a tweak does. Its tweaks fit what you asked (network tweaks for ping, FPS, GPU and power tweaks for stutter, input tweaks for input delay); it never suggests a High or Extreme risk tweak unless you ask about one, a tweak your PC can't use (Wi-Fi tweaks when you're on a network cable, GPU ECC off on a GeForce card) a frame-cap tweak (frame caps are the FPS Limiter's) or a tweak that doesn't help in the game you name (Nagle off for Fortnite, VALORANT, CS2 and other games that play over UDP; each tweak carries its own list); it adds one restore-point line when a suggested tweak is Moderate or riskier; it describes the app's tools only in their own exact line (so it can't say Startup apps "closes" programs); it never claims a driver is current or the latest, only where to get the newest; it never calls a setting the app offers bad; it never suggests a tweak that's already on, or one for another device than the one you ask about; it never states a number about your PC that isn't in its summary (the summary now has each monitor's refresh rate now and at most, the main one first); it says only what the app's own tools really do; and it never suggests turning off Defender or other security, unknown downloads or cheats. A tweak in an answer is a link that opens its card: nothing is ever turned on for you. "AI can be wrong: check a tweak's details before you turn it on, and keep a restore point."
• Fuller answers: the server now takes out only the wrong part of an answer (a tweak's name in a list of causes, a phrase naming one of the app's tools, a claim about the graphics driver's version, a number your PC doesn't have) instead of the whole sentence, so the causes stay. "My PC feels slow" gets an answer of its own: your PC summed up from its summary ("Your Ryzen 7 9800X3D, RTX 3060 Ti, 32 GB at 6400 MT/s and 420 Hz screen are a strong setup, so a slow PC usually comes from what's running on it rather than the hardware"), the usual causes (startup and background apps, a full drive, temperatures, Windows Update), Startup apps, Smart System Detection, the Cleaner and Game Boost, and up to 3 tweaks that fit. Input-delay answers always cover NVIDIA Reflex or AMD Anti-Lag, fullscreen, mouse polling and your main display's own refresh rate. A new question starts fresh: only a clear follow-up ("and…", "what about…", "does that…") keeps the earlier game or tweak, and a "doesn't help in" line appears only for a tweak the question names. An answer left with fewer than 2 causes is asked again once, then answered from the server's own know-how instead of an almost empty reply. "Is it safe?" about a tweak gets its risk first. The PC summary now names Combo's own Ultimate Performance plan, so it's never suggested again once it's on.
• Only the most useful tweaks: an answer suggests the Noticeable and Small tweaks that fit your question and your PC, Situational ones only when fewer than 2 of those fit, and never one that's placebo for most games unless you name it. Pause Windows Update comes up only when updates or downloads get in the way of your games, and the timer tweaks only when you ask about the timer (not for a mouse that feels delayed). The example answers on the Ask Combo AI page follow the same rules.
• Nothing is sent until you agree to a screen that shows exactly what a question carries: your question and the conversation, a short summary of this PC's hardware (shown word for word; no user or PC name, files, addresses or serial numbers) that you can switch off, the app's version, and your licence key (Plus and Premium; it holds a licence number, not your email) or, in Free, a random install ID the app made (nothing about you or your PC).
• Your own free server: the answers come from a small Cloudflare Worker you deploy on Cloudflare's free plan (server/combo-ai-worker, step by step in docs/AI-SERVER.md), using Workers AI's open Llama models (Built with Llama). It checks licence keys with the public key only, counts free questions by the random install ID and a salted hash of the IP address (never the address itself), keeps a daily pool for free questions and another for Plus and Premium so paying users are always served (an empty free pool says "Free AI questions are used up for today — upgrade for more"), keeps no logs and no questions, and can't cost money: when the free daily allowance runs out, it says "Daily AI limit reached — try again tomorrow." A paid Claude provider is built in for later and off.
• Suggested questions and example answers, "Questions left today: 2 of 3", a small "Get more questions with Premium" link in Free and Plus, friendly messages when you're offline, the server is busy or a limit is reached, and "What's sent" to see the consent screen again. Developer builds send a test token (Settings › Developer) instead of a licence key, or ask as Free without one.
• Combo's Tweaks' server is live on Cloudflare's free plan; questions go only to its address in ai.json (with a placeholder there, the app sends nothing and says Ask Combo AI isn't set up). The licence agreement (EULA.txt, section 8) and Settings › Privacy describe it; the welcome screens ask you to accept the agreement once more.

