You can create a default app assofications xml file in a reference computer and apply it to the image.

Reference computer.

Dism /Online /Export-DefaultAppAssociations:"F:\AppAssociations.xml"

Mount the sysprepped wim file.

Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows" /MountDir:C:\test\offline

Import the settings to the mounted wim file.

Dism.exe /Image:C:\test\offline /Import-DefaultAppAssociations:F:\AppAssociations.xml

Unmount the image.

Dism /Unmount-Image /MountDir:C:\test\images\install.wim /commit
