Set Default Apps During OSD Task Sequence Not working

Has anyone had any luck setting default apps with a SCCM task Sequence? i have plenty of experience setting it on my traditional "golden" images, but i am moving to SCCM for imaging now and working on my task sequence. Just using VL media, not custom image.

The problem i am running into is that i think the dism import is working fine but either the defaults are getting reset (because i see tons of messages about that, but that usually doesn't mean anything), or somehow my import step isn't working....

Here is how i am doing it. I deployed the OS and apps to a VM, Changed the Mail app to outlook 2016 and .PDF to adobe reader, exported the default apps to xml using dism, then created a package that includes a DefaultApps.xml and a SetDefaultApps.cmd that's running Dism.exe /online /Import-DefaultAppAssociations:Defaultapps.xml but the end result is a bunch of "app defaults were reset" and edge being the pdf viewer and the mail app being the default mail program (not outlook).

I even tried Dism.exe /online /Import-DefaultAppAssociations:%~dp0Defaultapps.xml but still no workie....

really strange because i feel like i have done everything right.... the OS i am deploying is 20H2. for some reason it seems to work ok on LTSC though (using the exact same task sequence).

    Hi,

    Thanks for posting in Microsoft MECM Q&A forum.

    Please try to put it in a .cmd file and use the ~dp0 variable to get it to work.
    command line: Dism.exe /online /Import-DefaultAppAssociations:%~dp0Defaultapps.xml

    For more information, please refer to:
