Thanks, I tried but it didn't work. He still comes in the screen where you have to tell the network, automatic updates and users. In the last you have to place at least 1 user. The second part I didn't try yet because I don't know how to use cmdlines.txt. By the way FactoryMode I found in Windows 2003 and/or with sysprep. I try to make a clean install CD for Windows XP. Does it work in XP without sysprep?
