    I have just baught the Vista Ultimate Upgrade for my new system I am putting
    together. I baught a new E6600 processor and would like to try my first
    64bit operating system. My question is if I dont like 64bit can I format and
    do a install of the 32bit all with the same key license? I was reading a
    minute ago that its possible with the retail full but is it possible with the
    retail upgrade?

    Hi William,

    Yes, you can install either with your Product Key. I would recommend that
    you do not activate the 64-bit installation unless you are sure you are
    going to keep it. This way if you revert to 32-bit, you can activate over
    the 'net rather than the lengthier phone call.

    By the by, the upgrade version needs to start from within an existing,
    qualifying OS. So, you'll either have to install XP/2000 first, or install
    Vista w/o the Product Key as a clean install, then again with it as an
