Windows 10: I have a problem with windows 10 activation (0x803fa067)

I bought this new PC with windows 10 pro pre installed and activated. I start using it, and for the first week there wasn't any problem. Today I bought a wireless USB WiFi adapter and connected to my computer. So, when I finally start having internet I logging in my Microsoft account and start updating somethings that windows update ask for. when it finally end the installations, I restarted my PC. then appears a notification that told me to activate windows. and there is my problem I have been using a genuine and activated windows 10 for a week and now it says "we cant activate windows on this device because you dont have a valid digital licence or product key", and I have it, it was working for a week and now it doesn't. Please Help me...

Activation/Upgrade Error 0x803fa067

I tried to Updgrade my windows 10 Home to Windows 10 Pro.
I tried it with the default key that upgrades Windows 10 to pro without activating it(which is done in the second step).

The Universal-Key for Windows 10 Pro which is published by Microsoft is VK7JG-NPHTM-C97JM-9MPGT-3V66T. I tried that one but I get the error 0x803fa067.

I first tried it with the Windows 10 Settings using the Change Product Key Button in the Activation "Tab" And second with the command slmgr.vbs -ipk VK7JG-...
Both methods werent succesfull.

What the error originally means is: you don't have a digital licence or a valid Product Key.
I guess either the newly bought laptop was delivered with a fraudulent license( then microsoft is bluntly lying to me)





or the error message isn't quite correct. In this case I would go with my second guess

I am not sure why this Problem occures, so my question is: why do I get the Error 0x803fa067?
I am aware of the fact that I could reinstall Windows 10 Pro(which is the way I will probably do it) but I am intrigued to know how I could resolve the Problem without spending those extra 15 minutes.
