    How to Change the Product Key Number in Windows 8 and 8.1


    information   Information
    This tutorial will show you how to change the current product key number to a different key to be used to activate your Windows 8 and 8.1 with instead.

    For example, to use to activate "Windows 8 Enterprise" or "Windows 8.1 Enterprise".

    You must be signed in as an administrator to be able to do the steps in this tutorial.

    Note   Note
    You can only use a product key number for the same Windows 8 edition that you currently have installed. For example, you cannot enter or change the product key number in Windows 8 with a Windows 8 Pro product key number, or vice versa.

    Once Media Center is installed (whether turned on or off in Windows Features), only product key numbers for "Windows 8 Pro with Media Center" will work to activate Windows. Microsoft regards this as a different version of the OS to all intents and purposes. In other words only keys obtained for Windows 8 Media Center will work from then on should you wish to change the key.

    In addition to the note at the top of this page: It should also be noted here that once Media Center is installed (whether turned on or off in Windows Features), only keys for "Windows 8 Pro with Media Center" will work.

    You're welcome Shawn. Actually I had posted exactly the same as your tute elsewhere only to realise you had already posted it so erased the content...;-)

    I qualified my statement above a little more by the way.

    Hello RatusNatus,

    Sorry, but no. Peter, just meant that you would only need to use a WMC key to change the key with if WMC is already added.

    This tutorial is if you wanted to change the Windows 8 product for whatever reason, and to be able to activate Windows 8 Enterprise since it's not activated during installation.

    You would install Windows 8 with the Windows 8 product key first, then use "Add Features" to enter the WMC key to add it back.

    Windows Media Center - Add to Windows 8


    Hope this helps,
    Shawn

    Brink, I've seen this a lot about changing the product key. I am confused. Why would you want to change the product key? If you change it from the one that you got with the program . Its the wrong one and won't activate. Will it?

    Hello Clint,

    The product key you enter would indeed have to be for the same edition of Windows 8 that is currently installed.

    If Windows 8 activates normally during installation, then there's really no need to use this.

    This would mostly be helpful to activate Windows 8 Enterprise since it doesn't activate during installation like the other editions of Windows 8.
