I've tried that Nlite & that other program (Windows unattended CD Creator) and placed the product key and created a iso and burned it, when i tried to install windows from this CD the key was not inputted, i was asked for this by the installation. The only thing i really want to do is have the product key on the CD so i don't have to type it in. If i am to use a winnt.sif file, where do i place that on CD image file so i can reburn to make bootable. I tried placing it in the i386 folder of my source image and that didn't work. I placed that and the batch file that was created using the deploy tools suggest by http://unattended.msfn.org/beginner/localsource.htm I've seen iso cds with the key on it, when you insert the CD, it doesn't ask for the key and installs. The problem is this particular winxp cd iso file i have has a pirated key on it. If there is a way i can go in the iso file of this CD and change the key to my own key, then that would be just as good. Can any of you WinXP guru's help me please? Thanks!
