Free up more space

If you’re aching for more space on your server or workstation, use this command to remove all uninstallfiles related to servicepack1 on Windows Server 2008 R2 and Windows 7.

dism /online /cleanup-image /spsuperseded /hidesp 

For an offline WIM-image,

dism /image:wimfile.wim /Cleanup-Image / spsuperseded /hidesp.

/hidesp option removes SP1 from the “Installed Updates” section of Programs and Features, to ensure that users do not try to uninstall the service pack.

After doing this maneuver on a Server 2008 R2 my winsxs went from 12.12GB down to 6.82GB. Not a real true value though since winsxs contains mostly softlinks, but still an indication.
