I have a Windows 2008 R2 x64 server with service pack 1 installed. Recently I noticed that all my disk space was all used up and found that my WINSXS folder was 13Gb in size. I tried disk clean up and that only relived 456MB and used DCIM.exe but it came back telling me there were no service packs installed. This server is my WSUS server so I tried cleaning up the server through server cleanup wizard but when I go to delete Unused updates and update versions the process fails with an error. I have searched the forums and cannot find anything to work. What can I do to cleanup my WINSXS folder without deleting the contents manually which isn't recommended nor do I really want to do?
