Windows 2008 R2 and Windows 7 are using a lot of space, most of this space is used by the WINSXS folder. WINSXS folder actualy doesn’t use this space but it hardlinked to DLL files of the system.


After installing a Servicepack you can cleanup the folder using the following command: DISM.exe /online /Cleanup-Image /spsuperseded