Light while you play

• Opening Combo's Tweaks no longer makes a game lag. Every start used to check all 120 tweaks: on a gaming PC that took a minute of PowerShell and WMI work on several cores (333 seconds of processor time), plus 7 seconds of start-up reads. Now starting reads only the basics (about 0.1 s), and no card is checked until its page opens. Home's "Applied by Combo's Tweaks" count comes from your backups; "Already set by Windows" is counted once every page has been opened.
• A page checks only its own cards, one at a time, at below-normal priority, so a game always gets the processor first, and not again for 3 minutes. Only the open tab's tools read anything (Debloat's app list and Autoruns, Hardware › Storage's drives, Network Priority's games). PowerShell reads run at below-normal priority too. No network activity at start: no ping, DNS test or connectivity check (as before).
• While a game runs (one that fills the screen, or a known game such as Fortnite, VALORANT or CS2, even while you've alt-tabbed out), the checks wait until it closes. A bar says so, with Check now. A change you make is still checked straight away, and Game Boost still starts with its game.
• The slow checks are fast: "Allow the computer to turn off this device" for USB hubs is one Windows query plus the device tree (0.4 s instead of 30 s), Network Discovery reads the firewall once instead of 21 times, and the start-up network snapshot comes from Windows' own tables (7 ms instead of a 1.5 s PowerShell run; nothing is sent and the network driver isn't asked). BitLocker is read only when a boot setting needs it.
• Home graph: reads only while Home is on screen and Combo's Tweaks is the window in front and not minimised. The GPU comes from NVIDIA's driver (NVML) on NVIDIA cards (0.2 ms a reading); other cards use Windows' GPU counters, read every 3 seconds.
• Clicks always land: the sidebar no longer greys out while a page is still loading, a switch no longer greys out while the cards are checked again after a change (a click on it used to open the card's details instead), and a double-click on a card no longer closes the details its first click opened.
• Performance in the log: every page's checks, every PowerShell run (time and processor time), the start-up reads, page loads, the Home graph and game pauses are Performance: lines in the log, and the debug report has a Performance section. A UI freeze: line now says how much processor time Combo's Tweaks used meanwhile and whether the whole PC was busy.

Plans: Free, Plus and Premium

• Three plans, one-time lifetime licences in AUD, GST included: Free, Plus (A$9.99) and Premium (A$19.99; a Plus owner moves to Premium for the difference, A$10.00). docs/PRICING.md lists everything each plan includes, generated from the code.
• Always free, whatever the plan and even if a licence stops working: Home, Smart System Detection, backups and restore points, Undo, Undo everything and --revert-all, every Fix, Resources, the BIOS guide, Support, Settings, the read-only tests (ping, DNS, bufferbloat, the Timer Precision Test, the MSI Mode list), the startup apps list and cleaning Windows temporary files. Free tweaks: Game Mode on, Game DVR off, visual effects for performance, transparency off, background apps off, mouse acceleration off, file extensions, widgets off, Windows tips off, ads & suggestions off, hibernation off and the Ultimate Performance plan. Quick Optimise in Free uses only these.
• Locked cards are blurred with a Plus (teal) or Premium (purple → pink) button that opens the new Upgrade screen. Clicking a locked card still opens its details: title, risk and "What can happen" are never hidden. Tools say what they need in one line (Game Boost, Network Priority, the Adapter Tuner, Timer Resolution, the FPS Limiter, Game Settings, Profiles, Uninstall, Autoruns, Network Repair, TRIM & Defragment, the full System Cleaner and the Services presets: Basic is Plus, Custom is Premium).
• Undo always works. A tweak you applied stays applied if your plan no longer includes it (its card keeps its switch, with a lock chip), until you undo it. Nothing is reverted automatically. Turning a startup app back on and ending Game Boost never need a plan either.
• Upgrade screen: a full plan comparison. At the top, Free (green), Plus (teal) and Premium (purple → pink) with their one-time price (A$0, A$9.99, A$19.99) and a button: Current plan, Get Plus or Get Premium (a Plus owner sees "Upgrade for A$10.00"), which opens Stripe's checkout in your browser: Plus and Premium at full price, or for a Plus owner the upgrade for the difference. Then a table, Features and Optimisations, with the plan names pinned at the top as you scroll: the real number of tweaks in each plan and on each page, Ask Combo AI's questions a day, support, and a ✓ or ✗ for every tool, each row with a tooltip, and a one-sentence summary per plan. It's made from the app's own plan table, so it can't promise more than the app does. Under it: the licence key box and "Results vary. No guaranteed FPS or ping gains." The user card shows your plan, and the Upgrade button is hidden once you have Premium.
• Licence keys now carry their plan. Keys made before plans existed unlock Premium, in every version. KeyGen issues Plus or Premium keys (issue --tier plus|premium), and each new key works up to the major version being sold (version 1.x for 1.0 to 1.9), so "lifetime for this major version" is enforced by the key itself; --max-major changes it. The app only ever checks keys, offline, and the private key never ships.
• The engine enforces the plan too, for the app and the command line (exit code 7: "needs Plus or Premium"), so a locked tweak can't be applied by any route. --list-tweaks and docs/TWEAKS.md show each tweak's plan.
• New licence agreement (EULA.txt), short and in plain English: Free, Plus and Premium; Plus and Premium are one-time purchases in AUD, lifetime for the major version you buy, for one person's PCs; no guaranteed FPS or ping gains; refunds as the Australian Consumer Law requires; Undo always works. Because the terms changed, the welcome screens ask you to accept it once more. The Upgrade screen and the welcome screens sum the terms up in one line, and Settings › Privacy lists every network use.
• Settings › Developer › Preview as Free / Plus / Premium (developer builds only) runs the app, and the engine, exactly as that plan would.

