I'm glad to hear your "upgrade" worked! For those of you who are not sure about whether you can do a simple upgrade or will need a clean install, Microsoft has published an upgrade chart.

In general, if you're upgrading to the same "version" of Windows 7 that you had with Vista, or upgrading to Windows 7 Ultimate, you're in luck. However, any other type, like changing from 32 to 64-bit, or are coming from Windows XP, you'll need to do a custom install.
