    Thanks Brink for a so quick reply. But it doesn't work on my system. Cleaning the Components Store is desperately locked until next updates bundle is sent by Microsoft. Note that I clicked on the link in the mail, and immediately came back here. Did something go wrong? If you could resent it?
    Thks, B.B.

    The link in the reply notice email sent by us (the site) includes a link to the thread the reply is for so you can post a reply if wanted.

    The component store will never be completely empty. You will only be able to clean out what is no longer needed.

    I know it will never be completely empty (happily!). After a clean reinstall from my DVD (it's an industry version of Win 8.1 Pro 64-bit) the first WinSxS size is about 14 GB. Running the full sequence I described previously gives me the following results:
    Windows Explorer Reported Size of Component Store : 5.95 GB
    Actual Size of Component Store : 5.87 GB
    Shared with Windows : 4.95 GB
    Backups and Disabled Features : 607.96 MB
    Cache and Temporary Data : 337.28 MB
    Date of Last Cleanup : 2019-08-22 12:58:42
    Fine, isn't it?
    I simply want to unlock the Dism /online /cleanup-image /startcomponentcleanup process. I also run it with the resetbase parameter, which makes me unable to remove updates, ok. No logical reason to block want I want to do.

    That sounds about right for the size.

    Yeah, you would only want to use the resetbase parameter if you wanted to reduce the size some more at the sacrifice of no longer be able to uninstall updates.

    I would simply explain why It's so worrying me. My OS is on the first partion of my first drive. Alone! I want to keep its size as small as possibel Libraries are my second drive, as well as the Temp folder, the index database, the SoftwareDistribution folder, the Fonts folder, my own softwares (first partition, too). The WinSXS folder is compressed, NOT the whole Windows folder. Goal of the game: reduce the access time of the reading heads of the drives, to get the maximum available speed while reading any required file. Don't forget that decompression time of the hard-linked files in the WinSxS folder is ridiculous wrt time lost in mechanical components movements.

    I understand.

    The best way to improve performance for this would be to have Windows 10 installed on a M.2 drive (best if supported) or a SSD.

    My understanding is that the WinSxS is just a respository store - not a required read? it's not accessed unless a deployed file needs to be repaired - or am I missing something?

    Hi Superfly
    Yes, you are a bit misunderstanding... The WinSxS folder contains most of the operating system files, in multiple versions, for compatibility reasons with all the Windows subsystems as well as for the files required by the softwares you have installed. My WinSxS folder is compressed. Not to simply gain space, but to reduce the access time of the reading heads, in a well defragmented drive - I don't intend to use SSD. In a normal view of any Windows folder, all the file names are in black, but if I select "Show encrypted or compressed NTFS files in color" most of the files appear now in blue. It means that these "blue files" are not really there, but what I'm seeing are "internal shortcuts" to versions of the files contained in WinSxS. Microsoft calls this a "hard-link". It's why it's so important to keep the WinSxS folder in good health, and surely not trying to delete files looking like duplicates. All these "duplicates" are hard-links to a single file, may be with multiples versions/sizes stored in WinSxS.

    Second part of the path because the box is not expandable.
