    Hi All,

    What is the difference between Windows Vista Home Premuim Upgrade DVD
    and Windows Vista Home Premuim Upgrade DVD OEM which is advertised cheaper
    than the Retail versions in the Stores?

  2. There is no such thing as "Vista Upgrade DVD OEM media".
    ALL "Vista OEM media" is licensed according to the Windows OEM
    license, while ALL "upgrade media" is licensed according to the
    Windows Upgrade license. OEM keys will NOT work with "upgrade media",
    nor will "upgrade media" work with "OEM" keys.

    Obviously, you misunderstand the meaning of "Upgrade media", as well
    as the meaning of "OEM media".

    This is because of the confusion caused by many dishonest retailers
    who consistently advertise "OEM media" as "Upgrade OEM" or mix the two
    terms to try to hood-wink their less-knowledgeable customers.

    OEM media will NOT do an in-place "upgrade" of a previous version of
    Windows. It MUST ALWAYS be installed "clean".

    "Retail Upgrade media" will perform "in-place upgrades" from a Windows

    Simple as that.

    The Express Upgrades are OEM are they not?

  4. There is a large difference between "Express Upgrade (OEM)" and
    "Upgrade OEM". The first one exists, while the second one does not.

    Hi Donald L McDaniel and All,

    Example of what I mean are with the links:


    Windows Vista Home Premium 32-bit DSP OEM DVD


    Windows Vista Home Premium Upgrade - DVD

    Same Store or Dealer.

    Do Hotfixes come from Microsoft Windows Update for both? Do you get
    Hotfixes or downloads from Microsoft for the OEM Version, as you do from the
    Upgrade version? This is what I am talking about.

    Once installed both versions are identical (with updates/hotfixes), but the
    OEM version is for a new computer installation or at least a system without
    a previous OS installed and is not considered an upgrade. The non-OEM
    version requires you to have either a version of XP or Win 2000 already
    installed on your computer and is considered an upgrade. The only other
    difference is that MS does not provide troubleshooting support for OEM

    Also the OEM version is sold separatly for 32 bit and 64 bit systems and the
    license terms certainly implay that it can installed on only one system
    which can have minor upgrades only just like the prebuilt systems you get
    from the manufactuers where the product Key sticker in on the case since the
    license is only for that system.
    I have read posts that you can do and have done inplace upgrades of
    existing 32 bit systems using the OEM version.
