    Windows 10 10074

    install size Update vs Clean


    Running on a 128GB SSD card, the Windows directory is around 50 GB's. Not much room left for anything else. Windows 8 was significantly less.

    After every update I delete the $Windows~BT directory and the Windows.old directory to free up about 8GB's.. but it's not enough.

    Would a clean install remove a lot of the junk in the Windows directory or is that always going to be the size?

    I'm going to take a stab at this and say you should save some space by doing a clean install. If I recall I used much less space when I did a clean install yesterday with build 10074.

    What on earth do you have in your Windows folder? I have Build 10074 installed on three machines, this laptop I am using at the moment has the biggest Windows folder, about 21 GB.

    1. Delete everything in C:\Windows\Panther, those files were used during installation and no longer needed
    2. Delete everything under C:\Windows\SoftwareDistribution\Download. Windows stores all downloaded updates.
      NOTE: Don't delete while Windows Updates is running.
    3. From Admin Command prompt, run: dism /online /cleanup-image /startcomponentcleanup to reduce the size of WinSxS folder

    What's the size of your Windows SxS folder?

    Ahhh, seems like a good time to research DISM.exe and all the benefits it provides!
    I posted a few days ago that I whittled 10GB off my Win8.1 Windows SxS folder using DISM.
    Brink has posted information about using it but I think the info you're looking for was posted back in the Win7 forum.
    DISM will analyze SxS folder, advise whether it should be cleaned, and then provide a means to clean it.
    Mine dropped from 16GB to 6GB.............. YMMV......

    Close to 15Gb for me too. I agree with all above, clean install is the best option.

    I've violated the clean install rule when there was no ISO available (10041?) but you can still save 9 or10GB of space by cleaning your Win SxS folder. Did you analyze yours to see if it can be reduced?

    Nice. I'll research a bit about it too.
