Default Behavior

Bluetooth Support Service is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Bluetooth Support Service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Bluetooth Support Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the bthserv service hasn't been started.

Dependencies

Bluetooth Support Service can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

Restore Default Startup Configuration for Bluetooth Support Service

2. Save the Win8_bthserv_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The bthserv service is using the bthserv.dll file that is located in the %WinDir%\system32 folder. If the file is corrupted or deleted, you can put it back in there.
