The desktop guide

Start with understanding.
Then change one thing.

Installing Qwerty Tweaks does not apply a batch of settings. You stay in control of what changes, and when.

No account, activation or website sign-in is required for the desktop app.

Requirements and compatibility

Windows 10 or 11, 64-bit. The published executables target x64 Windows, not macOS, Linux or a native ARM build.
Administrator rights. The app requests elevated permissions at launch to change system settings.
About 263 MB installed. Allow additional room for the downloaded installer and temporary extraction.

Settings and live sensor readings depend on hardware, drivers and Windows build. Some settings have explicit availability checks and are marked unavailable when those checks fail. Not every setting has a compatibility probe, and a supported Windows version does not guarantee every setting or sensor will work.

Choose installer or portable

Installer: Use this for a regular install. It adds Start Menu and desktop shortcuts and replaces an existing install at the same path.
Portable: Use this to run without installing into Program Files. Preferences, logs and saved-value history still use your user profile; portable does not mean no data is written.

Both builds have the same settings and require administrator rights. Choose your download.

First launch: make one deliberate change

Check the Overview. Review the hardware Windows reports and the available live readings. A missing temperature is not a zero-degree temperature.
Open a settings category. Read the setting's description and risk label. The full catalog helps you find the right category.
Change one setting at a time. Review any warning, test your normal workload, and restart if the setting requires it.
Keep only changes that help your use. Do not chase the app's score: it is not a performance measurement and does not promise an FPS increase.

Risk labels and recovery

Safe. The app applies these without the extra risky-change confirmation. The label is not a guarantee of no side effects.
Moderate. The app asks before applying unless you disable that confirmation in Settings. Read the possible trade-off first.
Dangerous. The app always asks and attempts a Windows restore point before applying. These can affect stability or data.

A restore point attempt can fail, and a checkpoint is not a backup of your personal files. Keep important data backed up separately. No performance improvement is guaranteed. Read the terms.

Revert a setting

Use the setting's switch or revert control in the app. When prior values were saved and the change was confirmed, the app uses that record to restore them. If a change predates saved-value tracking, or the app could not confirm what changed, reverting can use standard Windows values instead. Exact restoration is not guaranteed in those cases.

Read the app's result message. Avoid resetting all app data while you still need saved-value history. For a wider recovery, the Restore points page can list and manage Windows checkpoints; a Windows rollback affects more than a single setting.

Tools alongside the settings

Live readings: Usage, clocks and temperatures where sensors are available. Missing readings are reported, not invented.
Startup manager: Inspect entries that launch with Windows and disable them without deleting the underlying program.
Restore points: Create, list, roll back or delete Windows checkpoints. Review the consequence of a system rollback first.
Driver updates: Review applicable updates offered through Windows Update. Availability depends on Windows Update and this PC.
Cleanup: Review the scan and choose what to remove. Removing files is different from reverting a setting; do not assume deleted files can be recovered.
Saved values and logs: Review what the app keeps locally and export logs when reporting a problem. Local data details.

Update without starting over

Run the new installer over your existing installation. It replaces the app at the same path and keeps preferences in your user profile. For portable, replace the executable with the newly downloaded one.

The app's update check needs a configured feed; do not assume it will fetch a new release automatically. The changelog lists the release notes that have been preserved.

Verify the file before running it

The published installers are unsigned. Windows may show an unknown-publisher or SmartScreen warning. Do not disable security software to bypass it. You may close the warning and choose not to run the file.

The download page checks parts and, when available, the joined file's SHA-256. It reports which checks actually happened. Compare your saved file with the matching full checksum on the download page, using PowerShell's Get-FileHash or the command prompt's certutil -hashfile.

A matching checksum detects a changed or incomplete transfer. It is not a malware scan or proof of publisher identity: the checksums and installers are served by the same website. If the digest differs, do not run the file; delete it and download again.

When something does not work

A setting is unavailable: Read the reason the app gives. Windows build, hardware and driver support vary; do not force a blocked setting.
A temperature is missing: Sensor access is hardware-dependent. Optional CPU sensor support can need PawnIO. Read what touches the network before installing anything optional.
The download did not finish: Use the status beside the download button, check your connection and retry. A mismatch must not be worked around.
Report an app problem: In Settings, use Export logs. Include what you changed, what happened, your Windows version and hardware. Do not paste passwords or sensitive files.

Contact the developer

Sending the website contact form requires a website account. The desktop app does not. Password reset by email is not available.
