![PC Tweaker 1.20.0 Change history showing synthetic before-and-after registry values and recorded changes; Pro-view browser demo with visible sample-data disclosure]()
This example shows the history interface, not evidence of a real system change. Restore controls apply to supported settings; cleanup and repair have separate recovery limits.
Start with one task: review a setting, read its trade-offs, apply it if appropriate, and use its restore control when supported. Free includes core tools without an account. See what changes on your system before tuning.

Safe download via Winget
Download an installer from an official channel above, or use Windows Package Manager:
winget install --id AurelioAvila.PCTweaker --exact
To check for a package update:
winget upgrade --id AurelioAvila.PCTweaker --exact
Package catalogs can lag behind a release. Check the release version before installing. Windows 10/11 x64 is the current binary target; individual features depend on the Windows build, edition, drivers and available hardware. App compatibility does not extend Microsoft's support lifecycle for your operating system.
| Application | Use it for | Official page |
|---|
| PC Tweaker | Review Windows settings, collect DPC/ISR diagnostics and inspect supported process-placement controls. | PC Tweaker |
| PC Tweaker Uninstaller | Review an uninstall command and removal risk, then inspect leftovers and the removal receipt. | Uninstaller |
| Tweaky Driver | Review a driver package and its source before deciding whether to install it. | Tweaky Driver |
These are separate applications with their own licences. PC Tweaker Lifetime includes 12 months of Uninstaller Pro from the first Uninstaller sign-in with the same account; other offers and renewals are described on each product’s page.
Diagnose before changing a setting
- DPC/ISR latency on Windows 11: capture the failing workload, investigate driver attribution and compare one change at a time.
- Ryzen X3D core parking and steering: distinguish the power-plan policy from process CPU sets, and verify the reset path.
- AMD X3D and Intel Hybrid Game Sessions: check supported topology, background-process exclusions and automatic restoration before comparing frame times.
- Windows privacy and rollback: inspect the exact registry values, record absence as well as data, and restore supported changes.
- Windows processes and services: what each common process or service does, how to check its file and signature on your own PC, and which ones to leave alone, with Microsoft sources.
- Windows tweaks explained: every control in the app, with the exact value it sets, the manual steps and how to undo it.
Closing and reopening PC Tweaker
Closing the window keeps PC Tweaker running in the Windows notification area. Click its icon to reopen it, or right-click and choose Exit PC Tweaker to quit. To make closing the window quit instead, clear Keep running in the background in the icon's menu. Windows may place the icon in its hidden-icons panel.
What's new in 1.20
-
An Audio section. See every sound device in use with its real format, effects, spatial sound and Equalizer APO status, with findings that explain what is wrong: a Bluetooth headset stuck in call mode, a muted or very quiet microphone, Equalizer APO installed but not active.
-
Fixes for common sound problems. "Don't lower my game during calls" stops Windows lowering every other sound by 80% while a call app uses the microphone, and "Fix Bluetooth volume control" helps when Bluetooth volume does not respond or jumps. Pro keeps HDMI audio, the sound chip or USB audio from switching off after silence, and restarts an audio device in one click. Every change can be restored with one click.
-
Check for crackles. A 10-second driver latency trace against Microsoft's limits (100 µs per DPC, 25 µs per interrupt), grouped by area. It asks for administrator approval and changes nothing.
-
Clear Free and Pro boundaries. The catalog has 84 controls: 48 Free and 36 Pro. Registry discovery is free; registry cleanup is Pro and saves a .reg backup. See Free and Pro for plans and what changes on your system for recovery limits.
See the 1.20.0 release notes for the full update.
What's new in 1.19
- Scan 2.0, with the findings in view. Review 19 checks across performance, junk files, startup, privacy, registry, memory, hardware and latency. Choose individual supported fixes after inspecting the results.
- A read-only hardware audit. Inspect RAM speed, PCIe link and Resizable BAR findings when Windows exposes the information, with guidance on what to check next. Firmware settings remain under your control.
- Proof of change for supported actions. Compare before-and-after measurements and save the result as a PNG. The comparison can report no measurable difference; a configuration score is not an FPS benchmark.
See the 1.19.0 release notes for the full update. The official browser-demo previews above use synthetic data; native results depend on your PC.
