How to Clean Up the Winsxs Folder in SBS 2011 RRS feed

  • Question

  • SBS 2011 Essentials SP1.

    Our system drive (C:) is 60GB and running out of space.  I notice that the winsxs folder is 25.5 GB.  What is this used for and how can I clean it up (reduce its size)?  Thanks for any help.

  • Hi,

    This directory contains the rollback files for windows updates and causes often space issues.

    I know two ways to clean it up , depending on the Windows version you are running:

    <run in a command-prompt with admin rights>

    Method 1: DISM.exe /online /Cleanup-Image /spsuperseded

    Method 2: VSP1CLN.EXE


    Can you try both methods without any risk , if you don't have the corresponding Windows-version it will simply not run.

    If one method works you don't need to run the other.
