<p>If you want to play it legit an extra copy of Windows XP will run you $25 if you’re a student at Chicago. See [url=<a href=“Information Technology Services at UChicago”>Information Technology Services at UChicago]this[/url</a>] for details.</p>
<p>If you don’t care about playing it legit there’s nothing stopping you from using the Windows XP CD that came with your original computer, or borrowing a copy from your friend. If the product doesn’t activate you can call MS and tell them any old story (“I’m installing it on my new computer and throwing out my old one”) and they’ll give you a new activation code.</p>
