Bit of a necro bump but has anyone tried this with 1803? I had to revert to running the langpack installs with dism in my postoobe script.
The language packs fail to install during setup, and fail the upgrade. Might have something to do with how they restructured the upgrade process... Works ok from my script but I dont like how there is now a 6-8 minute wait to complete the install when the screen is sitting at "100%" status...
