okay i know how to make unattended installs but ive seen some people have done ones thatll have inf files where you can add your serial as well. vmware is the perfect example. how do you do that?

a good way to do the serial numbers side of things is via a .reg file
that is imported at the first real bootup of windows

but thats just me

I second the use of a .reg file.

in the unattended section of nLite theres a space for it. theres also registry tweaks for it.
