No Windows Key found

Hey there, i have a problem with my GemiBook. I started the Laptop and it says i need to activate Windows but when i try to do that it says that there is no product key available. I already tried the solution from another thread with that command:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

But that did nothing. I just get a blank response in the cmd window.

Can you help me?
