PC Tweaker

A week after following a Windows tuning guide through a dozen hidden settings, nobody remembers which one broke the printer. On Windows 10 and 11, PC Tweaker explains each change before it runs and names the registry value or Windows service it touches. Supported settings save their earlier state, and a change history lets you roll them back.

The controls are sorted into gaming, privacy, interface, performance and maintenance. A ready-made profile can switch on a whole set at once. Settings that affect the whole machine carry an Admin label because they need administrator rights. Around the tweaks sit a health score, a driver list and other system tools, and Repair runs the checks built into Windows (DISM and SFC). The site warns that files removed by cleanup cannot be brought back and that a restore does not replace a full backup.

The privacy policy says tweaks and hardware readings stay on the device and that the app runs no behavioural analytics. Its source is public on GitHub under the maker's own source-available licence, and the site says installers are code-signed. A separate Uninstaller app from the same maker shows how risky a removal is and which command will run. Afterwards it scans for leftover files and registry keys and logs each removal with the disk space it freed.
