Reclaim space from Windows 10 WinSxS folder

On my main PC my WinSxS folder increased to 28GB, to check it can be cleaned run the following from an elevated command prompt:

Dism.exe /online /Cleanup-Image /AnalyzeComponentStore

Result:

Component Store (WinSxS) information:

Windows Explorer Reported Size of Component Store : 9.13 GB

Actual Size of Component Store : 7.97 GB

Shared with Windows : 6.06 GB
 Backups and Disabled Features : 1.63 GB
 Cache and Temporary Data : 265.06 MB

Date of Last Cleanup : 2017-09-06 10:19:03

Number of Reclaimable Packages : 2
Component Store Cleanup Recommended : Yes

If the output indicates a cleanup is recommended, then run:

Dism.exe /online /Cleanup-Image /StartComponentCleanup

This command takes a while, but my WinSxs folder is now 7GB.
