Windows 10: Error with Windows 11 Activation

The computer I'm working with is having some unknown problem activating. There have been a few fixes I've tried like removing the key via Command Prompt and reassigning it, using a dummy key for activation offline and online, resetting and updating between these tests, and of course running the generic troubleshooter, but none of these have brought about any positive results.The error is:We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license key, select Troubleshoot below. Error code: 0xC004C003Windows 11

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

Hi Greg,

This error code is usually caused by a problem with the product key. For better assistance, we would like to clarify how you got the Windows 10 Pro? Is it supplied by a company?
