    product keys


    Hello
    I noticed on both my desktop and laptop that product keys for Win 8.1 Pro with media center are different from the original Win 8 ones before I upgraded through the store.
    Does this mean that I can use this new key to install Win 8.1 pro with media center and the DVD I created from the 8.1 Pro iso file?
    Thank you
    Peter

    Hello Peter,

    The product key for Windows 8.1 Pro w/WMC can only be used to add WMC back. It cannot be used to activate Windows 8 or 8.1 with.

    You would need to install Windows 8 first, activate it with your Windows 8 product key, then add Windows 8.1 Pro w/WMC using the "I already have a product key" option in Add Features.

    Hope this helps,
    Shawn

    I usually say things that are misleading. If I may, I would like to clarify something.
    WMC aside, and speaking only about Win 8 and Win 8.1 is it true that the Win 8.1 dvd cannot be installed and activated with the new product key which is on Win 8.1?
    I would then use Win 8 then the store etc.
    Really sorry about the redundancy but I felt the emphasis was on the WMC which I wanted to clear up.
    Thank you for your patience, many don't bother with a second try.

    No worries.

    If the key is for the Pro pack w/WMC, then it cannot be used to activate a Windows 8.1 Pro installation.

    Windows 8.1 Pro can only be activated with a product key that is specifically for Windows 8 Pro or Windows 8.1 Pro, and not with a key for WMC.

    Activate retail Windows 8.1 with Windows 8 Product key.

    I have a separate key for Win 8 pro and then a separate one for the WMC. Having 2 keys I remember and have them.
    I then went to the store and when I installed 8.1Pro the WMC was either there or asked me to enter the Win 8 key, I don't recall.
    I then made a dvd of 8.1 Pro.
    I have a different product key for Win 8.1.
    That is why I asked if I could use the new/different Win 8.1 prod key with the dvd.
    Maybe it is in vain b/c I would likely lose the WMC, or not?
    So I have the key for Win 8, a different one for the Win 8 WMC and a different key for Win 8.1 Pro.
    The same applies to the laptop.
    I hope this is not too confusing. Peter

    If you have a separate Windows 8.1 Pro key that is not for WMC, then sure you can use it to activate Windows 8.1 Pro.

    Product key or Product ID? If you are referring to the Product ID: as shown on the System screen that is not the same as the product code and can't be used to install or activate Windows with.

    When I right click this PC and select properties, it says Product ID followed by digits and on the right at the same level it says, Change product key. So two words are used on the same line.

    The Product ID listed there is not your product key.

    Product Keys and Product IDs are two completely different things,
    despite the similarity of the terms.

    The 20 character Product ID is created during the installation
    process and is used to obtain/qualify for technical support (ex: activate by phone) from Microsoft; it is of no use during the
    installation process.

    The 25 character Product Key is used to prove ownership of a
    legitimate license and is required to enter during installation to activate with.

    I don't know if this will help or not.
    If not, I'll delete it.