What's new in 1.18
- Every value before it is written. Each control has a "What this changes, exactly" panel with the value as it is now and as it will be set. If an application fails partway, the values already written are restored at once.
- Windows AI controls. The catalog has 84 controls, 48 Free and 36 Pro, including Click to Do, the Windows AI Fabric service and the AI features in Microsoft Edge, Paint and Notepad.
- A measured Before & After. PC Health runs each timed test at least 7 times and reports a difference only when the two series are clearly apart.
- Change history by session. Registry values before and after each change, with undo for one change, a whole session or everything still in effect, plus filters and export.
- Re-apply after Windows updates. A check at sign-in lists only the tweaks a cumulative update put back, one checkbox each. Nothing is re-applied on its own.
- 1.18.2. Pro keeps working when the PC's clock runs behind, account errors appear in the app's language, and the account menu shows the plan each product has.
- 1.18.3. Change your password and email from the account menu, account emails in the app's language, and nothing undone under a running game when Pro ends.
- 1.18.4. Updates are checked on dl.pctweaker.app as well as GitHub, and the change preview reads correctly when a control sets a single value.
- 1.18.5. Clarifies startup, menu, hover, background-app, update-sharing and window-display controls in all six languages. Settings and restoration behavior are unchanged.
- 1.18.6. Administrator changes to scheduled tasks with spaces in their path work, the Game Sessions list survives an interrupted save, and the administrator helper loads Windows libraries from System32 only.
- 1.18.7. Time limits on every Windows tool and on the administrator helper, power plan restores that survive a deleted plan, a polite Explorer restart, and changes that follow the signed-in user when another administrator approves UAC.
- 1.18.8. The notification-area menu and the first-close notice follow the language chosen in the app.
- 1.18.29. Plans & pricing now opens straight on the plans, with a slim offer bar and clearer prices. A new Support entry sits in the sidebar. Manage your subscription from the account menu: see your plan, price, renewal date and card, cancel at the end of the paid period (with an optional reason) or resume it. Subscribers now see their own plan and price. Interface polish: text you do not need to copy no longer gets selected, better contrast on buttons, cleaner focus rings and several small layout fixes.
- 1.18.28. Routine maintenance update.
- 1.18.27. New Copy diagnosis button on the scan screen, for support requests. Your account menu now lists the PCs signed in with your account. When the service asks you to slow down, the message says how long to wait.
- 1.18.26. Routine maintenance update.
- 1.18.25. Routine maintenance update.
- 1.18.24. Routine maintenance update.
- 1.18.23. Every language has been reviewed end to end: clearer, more accurate wording in Italian, French, Spanish, German and Portuguese (Portugal), and PC Health now explains each part of your score in your language.
- 1.18.22. Settings that are already in place on your PC now show an "Already set" label, even when Windows or another tool changed them, and a scan no longer suggests them.
- 1.18.21. Routine maintenance update.
- 1.18.20. Routine maintenance update.
- 1.18.19. Routine maintenance update.
- 1.18.18. Routine maintenance update.
- 1.18.17. Restore points recorded honestly: a point Windows reused is shown as reused, never as a new one, and admin tweaks request one when the app already runs as administrator.
- 1.18.16. Maintenance and security hardening.
- 1.18.15. Routine maintenance update.
- 1.18.14. Routine maintenance update.
- 1.18.13. The 3-day free trial in the title bar on every screen, with the days left while it runs, and on the scan's Pro recommendations; the whole menu fits short windows in every language.
- 1.18.12. The 3-day free trial is easy to find on Plans & pricing, lower plans read "Included in your plan", and a copied licence file no longer unlocks Pro on another PC.
- 1.18.11. Routine maintenance; the version Invite a friend will need.
- 1.18.10. Routine maintenance; gets the app ready for Invite a friend, coming soon.
- 1.18.9. Routine maintenance; the account menu names each plan Free, Pro or Lifetime, and text fields show a single focus ring.

