I can run the install unattended "builds" in a virtual PC which is very nice. It just takes a while to get through the normal windows setup to the point where I may or may not get an error related to my batch_file.cmd. Is there a way to test this file without going through the entire windows install to do it?

Yes, put everything from \$OEM$\$1\install\ to C:\install\ and manually execute your batch file.

Thanks for the reply... that's what I've been doing. I thought there might be some way to do so automagically via some series of commandline switches.
