Frequently Asked Questions

TuneBit is a Windows PC repair and tune-up app that puts 19 useful tools in one small program. 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 19 tools run locally with no cloud dependency. The only time you'd need internet is to download the app itself or to visit the purchase page for a Pro/Tech upgrade.

TuneBit collects zero telemetry. It does not phone home, track usage, or send any data anywhere. All operations run locally on your machine. The hardware fingerprint used for Pro licensing is a one-way hash stored locally — it never leaves your PC.

Yes. TuneBit is a single portable .exe with no installer and no external dependencies. Copy it to a USB drive and run it on any compatible Windows machine.

If your PC is slow, freezing, crashing, running out of space, getting blue screen errors, or just not working the way it used to — TuneBit can help. Start with the free Health Score to see exactly what's going on with your computer.

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. TuneBit creates a safety backup before making any changes to your system. If something doesn't work the way you expected, you can undo the changes.

The free version includes 8 basic repair utilities, full hardware inventory (7 tabs including SMART data), health scoring, blue screen analysis, event log viewer, security audit, disk space analyzer, and battery/power analysis. These are fully functional — not time-limited demos.

No. The free tier is permanent — it never expires or degrades. You can use TuneBit Free forever. Pro and Tech are optional upgrades for users who need the additional action-oriented tools.

Yes, the free version can be used in any context — personal, business, or professional. However, exported reports will include a “Generated by TuneBit Free” watermark. For professional client-facing work, we recommend the Tech license which removes watermarks and unlocks all tools.

No. There are no ads, no pop-ups, and no nag screens. Pro sections show a subtle upgrade banner explaining what the feature does, but nothing interrupts your workflow.

Both unlock all 19 modules. The difference is licensing: Pro ($19.99/yr) is locked to one PC via hardware fingerprint — ideal for home users. Tech ($199.99/yr) is a floating license with no hardware lock — use it on any client PC, perfect for IT techs and repair shops.

Pro licenses are locked to a specific PC using a hardware fingerprint (a hash of your motherboard, CPU, and Windows installation). If you upgrade a single component (like adding RAM or swapping a drive), the license still works — we use 2-of-3 matching so one hardware change is fine. If you get a completely new PC, contact us for a re-activation.

Your app continues working but Pro/Tech features lock back to Free tier. Your data, settings, and any reports you've already exported are never lost or deleted. You can renew at any time to restore access.

Yes. Contact us and we'll credit your remaining time toward the new license tier.

Yes — 30-day money-back guarantee on both Pro and Tech licenses. If TuneBit doesn't meet your needs, contact us for a full refund.

After purchase, open TuneBit and go to Settings. You'll see your Hardware ID and a text field for the license key. For Pro: send us your Hardware ID and we'll generate a key locked to your machine. For Tech: paste the key you received at purchase — it works immediately on any PC.

Tech licenses work on any PC automatically. For Pro licenses, if you've changed most of your hardware (new motherboard + new CPU), contact us for a re-activation. Single component upgrades are handled automatically by our 2-of-3 matching system.

Contact us with your purchase email and we'll re-send your license key. Your key is tied to your purchase record, not to a specific download.

No. Pro licenses use hardware fingerprinting, not Windows activation state. After a clean install, just enter your key again. Tech licenses work everywhere regardless.

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.
