    Windows 8 Pro license transfer a new Windows 8.1 computer?


    Hello Everyone,
    So I don't even know if this is possible or how I could go about doing this. Last year I bought a Windows 8 Pro upgrade disc we used to upgrade our machines from Windows 7 home Premium to 8 Pro. Is it possible for me to use that same upgrade product key for Windows 8 Pro on 8.1 so I could have a Pro version of 8.1? The computer I originally did the upgrade on I am no longer using and is there a way to deactivate the license on that one so it could be used on the new computer I bought? Also I just want the extra's of the Pro version so does it matter it is the license for Windows 8 even though the new computer uses 8.1? Thanks for any input.

You may also transfer the software (together with the license) to a computer owned by someone else if a) you are the first licensed user of the software and b) the new user agrees to the terms of this agreement. To make that transfer, you must transfer the original media, the certificate of authenticity, the product key and the proof of purchase directly to that other person, without retaining any copies of the software. You may use the backup copy we allow you to make or the media that the software came on to transfer the software. Anytime you transfer the software to a new

    So if I am not wanting to do a fresh install all I have to do is go under control panel> System and Security> System and then click on "change product key" and type in the product key from my Windows 8 Pro upgrade disc correct? That is what I am getting since I am not needing to do a fresh install, I am just checking so I don't do something and mess it up.

    How to transfer Windows 8/8.1 license to new computer.

    Note: This Windows 8.1 installation media accepts Windows 8/8.1 product keys, both OEM and retail (for example, "Windows 8 Pro $15/$40 Upgrade Offer" product key).

    1. Create installation media for Windows 8.1

    - The Windows Installation Media Creation Tool works on Windows 7/8/8.1/10.
    - The download succeeds without product key.
    - Both the 64-bit installation media (USB flash drive and DVD) can be booted in both UEFI and Legacy BIOS boot mode. Both the 64-bit installation media are also compatible with Secure Boot.

    Select either USB flash drive or ISO file (see screenshot below).

    Note: You need at least 8 GB USB flash drive (if you select option "USB flash drive").

    If you previously selected the ISO file option and once the ISO file is created, select the Open DVD burner option (see screenshot below).

    2. Uninstall current installed product key.

    Before you install Windows 8.1 to a new computer, you will need to uninstall current installed product key from your old computer.

    > OPTION ONE <

    Delete the old Windows installation, for example:

    - Boot the computer using the Windows 7/8/8.1 installation media.
    - On the first screen, press SHIFT+F10 to bring up the command prompt.
    - Run the following commands at the command prompt.

    diskpart
    list disk (this will give you a listing of the disks on your system)
    select disk # (select the disk you want to clean, for example select disk 0)
    clean (running the clean command will delete all partitions on the disk)
    exit

    > OPTION TWO <

    Uninstall product key from your computer's registry (see screenshot below).

    Open the command prompt as administrator and type (or copy and paste) the following command.

    slmgr /upk

    Click image for larger version

    3. Clean install Windows 8.1 from USB/DVD.

    Enter your Windows 8/8.1 product key (see screenshot below).

    Note: If the Windows 8.1 installer does not accept your Windows 8/8.1 product key, it means that you have the wrong installation media.

    Click image for larger version

    4. When Windows 8.1 is installed, check to see if Windows is activated.

    If your Windows is activated successfully, you will not see Activate Windows in the PC Settings.

    Click image for larger version

    The activation page shows the following message (see screenshot below):

    This product key is being used on another PC. Please try a different key.

    Note: Click on the Call support option (see screenshot below).

    Note: The activation robot asks you how many PC's you have installed Windows on. The correct answer is number 1.

    - Installing using UEFI boot mode or Legacy BIOS boot mode. -> link
    - How to download and clean install Windows 8.1 if you have an OEM computer with UEFI firmware (BIOS) embedded Windows 8/8.1 product key. -> link

    The activation page does not show the "Call support" option.

    This happens when you install Windows 8.1 using the Windows 8.1 generic product key.

    Click on the Enter key option (see screenshot below) and enter your Windows 8/8.1 product key.

    Click image for larger version

    You will see the following error message (see screenshot below): This key didn't work, please check it and try again, or try a different key.

    Click on the Cancel and now you will see the Call support option.

    Well I just got off the phone with Microsoft, so basically I will have to do a clean install of my Windows 8 Pro and then upgrade to 8.1, complete crap. They said they would not give me a new product key for my disc, that I will have to downgrade and then upgrade.
