Clean Up the SxS Folder (WinSxS)




Use Disk Cleanup to Delete Old Updates From the SxS Folder

1. Open the Disk Cleanup tool. You can do this by typing "disk cleanup" in the taskbar and clicking "Disk Cleanup"
start diskcleanup
2. Click the "Cleanup system files" button.
diskcleanup system
3. Check the box next to "Windows Update Cleanup."

diskcleanup updates(2)4. Click OK.
Note that if you don't see the Windows Update Cleanup option in Disk Cleanup, that means there aren't any files that can be safely deleted.


Use the Command Prompt to Clean Up the SxS Folder

If you want a more thorough view of how much space the SxS folder is taking up and the option to clean up unneeded files, use the Command Prompt.
1. Launch the command prompt with admin priviledges. You can do this by right-clicking on the Windows icon in the taskbar and click "Command Prompt (Admin)."
cmd admin(2)2. Enter the command: Dism.exe /online /Cleanup-Image /StartComponentCleanup
dism
It could take a few minutes for the DISM tool to analyze the folder. When it's done, you'll see size details of the components in the WinSxS folder and, at the bottom, a recommendation to clean it up or not.
3. If recommended, clean up the folder using this command in the Command Prompt: Dism.exe /online /Cleanup-Image /StartComponentCleanup
There's another command you can use to uninstall Windows updates and service packs, which saves more space, but we don't recommend you do that, because you won't be able to uninstall any current service updates or service packs after performing this. The command is Dism.exe /online /Cleanup-Image /StartComponentCleanup
The cleanup might take some time, depending on your system and how much you're deleting, but that extra space will be worth it.
