I'm currently doing my first custom unattended Windows Seven DVD creation. I used WAIK with a retail Windows Seven DVD and created a "AutoUnattend.xml" file thanks to WSIM.
Aiming to have a zero-interaction install, I wish to skip serial input, getting the OEM serial contained into the computer.
My project manager says this serial is contained in a chip in the computer and Windows install wouldn't bug me asking for a serial. But it keeps asking me for it.
I tried several ways, using "Microsoft-Windows-Setup\UserData\ProductKey" and/or "Microsoft-Windows-Shell-Setup\ProductKey", removing one of them, leaving them blank, editing "ei.cfg" file to change "Channel" from "Retail" to "OEM". Nothing worked and I'm not sure doing this is legit.
Did you encounter this kind of problem? How did you get rid of it? Is it doable using an unattend file? Does the problem come from using a retail DVD to get an OEM key?
