    WIM larger after removing built in apps


    I removed all the built in apps but windows store from my wim file and I was expecting it to be smaller. Can someone explain and is the a command in powershell to compress the wim when I save?

    You could use dism++

    New-WindowsImage -CapturePath C: -ImagePath D:\WHATEVER.wim -name "SOMETHING" -Verify -CompressionType max

    If you are just unmounting, I don't think you can specify compression. You can if you are capturing or exporting to a new wim.

    You can use dism++ to export - it has an easy gui. Alternatively, wimlib has an optimize function:

    Oookay... That's makes sense. I'll give exporting a try.

    If you want to use Powershell as SIW2 said you can't compress using Dismount-WindowsImage (for some unknown reason - some of these Powershell wrappers are a bit simplistic I think.).

    What you can do is Dismount the image (to save your changes) and then use Export-WindowsImage to compress it.

    You can't just export it without dismounting it first afaik.
