    Huge DriverStore and Huge WinSxS Directory

    I noticed a large increase in my Windows Folder it is around 23.7 GB 5-6 GB larger than normal. I keep a close eye on files sizes as this is on a 64 GB SSD.
    After some searching around and making sure there are no downloads or restore points I ran CCleaner which I use religiously and windows cleaner with all options turned on. Still no luck.
    However I found what I think are the culprits.
    One. Windows\System32\DriverStore =8.06 GB to me this seems huge
    Two. Windows\WinSxS = 6.83 GB including 22,135 Folders with 92,138 files. Again seems excessive.
    Are these numbers excessively large?
    And is there anything I can do to reduce or remove them.
    Thanks any advice is greatly appreciated.

    On my Win 8.1 Pro X64 system, DriverStore is 1.7GB. On my Win 10 X64 system it 780MB.

    8.06GB is extreme for sure.

    As for WinSXS, see here: How to see the actual size of the WinSxS folder in Windows 8.1

    Edit: Looks like displayed verses actual is a lot closer than I expectd. I was under the impression WinSXS had lots of hardlinks in it and not so many actual files, I was wrong:

    C:\WINDOWS\system32>Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

    Deployment Image Servicing and Management tool
    Version: 10.0.10049.0

    Image Version: 10.0.10049.0

    Windows Explorer Reported Size of Component Store : 9.71 GB

    Actual Size of Component Store : 9.40 GB

    Shared with Windows : 7.98 GB
    Backups and Disabled Features : 999.95 MB

    Just found this:
    After running DISM with the “/ResetBase” parameter you cannot go back and uninstall previously installed updates…
    Not sure how much of a concern this should be.
