Firewall events

In firewall events now it is blocked 21 things and all things are Windows operating system. What is this and how to stop this?

Anyone knows what and why it is blocked?

WOS is a pseudo process like System idle process in Windows Task Manager.

When no program is listening for incoming traffic it gets logged as being caught by WOS.

Im in the custom policy mode. When I tried to connect to vpn, firewall asked me about outgoing protocol 47 request of WOS. This is pseudo-procees which could do IP requests?