Polish: tabs, titles and Game Boost

• Network has five tabs: Tweaks, Network Priority, Adapter Tuner (the adapter presets, Advanced view and the other adapter cards together), Bufferbloat and Tests (the ping and DNS tests together). Network Repair moved to Backups & Fixes › Fixes. Ctrl+K still finds Ping test, DNS speed test and Network Repair.
• Card titles fit on one line at the normal window size: 42 long titles are shorter, for example Delivery Optimization off, Network throttling off, Hardware GPU scheduling on and GPU at full speed (P0). What a title left out is in its description. Win32PrioritySeparation is now Active window CPU priority (Ctrl+K still finds it by the registry name). The New label moved to the card's footer, so the title gets the whole row. Backups, profiles and Undo are unaffected.
• No cut-off text at any window size, from the smallest window to maximised: card grids only add a column when every card still has room for its title (tweak cards are at least 306 px, Game Boost's option cards 272 px, Timer Resolution's tiles 240 px), and long names wrap instead of being cut off (devices and drivers in preset cards, a download's site, the processor or graphics card above Home's graph). Device names drop Windows' (R) and (TM) marks, and a download's publisher no longer shows two full stops ("Valve Corp.."). Cards show up to three lines of description (20 px taller), and every description fits: 23 long ones have a shorter text on the card, with the full description in the tooltip and the details panel.
• Chip tooltips: every icon chip on a card says what it means in one plain line, for example "Impact: small", "Moderate risk — see details" or "Restart needed to finish". The full text is in the details panel.
• Focus ring only with the keyboard: the selected sidebar item looks the same on every page (soft fill and accent bar). The focus ring shows after Tab, the arrow keys, Space or Enter, and goes away when you click. Before, pressing Alt (Alt+Tab, a screenshot shortcut) drew it around the last item you clicked.
• Home: the usage graph starts at the left edge and fills in as readings arrive ("Collecting… 20 of 60 s"), then scrolls. Quickstart lines fit on one line.
• Upgrade is outline only (no glow), so a page has at most one filled gradient button, such as Home's Quick Optimise.
• Game Boost: the options are three small cards with an icon and a switch: Power plan, Pause notifications and Timer 0.5 ms. Each program to close is on one line, with the name from its file and what its window shows. Your choices are remembered.
• Game Boost › Start automatically (new, off by default) starts Game Boost when a chosen game opens and ends it when the game closes. The game list shows the games found on this PC, with Fortnite first, or you can choose a program. Combo's Tweaks checks every 5 seconds, only while it's open (no service). Started by a game, Game Boost never closes the game and only applies options that don't ask first; one that asks (the power plan on a laptop) waits until you start Game Boost yourself.

Premium redesign and new features

• Design system (docs/design/DESIGN-SYSTEM.md): an 8 px grid, the Poppins type scale, colour tokens with at least 4.5:1 text contrast, Lucide icons (18 px in cards, 16 px in chips), 150–200 ms motion (none in Low-end PC mode), a visible focus ring on every control and our own title bar.
• Layout: the sidebar is grouped into General (Home, Backups & Fixes, Resources, Support), Tools (Game Boost, FPS Limiter, Game Settings) and Optimisations (General, Hardware, Debloat, Network, Advanced, BIOS with a green "Guide" pill), with your profile card at the bottom. Ctrl+K opens a command palette that finds every tweak, page, tab, setting and tool. Pages have a title, a one-line subtitle and an Upgrade button (the plans and prices; hidden with Premium). Tabs have icons and a sliding underline and scroll sideways in a small window. One toolbar line holds search, Filter and Sort, with pickers on the right. Banners are slim and can be closed.
• Tweak cards: one size, three per row (two or one in a small window): a title in Title Case, a two-line description, an impact chip, up to two warning chips with tooltips, and the switch. Click a card for its details panel; cards with options have Configure. Every tweak has a plan (Free, Plus or Premium: see Plans above).
• Preset cards, two side by side under a "What is …?" card: General › Power plan (Desktop / Laptop), Hardware › GPU NVIDIA profiles (Desktop / Laptop), Hardware › Peripherals › Advanced USB (controller / keyboard & mouse), Network › Adapter Tuner (Wi-Fi / Ethernet) and Debloat › Services (Basic / Custom).
• Hardware: the GPU tab shows your card and driver version, Clean NVIDIA driver install (the DDU guide with NVIDIA's and DDU's official pages; never modified drivers) and the NVIDIA profiles. RAM adds What are EXPO and XMP? (desktops) beside rated vs actual speed. Storage has a drive picker and TRIM & Defragment with a "Last ran" chip.
• New tweaks (all off until you turn them on; each researched, with its sources and exact Undo): HDCP off (High, NVIDIA), ECC memory off (High, NVIDIA workstation cards), Optimisations for windowed games on (Windows 11), NVMe SSD power saving off, SATA link power saving off and Hard drives never spin down (plugged in), NTFS last-access updates off, Write-cache buffer flushing off (High, desktops), USB power saving off for controllers, Wi-Fi MIMO power saving off and Wi-Fi U-APSD power saving off. The keyboard & mouse USB card now finds the right devices (the old one could miss composite mice and keyboards and pick an RGB controller).
• Network Priority: the games found on this PC (Fortnite, VALORANT, Counter-Strike 2, Apex Legends, Rainbow Six Siege, Rocket League, Minecraft) with their icon and publisher, one switch each, + Add games and an honest "How it works": it only helps if your router honours DSCP, and it can't lower ping to the game server.
• Bufferbloat: what it is (with links to two online tests, opened only when you click), our A–F test now also showing download and upload speed, and where to turn on smart queue management on common routers. Combo's Tweaks doesn't throttle your upload: research showed it's unreliable on home PCs.
• Home: the greeting is the page title, the stat chips sit beside Quick Optimise, a Profiles section links to your saved profiles, the usage graph is smoother and the ping chart explains itself before the first test.
• Every page uses the new cards, buttons and notices. Backups & Restore is now Backups & Fixes, and Startup apps live in Debloat › Autoruns.
• Researched and not built, with reasons (Tweak sources › Skipped): Sleep Study off, power saving off for every device, audio kept at D0, short (8.3) names off, hard drive head parking, NVIDIA App update prompts, NVIDIA logging, VRR and power keys, an upload cap on the PC, Intel's Reduce Speed On Power Down and adapter extras.
• Engine: Network Priority can undo one game at a time (undo by target prefix), and registry keys a tweak created are removed once they're empty even when its parts are undone out of order. Two new change kinds: an entry inside a registry list value, and NVIDIA ECC.

