    Changed MB and CPU; Can't reactivate


    I change my MB and CPU and now can't reactivate my Windows 10 Pro.

    The troubleshooter tells me:

    "It looks like the hardware on this device has changed. Make sure you're connected to the Internet and try again later. 0xc0ea000a"


    I AM connected to the internet obviously, since I'm posting here


    Using the "I changed the hardware" option doesn't list the device I upgraded. However, the desktop is still listed under devices in my Microsoft Account.


    In desperation, I even tried to buy a new license which I shouldn't have to do, but it would only let me upgrade to the Enterprise edition


    I entered the product key under change the product key and got the Unable To Activate error.


    It will not let me connect to MS customer support.


    I'm at wit's end.

    :)

    reactivating windows after changing the pc's CPU

    I am having difficulty in reactivating windows after changing the pc's CPU

    Prior to the change, I linked my digital licence to my MS Account

    In my MSA I can see both versions of my PC listed, once with the old CPU and once with the new CPU

    If I go to activation - troubleshoot- I changed hardware on this device recently, I can only select the old PC on which to activate windows

    Any help or ideas appreciated

    My computer is not present when reactivating Windows after changing the CPU

    Hi

    I changed my HW today (from an i5-4690k to a Ryzen 7 2700) but I cannot reactivate my Windows copy. My PC is not present on the list while reactivating and my Microsoft account is connected. Also, this is the first time I change the CPU. What should I do?

    windows10 reactivation after changing mb, cpu etc

    Hi John. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

    If Windows came pre-installed on the PC then changing the motherboard voids the license. Free Upgrade inherits that restriction. You'll need to buy a new license:

    If it was retail Windows then follow these steps for reactivating:
    https://support.microsoft.com/en-us/help/20530/...

    You can also ask for help from MS Support to get it activated:

    I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
