Everything I've read and heard tells me that I should be able to perform an upgrade from Windows 2000 Pro to Windows XP Pro instead of a clean install. One blogger went as far as to say that there are only a few files that are different between the two OS's, although I highly doubt that.
So why when I put in my Win XP Pro install CD did it tell me that it cannot upgrade from Win 2K pro to Win XP pro? I also tried booting from the XP pro install CD and it didn't even have any options for upgrading.
