Funny thing about Windows. My old roommate and I both have Intel MBP. I wanted to dualboot, but was very unsure about the process, and didn't want to pay however much money. So, my roommate, who was wealthy, bought a legit copy at Circuit City or something of XP Home.
He installed it, and it worked wonderfully. I installed it and when it came time to validate the software, I decided to call it in. On the phone with the person, I originally tried lying saying I'm installing it onto a new computer since my old computer died. That wasn't allowed, so I hung up.
Now, I should mention that when you first call in, it asks you to enter in a code that is on the screen. I entered this in and it said the device was already registered or something. So I clicked on the button that said refresh (or something similar), and it gave me a new code. I entered that code in and voilà, I had a fully functioning copy of XP Home, SP2.
I guess what happened was that the original code they gave me was also for my roommate's. When I clicked on refresh (which the screen says to ONLY do if you are instructed by an operator), it gave me a completely unrelated one.
Moral of the story: if you know someone with a store-bought copy, try it out. It definitely can't hurt.
Moral of the story 2: dumb luck is a great thing.
