Windows 10: Activation error after running Windows Update

Hey there,I've just updated Windows and after the reboot Windows tells me that "Windows reported that not product key was found on your device. Error code: 0xC004F213".I have changed a lot of my hardware last year new Mainbord, CPU etc but up until the update everything was OK and Windows was activated. I've also updated my Windows version from 10 to 11 last year, that was also flawless and no issues there. So something fishy must've happened during that update. When I click the "I changed hardware on this device recently" it shows me my old Laptop and 2 other Computer Names I don't recogniz

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
