I checked if windows updates was doing something but it was not. The latest update was already installed.
Then I tried a virus scan and Bitdefender suggested me to restart my PC for updates. Now the problem is fixed.
So for some reason Restarting my PC solved it. While shutting down last time I used it and starting it up again this morning did not fix the problem.
The windows updates sharing over lan was indeed enabled which I disabled. I found this and tried it before posting my problem here but it did not seem to do anything. Maybe restaring was needed to actually disable this feature.
Thanks for the help.
