I upgraded my Win10 Hyper-V vm from 1703 to 20H2. I had no issues doing that, but ran into all sorts of hell when it came to sysprep. This app, that app....I ran every PS there was out there to remove apps that broke sysprep.
So, I'm going to upgrade it again, but I'm looking for the most proper way to do so
without any apps causing issues again with sysprep. One thing I've done is make an internal network connection only between the VM and the MDT Server. I just do not want to pick up appxpackages or provisioned packages and whatever else that will cause sysprep to bomb. I spent two weeks removing an app, and another and another, ran PS's that 'removed' all of these in one click, to finally get sysprep to run; it rebooted my VM
and the admin acct was locked out. Oh, and all the apps were back.
I'd just like to know the proper way to upgrade an OS on my VM and be able to sysprep/capture it.