New look on every page

• A new style everywhere: a deep navy theme with violet accents and the Poppins font, flat rounded cards with icon chips, coloured pill buttons and a matching light theme. Only the look changed: every feature, check, confirmation and Undo works as before.
• Home: "Welcome back" with your Windows first name, Quick Optimise as the main button (still previewed first), cards for backups, help and the welcome tour, a live graph you switch between CPU, GPU and RAM, Quickstart steps that say what each does, and What's new as three cards. The four "How to use" steps are now in the welcome tour.
• Sidebar: grouped into General, Tools and Optimisations, with the search box at the top and your profile at the bottom. Only the page you're on is highlighted; hovering no longer looks like a second selection.
• Fixed: live use stuck on "CPU 0 %" and "GPU –". The first reading now measures over a moment, the graph starts as soon as the app opens, and a failed reading no longer stops it.
• Toasts are dark cards. The window is a solid colour on Windows 10 and 11 (no see-through effect), so Low-end PC mode now only slows animations.
• Advanced › Timer Resolution, new layout: the current, max and min resolution live at the top (every 2 seconds); Measure sleep times Sleep(1) with each preset and fills in a row per value (Sleep and Delta), marking the steadiest one green; Set timer resolution has the presets as option buttons with Recommended on the winner (0.507 ms before a test), and Apply/Release. On Windows 11 its two boxes turn on Global timer resolution requests and the tray copy through the usual preview and backup. Lowest input delay mode and the Timer Precision Test are below. The 1.0 ms hold option is gone.
• Debloat › Services: two presets side by side, Basic and Custom, each showing whether it's on, how much keeps working and how much background work is left. Custom lists Basic's services plus Wallet Service, Windows Insider Service, Program Compatibility Assistant Service and Phone Service (all optional, unticked), each with what stops working and our advice. Switching puts every service back first; Undo restores each exact start type. Still never Windows Update, Windows Security, networking, the Store, Bluetooth, Xbox or audio.
• Program icons: Apps, Uninstall, Autoruns, Startup apps, Game Boost and the FPS Limiter's game picker show each program's own icon (from Windows; none are bundled), with a plain placeholder when there's none. Every tweak card now has its own icon.
• Polish: our own tick boxes, option buttons and switches everywhere (no more half-drawn ticks), the switch knob slides, tables have one row style with hover, lists show a soft placeholder while loading, pages fade in, cards lift slightly on hover, and every tool card has the same header. Checked at 100 % and 150 % display scale and at the smallest window size.
• Fixed: a tweak card's status ("Not applied", "Partially applied") was cut off next to a long impact label; the impact now sits on the Details line. A tweak checklist's switch applied its optional, unticked lines too. "Export debug logs" showed a stray letter instead of its icon.

Debloat page (the Cleaner, renamed)

• Debloat has four tabs. System Cleaner is the cleaner you know (scan first, nothing personal).
• Services: a Basic preset (Downloaded Maps Manager → Manual, Retail Demo and Geolocation (desktops) → Disabled) and a Custom pick that can also switch off the sensor services (desktops), Sync Host and a few more optional services. Only each service's start type changes, and Undo puts back exactly what was there. Windows Update, Windows Security, networking, the Store, Bluetooth, Xbox and audio keep working.
• Uninstall: Windows apps you can remove for your account only (News, Weather, Solitaire, Clipchamp, To Do, Copilot and others; Phone Link, Outlook and similar as optional; Calculator, Photos and other tools marked "keep recommended"). Each removed app gets a Reinstall from Microsoft Store button. The Store, App Installer, Windows Security, Edge, Xbox and gaming parts, codecs and other parts of Windows are never listed.
• Autoruns: everything that starts with Windows: Run keys and Startup folders (with Task Manager's switch, undone by Undo everything), plus scheduled tasks and services from other companies, each with its command, publisher and our suggestion (Keep, Your choice, Safe to turn off, Check first) and a warning where turning it off may break something.

Network tweaks and BIOS guide entries

• Network › Tweaks (4 new cards, none lowers your ping, and each says what it does instead): Receive Side Scaling on (only changes anything if something turned it off); Limit Windows' background downloads to 25, 50 or 75 % of your connection (Windows' automatic update downloads only; Steam and your own downloads aren't limited; Pro and higher); Ignore ICMP redirects (Microsoft's security baseline); Network discovery off (Moderate: hides the PC on your home network like Control Panel does, by turning off only the Network Discovery firewall rules for Private networks; Undo turns exactly those back on).
• BIOS guide: nine researched entries with where to find them on ASUS, MSI, Gigabyte and ASRock boards: CPPC and Preferred Cores (check it's on), C-states (keep Auto), PCIe ASPM (keep Auto), integrated graphics (optional, desktops only), ErP and wake events, USB4 lane sharing, ACP gating (leave Auto), hibernation (a Windows setting, not a BIOS one) and Precision Boost Overdrive (notes only: AMD says it voids the warranty). AMD and Intel PCs see their own names; laptops are told what to leave alone.
• Researched and not built, with reasons: TCP auto-tuning restricted/disabled, IPv6 transition technologies off, offloads off, packet coalescing off, temporary IPv6 addresses off, weak host and neighbour cache size.
• Engine: two new change types, Receive Side Scaling and firewall rule on/off; a firewall rule change may only turn a Network Discovery rule off, so the firewall can never be opened.

