Default Behavior

Bluetooth Audio Gateway Service is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Bluetooth Audio Gateway Service is started, it logs on as NT AUTHORITY\LocalService and running in a shared process of svchost.exe. If Bluetooth Audio Gateway Service fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the BTAGService service startup failure.

Dependencies

Bluetooth Audio Gateway Service cannot be started, if the Remote Procedure Call (RPC) service won't start.
