Default Behavior
Device Association Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Device Association Service is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If Device Association 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 DeviceAssociationService service has failed to start due to the error.
