Hi The1985evs,
You have definitely been around the forum long enough to know that this is definitely not the place for that type of question

. Madgamer was absolutely right in his point.
Now if you actually want to upgrade your girlfriend to XP, why don't you impress her and buy it you can probably get a pretty good deal on the internet. This place,
Now.net, has it for $49.00, and you can possibly get a student discount (if either of you are students at many listed sites.) Simply Google Discounted XP.
Once you have your legitimate copy, I recommend that you follow the instructions listed in my sig for Installing XP, they were written by our resident magician, Merlin, and will not only have XP running on her computer well, it will keep it that way for a really long time. I followed his instructions and they are fantastic.
We look forward to hearing from you once you get her software.
TTFN
