Not sure about the 'locking' of your XP license to Vista, but I cannot see
any advantage to upgrading XP anyhow. You will be best off with a clean
install! Anyway, can you even perform an upgrade with a full version? I
thought that with previous versions of Windows, the full version would not
allow the upgrade, and advised to go back and buy an upgrade version
instead?
