Windows 10: Windows 10 product key not activating Windows 11 with error code 0x803fa067

I have been running Windows 10 Pro 64 for years. I have installed Windows 11 fresh on a different drive in the same PC. I have tried activating Windows 11 with the Windows 10 Product Key but I get error code 0x803fa067

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

I can't activate Windows 10, error code 0x803FA067

Hi there!
I was trying to activate Windows 10 on my computer when I got the error code.
Windows suggested to do a troubleshoot, but whenever I press the button for that the options menu just "freezes" and I can't click anything.
Is there any other way to enter my product key?
