Default Behavior

Connected User Experiences and Telemetry is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Connected User Experiences and Telemetry service is running as LocalSystem in its own process of svchost.exe. If Connected User Experiences and Telemetry fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the DiagTrack service has failed to start due to the error.

Dependencies

Connected User Experiences and Telemetry cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.
