The Dismount-DiskImage cmdlet dismounts a disk image (virtual hard disk or ISO) so that it can no longer be accessed as a disk. This cmdlet
requires either the full image path of the ISO or VHD file, or the device path.
To eject a VHD file, administrator privilege is required. Administrator privilege is not needed to eject an ISO file on Windows® 8. On Windows
Server® 2012, only an administrator is allowed to mount or eject ISO file.
