Windows 10: Unable to reactivate after motherboard and CPU change

I changed my motherboard, CPU and RAM. Because of this my hard disk had to be formatted and then when I tried to reactivate my Windows, I am getting the error code: 0x803FABBB. I had gotten Windows 8 years back and I have forgotten the product key. How do I activate my Windows?

Digital license won't reactivate on new hardware (motherboard, cpu ram)

Hello,

I have a digital license of Windows 10 that is linked to my Windows account. I've just replaced my motherboard, cpu and ram and whenever I attempt to reactivate my license the activation troubleshoot says "Unable to activate Windows, We can't reactivate Windows
on this device, Try again later.

Prior to changing my hardware I double checked my digital license, The activation said "Windows is activated with a digital license linked to your Microsoft account"

If I run 'winver' It also lists the produced is licensed to my Microsoft account.

According to this article below, All I should have to do is goto the activation troubleshooter and everything should work.

What are my next steps?

Thanks.

 

Windows 10 reactivate after motherboard and CPU change

I changed the motherboard and CPU on my computer and the digital license reactivation isn't working. I follow all the steps, (settings - update & security - Activation - Troubleshoot - I changed hardware on this device recently) the computer I am trying
to activate windows 10 on does not show up as one that I can choose. BUT when I go into my Microsoft account it is there under devices. Why is it not showing up as one I can choose to activate windows 10 on????

 

Unable to reactivate Windows after changing Motherboard

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that after changing the Motherboard you are unable to activate Windows. I’ll help you with the issue.



However, please let us know:

• What is the error message you receive when you try to activate Windows?
  
• Did Windows 10 come preinstalled on your computer?
  
• Were you using a Microsoft account to login to the computer?
  

Ideally, if Windows 10 comes preinstalled on the computer, the Product key is embedded in the Motherboard. In case Windows is reinstalled on the computer, it should get activated automatically. However, if any hardware changes (such as Motherboard
or hard drive) is done on the computer, Windows will not be able to identify the license.