Hardware page: researched GPU, storage and USB tweaks

• Hardware › GPU (NVIDIA cards only; nothing is on until you turn it on):
  • NVIDIA profile preset (High risk): Desktop sets Low latency mode On, Power management Prefer maximum performance and an unlimited shader cache; Laptop sets only Low latency mode (the Desktop preset is refused on laptops). Before the first change, a copy of all your NVIDIA profiles is saved to the backups folder; Undo puts back each setting exactly, including values you had set yourself.
  • Keep the graphics card at full speed (P0) (High risk, desktops only): written only to the settings key Windows names for your card, with the Safe Mode recovery steps on the card and a restart.
  • NVIDIA HD Audio off (Moderate): turns off the HDMI/DisplayPort sound device like Device Manager does; Undo turns it back on.
  • NVIDIA crash reports off: turns off NVIDIA's crash-report tasks, only the ones on your PC. Driver and app updates are never touched.
  • "Driver changed — re-apply?": after a graphics driver install removes a GPU tweak's setting, Hardware › GPU and Advanced › MSI Mode say so, name the new driver, and offer Re-apply (fresh backups, on the key the new driver uses), Undo them or Not now.
  • The DDU guide now covers the BitLocker recovery key, a restore point first, DDU's "Prevent downloads of drivers from Windows Update" option (and how to turn driver downloads back on) and re-applying GPU tweaks afterwards. GPU tab tips explain when a clean install is worth it and why AMD and Intel cards get no driver tweaks.
• Hardware › Storage: Drive power saving off (plugged in): NVMe latency tolerances, SATA link power management and hard disk sleep, plugged-in values only. Optimise drives: pick a drive and run Windows' own optimiser (TRIM for SSDs, defragmenting for hard drives) with "Last optimised" from Windows and from Combo's Tweaks; cancel stops it safely.
• Hardware › Peripherals: USB 3 link power saving off (plugged in) for USB 3 devices that drop out.
• Researched and not built, with the reasons in docs/TWEAK-SOURCES.md: NVIDIA App update prompts, NVIDIA telemetry registry values, driver logging, HDCP off, DMA remapping off, per-CPU DPC, display power saving, GPU ASPM keys, clock/power gating keys, contiguous memory, Direct Flip keys, the PCI latency timer, UVM off, AMD/Intel driver tweaks, NVMe/Storport registry power values, NVMe idle timeout 0, mouse/keyboard queue size and per-device USB power values.
• Engine: a new change type turns a device off or on exactly (Device Manager's Disable/Enable), with a golden backup file; NVIDIA profile changes record where the copy of all profiles was saved.

General page: researched tweaks (Core, Power, Privacy, Quality of life, Apps, Power plan)

• General › Core (15 new cards, all off until you turn them on): startup delay for apps off; thumbnail cache auto-clean off; close apps that block shutdown; web results in Windows Search off (the new Settings switches on Windows 11 with the September 2026 update, the policy on older Windows); Paint AI features off; Edge startup boost and background running off (Edge stays installed); printing services off; reserved storage off; search indexing off; Bluetooth services off (only offered when no Bluetooth device is paired); Copilot off (Windows 10 and Windows 11 22H2/23H2); Xbox services off (only offered when the Xbox app and Game Pass aren't installed; controllers keep working); automatic driver updates off; Storage Sense off; and Pause Windows Update for 1 to 5 weeks, Windows' own pause, never longer, with the resume date on the card.
• Transparency, visual effects, background apps and Recall/Click to Do moved to General › Core.
• General › Privacy (9 new cards): ads and suggestions off (Start, Settings, lock screen, File Explorer, welcome pages); advertising data (tailored experiences) off; advertising ID off; diagnostic data to required only; feedback prompts off; error reporting off; activity history off; Remote Assistance off; Connected User Experiences and Telemetry off (not on work or school PCs; warns that Xbox achievements may stop unlocking).
• General › Quality of life (12 new cards): show file extensions; show hidden files; File Explorer opens to This PC; classic right-click menu (Windows 11); always show all tray icons (Windows 10); Control Panel on the desktop; widgets off; Windows tips off; suggested app installs off; no automatic device-maker app downloads; full-quality wallpaper; and Combo's Tweaks wallpaper: four wallpapers made for Combo's Tweaks (Nebula, Neon grid, Ember, Tide) with a preview on the card, and Undo puts your own picture back.
• General › Apps: a panel lists which of ten apps are installed (Adobe Creative Cloud, Brave, Discord, Firefox, Chrome, Edge, OBS Studio, Spotify, Steam, Streamlabs), says what can be done for each, and has their "starts with Windows" switches (Task Manager's switch, so it survives app updates). Browser cards, shown only when the browser is installed: Chrome background and usage reports off; Edge required diagnostic data only; Brave background and data collection off; Firefox telemetry off. Updaters are never touched.
• General › Power plan: Combo's Desktop plan and Combo's Laptop plan, both made from Balanced (so they work on Modern Standby laptops), with your sleep and battery settings copied in, simple 1–5 ratings, and a "Your power plan" panel showing the active plan and processor. Undo makes your previous plan active and deletes ours. Only one power plan (including Ultimate Performance) can be on at a time.
• General › Power (7 new cards): hibernation off; hybrid sleep off; never sleep when plugged in; sleep off completely (desktops); energy estimation off (desktops); USB hub power saving off (desktops); audio power saving off (stops the start of sounds being cut off; laptops keep their battery setting).
• Researched and not built, with the reasons in docs/TWEAK-SOURCES.md: serial port services, VPN services, hung-app timeout, shorter shutdown wait, Copilot on Windows 11 24H2+, Sleep Study, power telemetry, USB Audio 2.0 idle power-down, the Help Experience Program, a separate content-delivery card, Application Telemetry/Inventory policies, Task Manager history, telemetry trace sessions, WMI logging, a classic Alt+F4 dialog, taskbar Chat, solid taskbar, Suggested actions and deleting the default power plans.
• Engine: a tweak can now say live why it isn't offered on this PC (for example "Bluetooth devices are paired"), and cards can show a note (when paused updates resume). The one Windows Update policy a tweak may set is "leave drivers out"; the "pause forever" value stays forbidden.

