Removing Backup Files Created during Windows 7 Service Pack 1 Installation

For the Windows Vista Service Packs there was vsp1cln.exe (SP1) and compcln.exe (SP2) to cleanup the backup files created during the Service Pack installation. For Windows 7 Microsoft did not provide a separate cleanup tool, but instead leverages the windows-build-in DISM tool.

To remove the backup files created during the Windows 7 Service Pack 1 installation run the following command from an elevated command prompt.

dism.exe /online /cleanup-image /spsuperseded

After successful completion you should get some disk space back.
