How to recover disk space in WinSXS folder

The WinSXS folder contains copies of installed updates for Windows and cannot be moved to another drive. This folder can grow quite large, but there is a way to shrink it if you have installed Service Pack 1 (SP1) by cleaning up and deleting unused updates.

To do this:

1. Start an Administrator mode command windows;
   - Click the 'Start' button and 'CMD'
   - Right-click top entry 'cmd.exe' and select 'Run as Administrator'
   - Click 'Yes' to the security warning
2. Now just type the following command
   - dism /online /cleanup-image /spsuperseded
3. This will take a few minutes to complete, but once done you should have reclaimed several GB to storage.
