Thanks for all of your responses. They help frame the question. nLite by design assumes that you are installing Win XP on a foreign computer, otherwise you would not need special drivers to install it.
However, if you cannot activate it because it is now running on foreign equipment, why use nLite?
I thought buying an OS means you can run it on any computer, albeit only one at a time. But it seems MS tries to tie it to only one computer for life.
