Hello,
again I encountered another puzzle to solve:
How to install .appx packages during OS installation?
This step was neccessary because hardware vendors started to include Universal Apps for configuring their hardware specific drivers (which seems to defeat the original point of 'universal' apps). But when we try to install them during the initial setup process, the installations fails.
If we install them after the completed OS installation, it works. We tried to configure the side load option and checked whether GPOs could be at play after the completed installation, but they only come into play as soon as the computer account is moved to the configured OU. Also Windows Updates would only start installing after activation through the GPO. But as our security rules deny direct connection to the Microsoft Store, we downloaded the appropriate packages including license files from the business app store, so we should have everything we need to use the corresponding PowerShell Cmdlets.
We are wondering if there's a connection with the default installation account permissions and it not working, but weren't able to verify that as of now.
Did anyone encounter this issue and hopefully discovered a solution?
Regards,
Marco Lorenz
