If AppID Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the AppID service has failed to start due to the error.

Dependencies

AppID Driver cannot be started under any conditions, if the FltMgr service is disabled.

While AppID Driver is stopped, disabled or working incorrectly, the following services do not start:
