Diagnose • Repair • Restore Windows Bluetooth, Audio, and Microsoft Phone Link
Windows Bluetooth PhoneLink Doctor is a Windows diagnostic and repair utility that automates many of the most common Bluetooth, audio, and Microsoft Phone Link troubleshooting steps.
Instead of manually restarting services, navigating multiple settings pages, or guessing which microphone or speakers Windows is using, the tool performs automated checks, attempts safe repairs, records diagnostic logs, and guides you through selecting the correct devices when needed.

- Microsoft Phone Link diagnostics
- Windows audio service verification
- Simple RUN / RESET workflow
- Progress window during repairs
- Diagnostic log generation
- Opens the Windows Sound Control Panel (
mmsys.cpl) for manual audio selection - Smart restart recommendations (only when appropriate)