Researched tweaks, Home and Smart System Detection

• Home page: a welcome header; Backups (how many backups you have, and Create backup for a Windows restore point); Need help? (email support, the welcome tour); How to use in four steps; a live graph of CPU, graphics and memory use for the last 60 seconds (it only runs while Home is on screen); a Quickstart checklist that ticks itself (backup, turn on a tweak, clean files, remove apps you don't use, optimise an app, run Smart System Detection); and What's new from this changelog.
• Smart System Detection (profile menu): checks Windows, your account, processor, graphics card and driver age, memory speed against its rated speed, drives, monitor refresh rate, network, power plan, Game Mode, GPU scheduling, VBS and MSI mode. Each line says Good, Info, Tip or Warning, with a link to the tweak or guide that helps. It only reads: nothing changes until you turn a tweak on yourself. Shows the last scan time and has Rescan.
• Every card now says how well its claim is backed: Documented (Microsoft or the hardware maker documents it), Community (a community finding we checked) or Unverified gain (the setting is real, the benefit isn't proven). The card's details list the sources, and docs/TWEAK-SOURCES.md has every tweak with its exact change, Windows' default, how Undo restores it and the sources.
• Settings: Start with Windows (off by default; starts Combo's Tweaks in the tray at sign-in without admin rights, through the engine so it undoes exactly), View logs, Export debug logs (one text file with user names, user folders, account IDs and network addresses removed), Report a bug, Language (English for now), Low-end PC mode (plain window background and fewer animations) and your administrator status. A profile menu at the bottom left opens Settings, Smart System Detection and Support.
• Win32PrioritySeparation moved to General › Core and now has a value picker: Windows' default (2), 0x26, 0x28, 0x24 or 0x18, or your own value (0–63, decimal or hex), each explained in plain words.
• Engine: new change types for hibernation and reserved storage, each restored exactly; service start values may only be changed for listed services, and only to Manual or Disabled.

Tweaks and pages

• FPS, Input Delay, Network & Ping and Internet pages with honest impact ratings, risk levels and "What it changes" details.
• Quick Optimise and three built-in profiles (Balanced, Laptop Safe, Competitive (Desktop)), always with a full preview.
• Your own profiles: save the tweaks you have on now (including your DNS choice), apply them later, or from the command line with --apply custom:<name>.
• DNS provider picker with a DNS speed test, and a ping test with "Before" and "After" comparison.
• Game Settings for Fortnite (frame rate limit, window mode, view distance, quality, V-Sync, Performance mode) with "Restore original".
• Startup apps: one switch per program, like Task Manager. Nothing is uninstalled.
• Cleaner: temporary files, shader caches, Windows Update download cache and the Recycle Bin.
• Network Repair (flush DNS, renew the address, check the connection) with an optional Winsock reset.
• FPS Limiter page: your monitors with their exact refresh rates; G-SYNC/FreeSync safe cap (refresh − 3 %), match refresh, custom or unlimited.
  • NVIDIA: Max Frame Rate set through NVIDIA's own driver settings API (NVAPI DRS), globally or for one game, with the old value backed up and an exact Restore. Manual steps when the driver API isn't available.
  • Game files: Fortnite's FrameRateLimit (any cap from 20 to 1000) and CS2's fps_max in autoexec.cfg, each with a preview and its own Restore. Both are refused while the game is running.
  • Steps instead of edits: AMD, Intel and Apex Legends get step-by-step instructions. Apex's settings files have no frame-cap setting, so nothing is faked.
  • "Why is my FPS stuck at X?" lists every active cap.
• Lowest input delay mode (Advanced › Timer Resolution, Windows 11): one button and one confirmation. It tests 0.500, 0.504, 0.507 and 0.510 ms with Sleep(1), shows the results table and holds the value with the lowest delay + jitter; turns on Global timer resolution requests (restart needed); and, if you tick it, starts Combo's Tweaks minimised to the tray at sign-in (one per-user startup entry, no admin rights, no service, scheduled task or driver) to keep the timer held. Turn it all off undoes every part. Nothing is downloaded or bundled. Gains are small (often under 1 ms) and vary by game; Reflex On + Boost matters more.
• Advanced › Timer Resolution: the read-only Timer Precision Test (500 × Sleep(1), before/after chart), "Hold timer resolution while Combo's Tweaks is open" (Off / 1.0 / 0.5 ms, never saved, released on close), and "Global timer resolution requests" (Windows 11 only, Moderate, restart needed).

