Windows 10: "Unable to activate Windows" error

I am having a problem when activating Windows on this Toshiba Satellite L550. I typed in the product key and I clicked "Activate". It just took some time and it went into an error. It says "Unable to activate Windows, We can't activate Windows on this device because you don't have a valid digital licence or product key. If you think you do have a valid licence or key, select Troubleshoot below. 0x803fa067."How to activate Windows again on this computer?

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:
