Hello,
My compuer I found out is a little confused right now. When building my new computer, I dual boot between Win 7 and Win XP Pro.

My friend had a copy of xp Pro, while my old PC was XP Media Center Ed. And since I kept my old HD and didn't quite work right as a slave drive... We used his XP pro with my product key.

Now Winders media player won't upgrade to version 11 only version 10. Any ideas on fixing this or windows?