New look: card grid, tabs and the Extreme risk level

• New pages: General (Core, Privacy, Quality of life, Apps, Power plan), Hardware (GPU, CPU, RAM, Peripherals, Storage), Advanced (MSI Mode, Timer Resolution) and Network (Tweaks, Adapter, Ping test, DNS speed test, Repair). They replace the FPS, Input Delay, Network & Ping and Internet pages; every tweak kept its ID, backups and undo.
• Card grid: up to three cards per row (two or one in a narrow window). Each card shows an icon, the name, a two-line description, the risk badge, warning chips, a 1–3 bar impact meter, its status and the switch bottom-right. Click a card (or "Details") to open what it changes, why, side effects and how to undo.
• Search, filters and sort on every tweak page: search looks across all tabs of the page; filter by risk, impact, applied or not, needs reboot and new; sort by name, impact, risk or newest.
• "What can happen": every tweak lists 1–4 plain-English consequences on its card and in every confirmation.
• Warning chips: Anti-cheat warning, Security warning, Needs reboot, Redo after driver update, Laptop: battery drain, and a New badge.
• Extreme risk level (purple on black): hidden until Settings › Show extreme tweaks is turned on after a warning (at least 3 seconds and a tick). Each Extreme tweak then needs I UNDERSTAND typed in its confirmation, always makes a restore point first, is never in a profile or Quick Optimise, and can't be applied from the command line. Undo always works, even after hiding them again.
• New General tweaks (New badge; never in a profile or Quick Optimise; each with exact undo): All notifications off, Window animations off (the "Do not allow window animations" policy), Early and experimental features off, First sign-in animation off, Customer Experience Improvement Program off, Recall and Click to Do off (Windows 11), Inking & typing personalisation off, Online speech recognition off, and Data-collection scheduled tasks off (Moderate): a checklist of 10 Windows tasks (compatibility, CEIP, disk-check reports, feedback, error-report queue, offline maps). Untick any you want to keep; tasks that aren't on your Windows version are skipped; only the ticked tasks are disabled and undo enables exactly those that were enabled.
• Advanced › MSI Mode (read-only for now): your graphics, audio, network, NVMe, SATA and USB controllers with their MSI setting (On, Off or driver default) and interrupt priority, read in the background when the page opens. Nothing is changed.
• Timer presets on Advanced › Timer Resolution: hold 0.500, 0.501, 0.503, 0.504, 0.506 or 0.507 ms while Combo's Tweaks is open. Find recommended tests the presets with Sleep(1) (about 2 seconds, nothing on the PC changes) and marks the best one "(recommended)"; Lowest input delay mode's test marks it too.
• Backups & Restore › Backups: Windows restore points and Combo's Tweaks backup files in one list (name, date, type badge Windows / Combo's Tweaks / Automatic), with search. Create restore point makes a named Windows restore point. Restore asks first: a Windows restore point restarts the PC and lets Windows go back to it; a Combo's Tweaks backup file undoes exactly the changes recorded in it (with the full list shown first). Delete selected asks first and never deletes a backup file that still holds changes you can undo.
• Resources page:
  • Shortcuts open Windows' own tools (System Configuration, Control Panel, Device Manager, System Properties, Task Manager, Disk Management, Services, Event Viewer, Windows Update, Sound, Display, Power Options, Network Connections). Only these fixed commands can be started.
  • Downloads: Steam and the Epic Games Launcher download from the maker's own servers over HTTPS only (every redirect must stay on their domain), and the file is kept only if Windows trusts its digital signature and it is signed by Valve Corp. / Epic Games Inc. Otherwise it is deleted and the official page opens. It is saved to your Downloads folder and never started for you: Open folder and Run installer are buttons you press. The other tools (graphics drivers, DDU, CRU, MSI Afterburner, Ryzen Master, HWiNFO, CapFrameX, CPU-Z, GPU-Z, CrystalDiskInfo, OCCT, 7-Zip) have no fixed official download link, so their button opens the maker's official page; each card shows the source domain.
  • Guides: EXPO/XMP, Resizable BAR, monitor refresh rate, NVIDIA Control Panel basics, and a clean driver install with DDU.
• Cleaner upgrade: a compact checklist with the size of each item after Scan sizes, Select all, Last ran (remembered) and Start cleaning. New items: browser caches (Chrome, Edge, Firefox; history, passwords, cookies and sign-ins are never touched), crash dumps and error reports, Delivery Optimization cache, graphics driver installer leftovers (C:\NVIDIA, C:\AMD), thumbnail cache, Steam and Epic launcher caches and logs (never games or saves) and Prefetch (Moderate: apps and games open slower for the first few launches, no FPS gain). The same safety rules apply to every item: nothing changed in the last 24 hours, nothing in use, no links followed, protected folders refused. Browser history isn't offered: browsers keep it open, so use their own "Clear browsing data".
• Network page, new tabs:
  • Network Priority (Moderate, restart): a Windows QoS policy that marks one game's traffic (by its program name, e.g. cs2.exe) as high priority, through the engine with exact undo (Remove all). Honest note: it only helps on this PC; routers and providers usually ignore the marks, so it won't lower your ping to the server.
  • Adapter Tuner (Moderate): Receive Side Scaling, receive/transmit buffers and flow control of your active adapter, with what we recommend (only values the driver lists). Applying restarts the adapter (the engine asks first) and Undo puts every value back.
  • Bufferbloat test: pings 1.1.1.1 with nothing running, then while downloading and while uploading to Cloudflare's public speed test (shown on the card; nothing is sent until you press Start), and grades the extra delay A–F with a router tip (SQM / cake / fq_codel).
• Hardware tabs: "Your hardware" on GPU, CPU, RAM and Storage (read-only, nothing is changed): graphics card and driver (with NVIDIA's own version number), monitor refresh rate, HAGS state, processor, base clock and motherboard, memory sticks with speed now vs rated speed (also read from the part number), drives with free space and TRIM. Honest tips, each with a step-by-step guide where one helps: memory below its rated speed → turn on EXPO/XMP in the BIOS (laptops: usually can't be changed), one stick → dual channel, 60 Hz monitor, nearly full system drive, Windows on a hard disk, 3D V-Cache processors keep the Balanced plan.
• BIOS guide page: your motherboard, BIOS version and date, UEFI or legacy start-up and Secure Boot; what to change (memory profile EXPO/XMP, Resizable BAR), what to keep on (Secure Boot and TPM) and what to leave alone (voltages, manual overclocks), with where each one is on ASUS, MSI, Gigabyte, ASRock, Dell, HP and Lenovo BIOS screens. An old BIOS gets a careful update tip. Restart to BIOS (UEFI PCs) asks first and warns about BitLocker. Combo's Tweaks never writes BIOS settings.
• Game Boost page: before you play, tick programs to close and/or the Ultimate Performance plan, Pause notifications and a 0.5 ms timer hold, then Start Game Boost. Programs are asked to close like clicking their X (never forced); the power plan and notifications go through the engine with a backup; options that are already on are left alone. End Game Boost puts back exactly what it changed and can reopen the closed programs. Windows' own programs and anti-cheat are never listed. Nothing is ticked by default, and it's remembered if the app closes.
• Backups & Restore › Fixes (first batch of six): Audio & microphone, Bluetooth, Fax & printing, Low internet speed (undoes Combo's Tweaks' own network tweaks and sets TCP auto-tuning back to normal), Restore Auto Game Mode, and Reset DNS to automatic (undoes our DNS choice first; refused on a fixed IP address). Each shows what it changes before you press Fix, asks through the engine, saves the old values, and Undo fix puts them back. Service start types stay forbidden for everything else: the only exception is putting eight named audio, Bluetooth and printing services back to their exact Windows default.
• Advanced › Devices tab removed (it was empty).
• "Extreme tweaks — read first" replaces "Why we don't do this" on the timer section, and is shown in Settings and on Advanced › Security.

