Yeah infact it’s the whole point of little snitch. You have to be aware of all traffic.

You know these threads are mostly astroturfed because nobody mentions Binisoft/Malwarebytes WFC, one of the oldest and better Windows application firewalls. It's also totally free, though not OSS.

WFC allows you to block Windows components. This can cause a lot of trouble, or keep Microsoft from spying on you. Or both.

Isn't WFC just an interface to the built-in Windows Firewall? It implements all its features by either changing built-in settings or monitoring built-in logs.

I definitely use it and recommend it though, it's great.
