Default Behavior
Bluetooth Support Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Bluetooth Support Service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If Bluetooth Support Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the bthserv service has failed to start due to the error.
