Windows Defender Firewall

Go to the search tab and type firewall. Select windows defender firewall.  Click on advanced settings.  Block all incoming and outgoing traffic by default. Then wipe out all of the policies or click disable, better to click delete and remove them.  Then add the policies that you need.  Lock them down by application if need be. Play around with the detailed rules and use filters for programs, ports and ip addresses to get the desired effects for your network applications to work. Adding new programs magically changes your firewall settings, but go back and fix them after each new application install. Wipe out and delete all inbound rules.  If you need to let inbound come in, then you should know enough about the application to configure it. 
Block everything and only let out/in what you need to go out/in, specific programs, ports and ip addresses.
