Frequently Asked Questions

TuneBit is a subscription-based Windows PC repair and optimization app with 35 powerful tools. It can fix common Windows problems, speed up a slow computer, remove junk apps you didn't ask for, stop Windows from tracking you, check your PC's health, and much more. It works on Windows 8, 8.1, 10, and 11.

TuneBit supports Windows 8, 8.1, 10, and 11 (all 64-bit). Windows 10 and 11 are ready to go — just download and run. Windows 8 and 8.1 need a free Microsoft update (.NET Framework 4.8) installed first — see our Windows 8 setup guide for easy step-by-step instructions.

No. TuneBit works entirely offline. All 35 tools run locally with no cloud dependency. The only time you'd need internet is to download the app itself or to activate your license.

TuneBit collects zero telemetry. It does not phone home, track usage, or send any data anywhere. All operations run locally on your machine.

In many cases, yes. TuneBit can speed up your startup, reduce background clutter, remove junk apps, and fix problems that slow your computer down. It won't turn a 10-year-old PC into a gaming machine, but it can make a noticeable difference for everyday use.

Yes, subscriptions automatically renew every year to ensure you always have the latest tools and security updates. You can turn off auto-renewal at any time in your account settings.

Some antivirus software may flag new or unsigned executables as suspicious. This is a false positive — TuneBit does not contain any malicious code. If flagged, add an exception for TuneBit.exe in your antivirus settings.

Yes. Before any registry modifications, TuneBit creates a .reg backup file. Before applying system tweaks, it creates a System Restore point (if restore points are enabled). You can always undo changes.

TuneBit uses the same repair tools that are built into Windows itself — the same ones Microsoft recommends. These are safe and well-tested. If a repair doesn't work, your system is left exactly as it was — nothing is forced or changed without your knowledge.

TuneBit can look up what caused your blue screen and suggest fixes in plain English. It can also run Windows' built-in repair tools to fix corrupted system files, which is one of the most common causes of blue screens. However, if the blue screen is caused by faulty hardware or a bad driver, TuneBit can identify the problem but can't fix the hardware itself.
