Clean up Winsxs on Windows 2008 R2 after SP1 install

www.happysysadm.com/2011/06/clean-up-winsxs-on-windows-2008-r2.html


The procedure is the following:

 



        

  •     
    Install Windows Service Pack 1 then ...

        

    •     

  •     
    Start and elevated command prompt (run 'CMD' as administrator) and ...

        

    •     

  •     
    Run the DISM command, which replaces the old VSP1CLN and COMPCLN we used on previous Windows versions: DISM.exe /online /Cleanup-Image /spsuperseded

        

    •     

  •     
    Wait 10 minutes before the task completes ( it ends with “Service Pack Cleanup operation completed. The operation completed successfully”)

        



Normally you should have been able to reduce the Winsxs folder size by 1 or maybe 2 GBs, sometimes more. Saved space may vary a lot.



 

Just know that after using DISM you will not be able to uninstall the Service Pack 1 anymore.



 

Let's have a look at the used switches for DISM.exe:


        

  •     
    The /online switch tells DISM to work on the running OS installation

        

    •     

  •     
    The /spsuperseded option removes the backup files created during installation. 

        


Optionally you could use the /hidesp option which will remove SP1 (KB976932) from the “Installed Updates” section of Programs and Features, to ensure that users do not try to uninstall the Service Pack.
