    I am working on a universal vista dvd. One thing I wanted to find out, is whether or not it is possible to enable the upgrade feature during setup, even though the product key hasn't been typed in.

    if that doesn't work, I know there are universal deployment product keys, would any of those enable the upgrade feature?
