Thank you, i dont have a winnt.sif file the software distribution uses a different type of script, it will process the unattend.txt file though. apart from some cosmetic registry entries what i am trying to do is get a reg key inserted before the first logon, the reason is that the SD client cannot bypass our legal notice, so i was given a reg key to enter. the other reg keys can be scripted once the install has finished. So the real question is how do i insert a reg key before windows finishes building and before it tryed to login thanks for you time and help Regards Allanv
