Default Behavior

Connected User Experiences and Telemetry is a Win32 service. In Windows 11 it starts automatically during the operating system startup. Then the Connected User Experiences and Telemetry service logs on as LocalSystem and running in its own process of svchost.exe. If Connected User Experiences and Telemetry fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the DiagTrack service startup failure.

Dependencies

Connected User Experiences and Telemetry cannot be started, if the Remote Procedure Call (RPC) service won't start.
