    Hi. I just bought a brand new pc with Windows 11 home, it wasn't pre-installed so i had to download the bootable USB version but every time I try to enter the product key it says the key is not valid. How is this possible, it was just bought.

  2. Convert a Windows 8pro product key to a Windows 10pro produkt key

    Hi Andre,

    Thank you for contacting Microsoft community.

    I suggest you to Uninstall the license using the following steps.

    • Press Windows key + X
    • Click Command Prompt (Admin)
    • At the command prompt, type: slmgr.vbs -upk
    • Press Enter, this will uninstall the product key from the computer.
    Further on, install Windows 8.1 activate the copy with the product key on the new machine. Then again upgrade the same to Windows 10 using Window Update or Media Creation Tool.

    Windows product key does not work

    windows live product key

    Hi,



    Thank you for your response.


    • Did you download the ISO of the Game from the Steam?
    It is not Windows Live Key, it’s a game product key which is required to install the game.

    I suggest you to check with Steam for Product key and check if it helps.
