Hey Folks! Just bought Windows Vista this past weekend and upgraded my WinXP Pro. Since my copy of WinXP was installed as non-SP'd, my 250gb HD had to be split into two partitions. I decided to do a clean install from the upgrade CD since I was required to do a clean install anyways. Long story short, when I went to activate, the product key wasn't valid because the one I have doesn't support a clean install. The question I need answered is, does anyone know if there's a way to upgrade my copy of Vista from an upgrade copy to a full version?
