Windows 8.1 and the mythical WinSxS

To see the actual size of the WinSxS folder in Windows 8.1

/>dism /online /cleanup-image /analyzecomponentstore

Backups and Cache is the actual space used by WinSxS

To cleanup the folder in Windows 8.1

/> dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
To do it on previous versions (to w7 or vista)
/>dism /online /cleanup-image /spsuperseded
After running this command its no longer possible to uninstall updates or servicepacks. But most people don’t and if you change your mind, you can always get the msi-package and still do an uninstall.
