Hi I have found this really neat site. http://unattended.msfn.org/ My question is if I use nlight to make my install disc would I open up an iso editor and add the files I need to, to the iso like for example. If I was to use this tweak http://unattended.msfn.org/xp/hkcu_registry.htm Is this what I will do? I open up the iso file in nero and then I add a folder called $OEM$ add the files cmdlines.txt and regtweaks.reg in that folder. Well I hope you understand what I'm saying if you don't please let me know.
