Default Behavior

The Mup service is a file system driver. In Windows 8 it is being loaded by Boot Loader before Kernel initialization. If Mup fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Mup service hasn't been started.


All the services listed below will not start if Mup is disabled:

Restore Default Startup Configuration for Mup

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_Mup_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The Mup service is using the mup.sys file that is located in the %WinDir%\System32\Drivers folder. If the file is corrupted or deleted, you can put it back in there.
