TinyWall – A free, lightweight and non-intrusive firewall

tl;dr: a free firewall for Windows which blocks everything by default and doesn't alert you when a program fails to go through it - instead, blocked things go into a "recently blocked" list going back up to 2 minutes, where you can explicitly whitelist them.

Windows Firewall has pretty bad defaults (e.g. unrestricted outgoing traffic among other things) and its advanced mode is a pain to work with. I've been using TinyWall for a while and it's come to be one of the first things I install on a fresh system.

Disclosure: I am not in any way involved with this software nor its author.

it works very well with screen readers. Lots of firewalls and malware programs don't witch screws over blind people who want to stay safe on there computers. I use it on windows 10 with NVDA.
