    Upgrade from Windows 10 Home to Pro using OEM Product Key


    We purchased a new computer which included an OEM Product Key for Windows 10 Pro.
    Rather than install Windows and then copy all the data and apps from our old computer which had Windows 10 Home, we cloned the old hard-drive to the new PC.
    This means the new computer is running Windows 10 Home, and we are now trying to use the new product key to upgrade to Windows 10 Pro.
    Not sure if it makes a difference, but the old computer was originally purchased from the same OEM as the new PC.
    The upgrade fails: "The the product key you entered didn't work. Check the product key and try again, or enter a different one. 0xC004F050"
    Are we doing something wrong, or is it not possible to use the OEM Product Key that came with the computer to upgrade from Home to Pro in this way?

    :)

  2. Upgrade a Win 10 home OEM to Win 10 Pro OEM with Win 10 Pro OEM Key?

    I recently purchased a laptop that has an OEM version of Win 10 Home on it.

    I verified this by using : slmgr -dli.

    Previously I had purchased an OEM Win 10 Pro Key.

    Can I use this OEM Win 10 Pro Key to upgrade the OEM Win 10 Home to the OEM Win 10 Pro.

    If so what are the steps to accomplish this?

    In addition, I assume that is this is possible, that the current product key will be updated to the new product key?

    The reason I am asking this is that it's my understanding that these product keys are tied to the bios on a name brand laptop.

    TIA

    Win10 Home to W10 Pro Upgrade Error using Product Key

    The keys are there because 1. It is the product key you end up with when you gain a digital license for Windows 10 Pro through legitimate means and 2. When you do a clean install of Windows 10 (without adding an ei.cfg file), on a computer with a product key for Windows 10 Home stored in UEFI, you can use the generic product key to upgrade the Windows 10 Home that installs by default to Windows 10 Pro - but only if you have an existing digital license for that computer for Windows 10 Pro previously stored on Microsoft Activation Servers.

    The reason the generic Windows10 Pro product key will not upgrade your Windows 10 Home to Pro is because you do not have a preexisting digital license for Pro for that computer stored on Microsoft activation servers.

    Can't upgrade to an OEM version of Windows 10 Pro with product key

    Hi.
    Have you tried this?
    Upgrade Windows 10 Home to Windows 10 Pro - Windows 10 Forums

    It may work .

    I'm thinking you'd be able to activate your W10 Pro install with your W10 Pro key after the upgrade.
