Windows 10: Re-activation of Windows 10 PRO licence after change of hardware - error code 0x803FABC2

I changed the hardware on my PC in order to be compatible with Windows 11. I have a Windows 10 PRO license. After the change of hardware motherboard, processor and memory, Windows requests re-activation. After following the procedure using the troubleshooting, I got the message mentioning the error code 0x803FABC2. However, I could not find any information about that error code and how to fix the problem.

Windows 10 will not activate Error code 0x803F7001

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem

 

Cannot activate Windows 10 Pro after hardware change (Digital Licence)

Hi,

I have attempted to install Windows 10 (clean install) following a hardware change (motherboard and CPU). Previous to attempting to get the new system, I had Windows 10 Pro, with my account linked to the Digital Licence. Everything I read prior to the upgrade
was indicative that I should be able to install Windows 10 to the new system without issue. However when I attempt to 'Activate' Windows 10 on the new system, I receive error code 0xC004C003. I attempted to run the troubleshooter, clicking on the 'I changed
hardware on this device recently' option, but get the 'Unable to activate Windows' answer.

I've attempted to reach a Microsoft consultant via tech support, but calling from Australia, I don't seem to be getting much luck in terms of being able too speak to someone to resolve it.

Any suggestions would be welcomed!

Thanks,

Art.
