Hi all The last few weeks I've done loads of research about making an unattended installation of Windows7. This resulted in a pretty good autounattended.xml file. Now I've made an ISO file of windows 7 and this xml file, this is all going very well. When I boot for the first time I don't get the sysprep screen. It's not that I can't find it, but is it really necessary to run sysprep for a complete unattended install? What exactly does Sysprep do? My assignment is to install a big amount of computers. Can I do this without sysprep? Thanks for all your help! Greetz Thomas
