Windows 10: 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?

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:

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.