Responsiveness

• The window no longer freezes while Combo's Tweaks works: checking every tweak (including the PowerShell reads of network adapters and devices), planning, applying and undoing (including creating a restore point), the NVIDIA driver, Steam and game files, startup apps, backups, BitLocker and the network tests all run in the background, with "Loading…" states and time limits for reads.
• Apply, Undo and every other change can't be started twice: the progress overlay is up from the click.
• The FPS Limiter reads the NVIDIA driver once per page visit (and when you pick another program), not on every key press.
• A freeze watchdog writes UI freeze: lines to the log (what was running and the window's call stack) when the window doesn't respond for 2 seconds. It can no longer close the app if background work ends at the moment it writes.
• Faster start and previews, far less memory: the check that every change stays within what its tweak declares used a slow kind of pattern matching (about 0.7 seconds and half a gigabyte of memory at start, and more on every preview and apply). It now takes a few milliseconds.
• Unexpected errors show an error message instead of closing the window; start-up problems show a message instead of spinning forever.
• Combo's Tweaks now asks for administrator rights itself when it starts (the same UAC prompt as before). This lets the tray copy of Lowest input delay mode start at sign-in without admin rights.

Safety

• Every change is backed up before it's written; Backups & Restore can undo one change or everything, also in Safe Mode and from the command line (--revert-all).
• A restore point is created before the first change of each session (the app asks if Windows can't make one).
• An interrupted change (power cut, crash) is found at the next start and can be undone.
• High-risk changes wait while Windows is finishing an update (restart pending or an installer running); other changes show a note, and undo never waits.
• After a boot-setting change, "Restart now" offers to pause BitLocker for exactly that one restart, and the banner offers "Resume BitLocker now" until Windows restarts.
• The backups folder is checked for safe permissions and replaced if anyone else could change it.
• Game settings files are never written through a link (symbolic link or junction), and the engine permanently refuses the HPET/useplatformtick/tscsyncpolicy boot settings.
• When undo can't run (for example a game is open), the message says why ("CS2 is running. Close it, then try again.").

Command line

• --scan, --dry-run, --apply, --revert-all, --report, --list-tweaks, --list-profiles and --export-diagnostics, with documented exit codes.
• --suspend-bitlocker / --no-suspend-bitlocker for boot-setting tweaks when BitLocker is on.
• --fps-cap <20-1000|unlimited> [--game <exe>] (NVIDIA Max Frame Rate) and the read-only --timer-test [--samples N].

Not in this build

• GPU MSI mode (High risk, Advanced › MSI Mode) now ships: the per-device MSI switch, for the graphics card only. One red confirmation, restore point first, backup + exact undo, and the Safe Mode steps in its text in case Windows won't start. The other two High-risk tweaks (VBS / Memory Integrity, dynamic tick) stay held back until they pass the Safe Mode checks in a virtual machine.
• Payments and code signing are paused until selling starts.