What you can do
| Area | Controls and tools |
|---|
| Gaming | Game Sessions with optional core steering, supported gaming settings, hardware scheduling options, X3D placement controls and a before/after network check |
| Performance | Power configuration, startup controls and foreground scheduling settings |
| Hardware | Available sensor readings, a DPC/ISR latency trace that names the responsible driver, supported thermal profiles and driver updates through Windows Update |
| Debloat | Optional Windows apps removed for the current account only, verified by publisher, with removal history and reinstall links |
| Privacy | Supported Windows advertising, tracking and diagnostic settings; optional password breach lookup |
| Maintenance | Integrity checks, guided repair, storage analysis and cleanup with operation-specific recovery limits |
| Interface | File extensions, taskbar options, appearance and supported Windows preferences |
Read the effect and trade-offs before applying a setting. A disabled tweak is not evidence of a fault, and a higher configuration score is not a measured performance gain.
Ready-to-use profiles
Gaming, Study and Work are included in Free. Open Profiles, review or customize the selection, then apply the pending tweaks with one click. Each template explains its tradeoffs; optional settings start unchecked. Profiles add the selected settings without undoing other tweaks. Restore individual changes from their category. Results depend on your hardware and workload; no FPS gain is promised.
Native power controls
The catalog contains 84 controls: 48 Free and 36 Pro. The five power-policy controls change only mains-power policy in the selected Windows plan. They record the original plan and value before writing, verify the result, and leave battery policy unchanged.
| Control | Access | Purpose and limits |
|---|
| CPU energy-performance preference | Free | Favors performance on systems with autonomous CPPC support; power use and heat can increase. |
| USB selective-suspend diagnosis | Free | Investigates wake or disconnect problems. Windows recommends leaving selective suspend enabled normally; restore after testing. |
| PCIe link power management | Pro | Disables ASPM for troubleshooting devices affected by link transitions; idle power use can increase. |
| Short-thread scheduling preference | Pro | Prefers performant cores on CPUs with multiple efficiency classes; does not impose fixed affinity. |
| Long-thread scheduling preference | Pro | Prefers performant cores for longer work on compatible hybrid CPUs; other cores remain available. |
These controls use Windows power APIs. Unsupported hybrid settings are refused before a system write. No FPS, DPC-latency or micro-stutter improvement is claimed without a workload-specific measurement.
Restoration writes the previous effective AC value back to the original plan. If that value was inherited, it becomes an explicit plan value after restoration; later changes to Windows defaults will not automatically replace it. PC Tweaker does not change protected registry permissions or reset unrelated plan settings to remove that override.
What changes on your system
PC Tweaker can change registry values, power settings, services, startup entries and selected network settings. Other tools interact with files, Windows repair utilities, drivers or supported hardware controls. Administrator access is requested for operations that require it.
| Operation | Recovery scope |
|---|
| Supported setting tweaks | Previous values are stored for individual restore and Restore All. Check each operation's result. |
| Cleanup sent to the Recycle Bin | Recoverable while the files remain in the bin. This does not free their occupied space until emptied. |
| Third-party cache cleanup | Deletes selected caches permanently. Applications may need to rebuild them; shader rebuilding can cause temporary stutter. |
| Selective cookie cleanup | Copies the database before changing it; restore follows the cleaner's instructions. |
| DISM/SFC, driver updates and hardware controls | Separate recovery procedures and limits; these are not covered by a universal registry rollback guarantee. |
Restore All is not a Windows system image or a recovery guarantee. Keep normal backups for data you cannot replace. Settings that reduce security, including disabling Memory Integrity/VBS, have material trade-offs; inspect the disclosure before considering them.
There is no universal FPS, micro-stutter or DPC-latency improvement. Results depend on the workload and starting configuration. A settings count or health score is not a benchmark.
The following compact benchmark register distinguishes measured results from missing evidence:
| Test | Metric | Verified comparative result |
|---|
| Repeatable game replay | Mean FPS, 1% low, p99 frame time, stutter-event count | Not yet established by a reproducible result package linked here |
| CPU benchmark | Repeated single- and multi-thread scores | Not established |
| DirectX graphics benchmark | Graphics score, frame-time distribution | Not established |
| Driver latency trace | DPC/ISR durations and module attribution | Not established |
| App overhead | CPU time, working set, wakeups, baseline versus monitoring | Not established |
The website has previously displayed a 330-to-551 FPS comparison. Its drawn frame-time traces are schematic; they are not raw capture data. Treat any individual demonstration as specific to its setup until the full test conditions and repeat runs are available.
