Default Behavior
Device Association Service is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Device Association Service is started, it logs on as LocalSystem and running in a shared process of svchost.exe. If Device Association 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 DeviceAssociationService service startup failure.
