    Moving Windows 8 Pro WMC upgrade to another PC


    Hi all,

    I had a laptop running Windows XP. When Windows 8 came out, I downloaded Windows 8 Pro upgrade (when it was something like 25 or whatever.) I clean-installed it and also upgraded to WMC edition when Microsoft were giving this away for free.

    Now that PC is kind of dying (it is about eight years old,) so I have bought myself a new one. The new one came running Windows 8 (not Pro, not WMC) OEM. I have no intention of ever using my old PC again, so my question is as follows:

    • How do I legally remove the Pro and WMC licences (and if required, Windows 8 itself) from the old PC and upgrade the new PC's Windows 8 to Pro WMC? I have a record of both the Pro and WMC product keys already. But how do I legally move them across to the new PC and upgrade the new PC's Windows 8 OEM to Pro WMC?


    Thanks in advance.

    Hello AK, and welcome to Eight Forums.

    You could do a clean install of your Windows 8 Pro to the new PC first, and activating it with your W8 Pro key.
    Afterwards, you'll be able to use "Add Features" to add WMC back with your WMC key like before.

    Hope this helps,
    Shawn

    Welcome to EightForums.

    To upgrade Windows 8 core, you need to use the Pro Pack.

    To upgrade to Pro Pack
    No install files needed.
    Only the Upgrade key is need.

    Windows 8 Pro WMC


    Hi guys and thanks for your responses and making me feel welcome.

    What I am particularly concerned about is will the new PC accept my product keys (i.e. first to upgrade Core to Pro, and then to add WMC) if Windows 8 Pro WMC is still installed on the old PC?

    If not, I can remove Windows 8 Pro WMC from the old computer by using my recovery discs to restore to factory settings (including going back to Windows XP).

    But crucially, if I do restore to factory settings, will Microsoft's activation system know that the Windows 8 Pro and WMC product keys are no longer in use on the old PC?

    If not, how do I let them know so that my Core to Pro upgrade and Pro to Pro WMC upgrade product keys work on the new PC?

    Thanks again for your help.

    As long as the PC doesn't come with Windows 8 preinstalled (OEM), then it's fully transferable to another PC using the clean install method I posted above without any activation issues. At worse you may have to activate by phone. The tutorial will cover activation as well.

    Thanks very much for your reply, and sorry to be a pain, but does that mean there is no process to just upgrade the new PC's Windows 8 Core to Pro and then to WMC without doing a clean install?

    Thanks again.

    Since you have Windows 8 Pro and not Windows 8 Pro Pack, it would need to be a clean install from Windows 8, then add WMC.

    The upgrade path to Windows 8 Pro doesn't support from Windows 8 (core).

    That's an interesting situation. My laptop came with 8 core preinstalled. I can't clean install 8 Pro with a regular Windows 8 ISO. My core key is auto detected and 8 core is installed by default. To get to 8 Pro I have to enter my 8 Pro key though add features. Then do it again to add Media Center. The Op having upgrade media instead of full install media seems to put a wrinkle in things. It will be interesting to see if it ignores the OEM embedded key. If it was me I think I would try entering the 8 Pro upgrade key in add features. If its rejected your no worse off and if it takes it you might save some hassle. I guess there's still the chance that it accepts the key and upgrades, but doesn't activate.

    When using a Upgrade key in add features, the key will not work.

    A full product key will work.

    I had a feeling that's what would happen, but I figured it couldn't hurt to try it. For future reference, now I know for sure it won't work.
