Ever since the release of Windows Vista, Microsoft began storing windows updates in a folder named Winsxs. Many of us can remember with XP and Windows Server 2003 when the Windows updates were stored in long GUID looking folders in the root of the Windows directory. Once in a while you’d go in there and just delete the folders to free up some disk space. However, with Windows 7, you can’t just go in the Winsxs folder and start deleting stuff, unless of course you want to completely hose your computer and reinstall Windows. Fortunately there are ways to perform a WINSXS folder cleanup in Windows 7 and more importantly in Windows Server 2008 R2.
Select Start, Run, and then type Cleanmgr. Click on Cleanmgr to run it
If you have multiple partitions (i.e C: and D: drives) you will need to select the drive you want to clean
Look for Windows Update Cleanup, if you don’t see it, select the System Files button. Cleanmgr will re-scan the C: partition, you will now notice the Windows Update Cleanup feature along with how much disk space will be freed up. Make sure the checkbox is selected.

Once the cleanup is finished, you will need to manually reboot the computer for space to be freed up. It will not ask you to reboot
