Is there any way to change my windows xp cd key?

[bullion416]

My friend just sold me a computer that has windows xp pro on it. He wants to use xp on the system he just built. I have a legal cd key that I got from school. Is there a way I can change the current cd key to the one that I got from school without having to reinstall windows?

I used this program. It worked like a charm.
