New computer owner wants to change registration name

[new2me]

When I gave my computer to a friend I installed his XP Pro upgrade package but did not delete the original windows operating system first. The upgrade installer did not ask me for user info so now my name is still on everything. How can I replace my data with the new owner's data?

I did a quick google search on change windows xp registration name and this was the information that came up.
