Default Behavior

Mup is a file system driver. In Windows 10 it is starting by the operating system Boot Loader as a part of the driver stack for the boot volume. If Mup fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Mup service has failed to start due to the error.

Dependencies

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