Windows 10: Changed motherboard and windows 10 is no longer activated

So I decided to get an upgrade on my pc so I got a new motherboard, CPU, and power supply. Now my windows 10 is not activated. I tried troubleshooting and tried to get it re-activated but Microsoft said I cant.

Activate Windows 10 after motherboard change

Hi,

Thanks for the reply.

I built the PC myself and it is\was a retail Windows 8 Pro license upgraded to 10.

The guide listed that I should be able to transfer the license, and following the steps given when selecting "I recently changed hardware" in the activation process it does not list my previous device to select from.

My Microsoft account is logged in on both my old and new motherboard, and my old motherboard is unable to boot at all to deactivate or retrieve any keys.

If my license is indeed available for transfer, how can I proceed from here?

Thanks.

 

Windows 10 License (after motherboard change)

Hi Harsh,

Please be informed that your copy of Windows 10 should get activated automatically after changing the motherboard (once you enter the linked Microsoft Account details). But if you face any issues,
I suggest you to go through Phone activation to activate your Windows 10 copy.



To run Phone activation please follow the steps below:

• 
  Press Windows + R key.
  
• 
  Type slui 4 and hit enter.
  
• 
  Select the Country or
  Region.
  
• 
  Follow the on screen instructions.
  

Hope this helps. Please respond if you have any further related query.



Thank you.

 

Having trouble activating windows after changing motherboards

Hi, Peter,

When you changed the Motherboard was it through the OEM manufacturer?

Once you change and do not go through the OEM steps to switch motherboards, the pc is considered a New PC which does require purchasing a New License for Windows 10.

Try the Activation Troubleshooter

https://support.microsoft.com/en-us/help/20527/...

If you made a significant hardware change to your device (such as replacing the motherboard), Windows 10 might no longer be activated and you might see the activation error codes 0x803f7001 or 0xC004C008. If you're running Windows 10, version 1607 or later
and you added your Microsoft account to the new device, the digital license will be linked to your device. When you see these error codes, you can use the Activation troubleshooter to reactivate Windows.

If your Original Hardware Manufacturer (OEM) changed the motherboard for you, your PC should reactivate automatically or you should be provided with a replacement product key. If you see the Activation error Unable to reach Windows activation servers, and then
follow the steps in this additional help article.
