This is the embarrassing part… I don’t have a Windows 7 unattend.xml file, nor do I know how to create one or where to place it. Sorry, don’t bash too hard on me.
Edit: I’ve created one, but I’m positive it’s not correct, and again I don’t know where to place it. I’ve also done a ton of research on this. Submitting a post on any forum is my last resort.