For useful comparisons, keep the game build, scene, settings, drivers, power source and capture method fixed. Warm caches, alternate baseline/tuned runs, retain all valid runs and publish raw data. Separate security-reducing configurations from normal recommendations. Report regressions and unchanged results alongside gains.
Free and Pro
Free does not require an account. It includes core tweaks, scans, supported restore tools, hardware monitoring and selected maintenance tools. Pro adds advanced tools, guided repair, additional cleanup options and Game Sessions.
| Current plan | Price |
|---|
| Monthly | €7.99 per month |
| Annual | €59.99 per year |
| Lifetime | €99 once |
Annual billing is approximately 37% below twelve monthly payments. Check the app and checkout for current offers, taxes and renewal terms. Existing lifetime purchases retain the access promised when purchased. Payments use Stripe Checkout; the app does not handle card details. Pro is linked to the purchasing account; the app refreshes its license when you return from checkout while online.
Download integrity and code signing
Version-specific signing inventory and verification guide
Verify the release you download. The latest release is the download entry point; the version-specific inventory above records signing evidence. For an official Windows build, verify a valid Authenticode signature identifying Aurelio Avila and a trusted timestamp on the exact application and installer. A verification recorded for an older release does not establish the status of a newer file.
Windows Authenticode and Tauri update signatures have different roles. Authenticode identifies the Windows publisher and detects changes after signing. Tauri's update signature verifies update packages.
Older releases, including v1.8.0, may be unsigned. Their .sig update files do not establish Windows Authenticode signing. Check the exact version and the file's Digital Signatures tab.
To inspect a downloaded installer in PowerShell:
Get-AuthenticodeSignature -LiteralPath .\PCTweaker-Setup.exe |
Select-Object Status, StatusMessage, SignerCertificate, TimeStamperCertificate
Get-FileHash -LiteralPath .\PCTweaker-Setup.exe -Algorithm SHA256
A valid signature does not guarantee the absence of SmartScreen prompts. Microsoft evaluates file and publisher reputation separately. See Microsoft's SmartScreen guidance. Use an official distribution channel and verify the publisher when prompted.
Reviews and distribution
120,000+ total downloads estimated across the Microsoft Store, WinGet and dozens of download sites, as of October 2026. Most of that total is the Microsoft Store, which publishes no public figure; the live GitHub badge covers GitHub release assets only, a small share of it.
User ratings checked October 24, 2026. Existing feedback remains available at its original source:
- Softpedia: user rating 5.0/5; editorial review 4.5/5.
- MajorGeeks: user rating 5/5; listing and reader reviews.
The GitHub download badge counts release-asset requests, including assets used for updates. It does not count unique people, unique installations or every distribution channel. Third-party listings may describe older releases; this repository's LICENSE is the authoritative source for licensing terms.
Build from source
Prerequisites: Node.js 22 as used by CI, npm, stable Rust installed with rustup, Windows Visual Studio Build Tools with Desktop development with C++, a Windows SDK, and Microsoft Edge WebView2. See Tauri's platform prerequisites.
git clone https://github.com/AurelioAvila/pc-tweaker-app.git
cd pc-tweaker-app
npm ci
npm run tauri dev
Run the frontend and translation checks:
npm run build
npm run lint
npm run format:check
npm run check:i18n
npm run check:i18n-quality
npm run check:native-policy
Run the complete Rust suite and full check in a disposable Windows VM with a snapshot. The Free/Pro policy tests now avoid the Windows tweak adapters. Other existing tests still exercise real file operations and protected-path guards; these are not a replacement for an isolated integration environment. A temporary journal directory alone does not isolate Windows. The focused license, IPC, rollback-store and game-session tests use signed fixtures, a mock runtime, temporary stores or fake operations.
Inside the disposable VM:
npm run check
Build installers:
npm run tauri build
Artifacts are written under src-tauri/target/release/bundle/. A development build does not acquire an official publisher identity or update-signing key. Release signing is configured separately; follow RELEASING.md, treating Authenticode and update signing as separate verification steps. Never distribute a verification build as an official signed release.
The account and payment backend is in backend/:
cd backend
npm ci
npm test
Backend integration tests need a separate configured test environment. Production smoke scripts can create external state and are not part of an ordinary local source check.
The website is in site/: run npm ci and npm run build from that directory to produce its prerendered pages.
