Windows 10: Windows suddenly not activated anymore after Update

So, as the title says, this morning i got some windows updates "KB4579311". I don't know if the update is the reason, but suddenly my windows says that it isn't activated anymore.

I installed this PC cleanly 1 week ago and everything was fine until now.

I used some commands and programs that got recommended in the net, maybe it will help:

So, what can i do? write to the microsoft support? Write to the seller/amazon?

Edit: Some further infos. Windows says "the last input product key can't be used for this version of windows" (in german). It gives the 0x803FA067 and 0xC004C003 errors.

Windows Update suddenly hangs?

Windows Update is suddenly hanging for some reason... I went and downloaded and installed the first bunch of updates, restarted when asked, and now when I go back to windows update I just get the window with a white box forever. Reboot and it still does it. This happens to be on my main machine, running windows 7.

I've also noticed when I reboot it says configuring windows update, step 3 of 3, 47%. Maybe it somehow skipped something and is screwed forever?

 

Windows updates...

You cant just disable it anymore.
