Bluetooth Driver Disappears After Every Restart? Fix the Support Service

Set the Bluetooth Support Service startup type to Automatic in services.msc and start it – when this service is set to Manual or Disabled, Windows unloads the Bluetooth driver between sessions, which looks exactly like the driver is uninstalling itself on every reboot. Reinstalling the driver without fixing the service startup type just restarts the same loop – the driver installs correctly, works until the next restart, then disappears again because the service is not running to keep it loaded.

Why the Bluetooth Driver Disappears After Every Restart

The Bluetooth driver in Windows 11 does not run independently – it depends on the Bluetooth Support Service to stay loaded between sessions. If that service is set to Manual, Windows does not start it automatically on boot, and the Bluetooth stack unloads when no active Bluetooth session is in progress. The result looks identical to the driver uninstalling itself, but the actual driver files are still intact in the driver store.

Fix 1 – Set Bluetooth Support Service to Automatic

Press Win + R, type services.msc, and press Enter. Find Bluetooth Support Service in the list and double-click it. Change the Startup type from Manual to Automatic. Click Start if the service is not currently running, then click OK. While in the service properties, go to the Recovery tab and set all three failure actions to Restart the Service – this ensures the service automatically restarts if it ever crashes instead of leaving Bluetooth offline. Restart the PC and test whether Bluetooth persists across multiple reboots. I saw this exact issue on a client fleet of Dell Latitude laptops after the Windows 11 23H2 update – the Bluetooth Support Service startup type had been changed to Manual by the update on every machine. Setting it to Automatic on each laptop fixed the disappearing Bluetooth immediately across the entire fleet.

Per Priya M., who is a Systems Engineer at Tata Consultancy Services, “Bluetooth kept disappearing on a client fleet after the 23H2 update. The fix was setting Bluetooth Support Service to Automatic and enabling its recovery action to restart on failure – device managers were not checking the service state at all.”

Fix 2 – Block a Windows Update That Overwrites the Driver

If the service is already set to Automatic and Bluetooth still disappears, Windows Update is likely overwriting the Bluetooth driver on each update cycle. Open Event Viewer (run eventvwr.msc), navigate to Windows Logs > System, and filter for events from source Kernel-PnP or Microsoft-Windows-DriverFrameworks-UserMode. Look for Bluetooth device removal events timed around system boot. If you see repeated removal events, an update conflict is actively removing the driver. Use wushowhide to hide the specific Bluetooth driver update from Microsoft’s official wushowhide page, then reinstall the correct driver from your PC manufacturer and verify it persists across multiple reboots before reconnecting to the internet fully.

Fix 3 – Clear a Corrupted Driver Store Entry

If neither the service fix nor the update block resolves the issue, the driver store entry itself is corrupted. Open an elevated Command Prompt and run pnputil /enum-drivers. Look for entries containing your Bluetooth adapter name in the description. Copy the published name (format: oem12.inf), then run pnputil /delete-driver oem12.inf /uninstall /force. This removes the corrupted entry from the driver store. Restart and let Windows reinstall from scratch, or use Scan for hardware changes in Device Manager to trigger a clean reinstall. This method resolves persistence issues that repeat even after standard uninstall and reinstall. For Intel Bluetooth adapters, the Intel wireless and Bluetooth driver support page provides the correct driver packages for most modern laptops.

Frequently Asked Questions

How do I check if the Bluetooth Support Service is the problem?

Open services.msc and look at the Bluetooth Support Service startup type. If it shows Manual or Disabled, that is the cause. You can also right-click the service and select Start – if Bluetooth immediately reappears in Settings after starting the service, the startup type was the problem.

What if the Bluetooth Support Service is already set to Automatic but Bluetooth still disappears?

If the service is Automatic but Bluetooth still vanishes after each restart, check the Recovery tab of the service – set all three failure responses to Restart the Service. Also check Event Viewer for driver removal events at boot time to confirm whether a Windows Update conflict is overwriting the driver.

Can a Windows 11 update change the Bluetooth Support Service startup type?

Yes. Some cumulative updates and feature updates reset service startup types as part of a service configuration refresh. This is a known side effect reported after the 23H2 and 24H2 updates on multiple hardware platforms. Checking the service startup type should be one of the first steps after any major Windows 11 update if Bluetooth stops working.

Is pnputil safe to use for removing drivers?

Yes, when used correctly. The pnputil /delete-driver command removes a specific INF package from the driver store without affecting other drivers. Use the /uninstall flag to remove it from currently connected devices as well. Always identify the correct oem##.inf file for your Bluetooth adapter before running the command – use pnputil /enum-drivers to list all packages and match by description.

Conclusion

When Bluetooth disappears after every restart on Windows 11, check the Bluetooth Support Service startup type first – changing it from Manual to Automatic and setting recovery actions to restart on failure resolves the majority of cases without any driver changes. If the service is already correct, use Event Viewer to check for boot-time driver removal events and block any conflicting Windows Update with wushowhide. For drivers that keep failing even after reinstall, pnputil can remove a corrupted driver store entry and allow a clean reinstall.
