Strange connections from ""Windows Operating System"

Hello everyone.

Take a look it the screenshot and see the listenings of the “Windows Operating System”. I haven’t seen such connections until updated to .530. RTHDCPL.exe is the audio driver, it should not try even to connect to the Internet.
Does someone has an idea why these listening?

It is only listening. That means it doesn’t connect to the web (yet). If it would connect you would get an alert.
