Upgrade License Clean Install vs. Full License

    I purchased the upgrade version of Vista Business and would appreciate
    verification of what I've found:

    When doing the upgrade, it required a pre-existing installation of a valid
    O/S, like WinXP SP2. It is not sufficient to input just a license key from
    the older valid O/S, so if you ever need to re-install Vista, you have to
    reinstall the older O/S first. Ouch.

    Is that right or did I miss something?

  3. Upgrade installation keys are blocked when you start from the Windows Vista DVD

    Yes the upgrade process is different in Vista. It does not do a shiny media
    check as in XP (you didn't have to input a product key, I'm not sure what
    you are thinking of. In XP when doing the upgrade you would insert the CD
    for the qualifying OS early in the install process when prompted as proof of
    ownership).

    To install from a Vista upgrade DVD, it's designed to start the installation
    from the desktop of the installed, qualifying OS. That said there is a way
    to install an upgrade version of Vista on a bare hard drive. You still have
    to own a qualifying OS. This process doesn't remove that requirement.

    It involves doing two installs, the first one you install the version you
    have a product key for on the bare drive, but don't enter the product key.
    Then you run an upgrade on that with the same DVD, and in that second
    install you enter the product key. Here is an article on how to do it.

    To avoid the hassle of reinstalling the qualifying OS or doing a double
    install, if something damages the Vista installation that you can't repair,
    image the system using something like Acronis True Image Home version 10
    saving the image on an external hard drive.

    Thanks to Val and others that responded.

    I'd figured out that leaving the registration key field blank was a method
    to work-around the problem, but was concerned about the embedded warnings
    and what would happen when 30-days were up. The article covers that -- run
    the Vista upgrade again, effectively "upgrading" the just installed clean
    upgrade so it can be activated. Only from the minds of Redmond, I suppose.

    Other upgrade paths I have seen allow just inputting a valid license key
    from a previous version or temporarily inserting the previous version
    CD/DVD. If my memory serves me, Frontpage was one of those products, and
    the upgrade would work even if the previous version was also an upgrade.
