Hello All - I used SIM to build a basic unattend file named simpleUnattend.xml. I then installed Vista from a network share using the simpleUnattend.xml and it installs fine. Now I'm trying to run sysprep /generalize and always get the GUI. I get the GUI with any combination of switches even passing it the simpleunattend.xml file. What am I doing wrong? Am I missing something in the unattend.xml? Thanks in advance! Hai
