DISM: Unmount and Clean up a Wim Image

dism /get-MountedWiminfo

Check the Status.

dism /remount-wim /MountDir:<mountDir>

This command will recover an orphaned Wim mount directory.

dism /unmount-Wim /MountDir:<mountDir> /commit

Once you are done with Servicing the Wim Image, you can unmount the image from your machine.

dism /cleanup-wim

The /Cleanup-Wim command is only used if there is any issue with the mount points, that means when any of the mounted images are shown as in the “Invalid” state. You can run the cleanup command to delete these abandoned resources at the corrupted mount points.

  1. Use the dism /unmount-Wim /MountDir: /discard command in case of you receive this message:

    An attempt was made to commit an image that was mounted for read only access. T
    his is not valid. To commit an image, mount it without the read only flag set.
