It's x64. Image number is 1 I've tried various versions of the autounattend file but it doesn't seem like it's being read at all. I'll just use the SetupComplete.cmd instead.
Forgive my ignorance, i do a lot of PC Building for a company i have disks for almost every version of windows that will allow you to put any serial for that version of windows in.. will this do the same? im unfortunately not very familiar with scripting
