Happy Friday everyone.
Need help and i think i have reached the end of google. I have a request to do a post IPU OS customization. At this point i am having an issue with a wallpaper. I am overwriting an image file "C:\Windows\Web\Wallpaper\Windows\img0.jpg" which is set to Microsoft during an upgrade, but that does not change the wallpaper. I can see an older image cached in %AppData%\Roaming\Microsoft\Windows\Themes\CachedFiles\CachedImage_2560_1440_POS4.jpg" Deleting that file does nothing. However if i run shell:::{ED834ED6-4B5A-4BFE-8F11-A626DCB6A921}\pageWallpaper it opens UI and sets the wallpaper to the correct image. I am stuck and for some reason not able to run that command from a cmd or PS or any other way from a task sequence. Can someone please help me to figure out how to run this command from TS? Or maybe there is something else i can do? Thank you for the help.

    Hi, @Michael Farber
    Thank you for posting in Microsoft Q&A forum.
    You may try to mount the install.wim from the install media and remove the image files from \Windows\Web\4K\Wallpaper\Windows and also replace img0.jpg in \Windows\Web\Wallpaper\Windows with your own custom one. Then dismount and save the wim and deploy the OS upgrade using that instead.

    Here is the reference:

    AllenLiu,
    Thank you for offering an alternative solution. However alternative is not an option at the time.
    I am trying to understand why a command working from a cmd as a system manually does not work from a task sequence?

    Thank you.

    Hi, @Michael Farber
    Do you add "cmd.exe /c" before your command in the task sequence like below?
    cmd.exe /c shell:::{ED834ED6-4B5A-4BFE-8F11-A626DCB6A921}\pageWallpaper

    And if it fails, what's the error message in smsts.log?

    It does not fail. Just does no refresh the windows background.
    Thank you

    Hi, @Michael Farber
    I see you have asked in another thread, you mentioned you are running the script as a package or as a package from the task sequence, so have you checked the execmgr.log for more details?
