create .reg files that contain the changes, then have the user either manually launch each .reg file or create a batch script that will automagically import all the different .reg files into there registry.

then the person just needs to reboot the PC and job done.

here is a understanding .reg files page:> http://www.windowsnetworking.com/nt/...regfiles.shtml

side note* if possible why not just use a remote desktop control app, like vnc so you can remote connect and manually make your changes?
