During the OOBE, Windows 8.1 will give the color-changing screen with "hang on" and whatever MOTDs it wants to give. What it's actually doing is downloading and installing updates. This is messing up my imaging workflow and I need to totally disable this. I've been banging around with unattend.xml (I do my installs via WDS) and I can't seem to stop it. Anyone see a way to stop the OOBE updates?
