Default Behavior

Microsoft MAC Bridge is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If Microsoft MAC Bridge fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the MsBridge service has failed to start due to the error.
