    I brought a laptop 2nd hand and it had Windows 8.1 before the person updated it to 10. Regardless of if I will actually need the key in future I'm used to having the product key of computers I own.

    windows 10 key

    Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

    You need to upgrade the first time around. Once you upgrade, you can use that key for a clean installation. I've done 2 clean installations with my Windows 7 key since I upgraded to 10 the first time around.

    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.

    Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.
