Firewall for most simple and essential task

[amazinghorse]

One of the most common example : you need to block some apps or "bad people" quick and easy.
So here we go
No useless features!
No over 100mb fat installers!
No slow and glitchy drivers!
All programs listed here for one simple purpose - block unwanted connections.
 
PeerBlock
 
PeerBlock lets you control who your computer "talks to" on the Internet.  By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries!  They can't get in to your computer, and your computer won't try to send them anything either.
And best of all, it's free!
Got very useful P2P black-list with regular updates (You will be wondered how many 3rd-party companies including isp's monitor your p2p traffic)! Must have!

TinyWall

TinyWall includes a combination of features that sets it apart from both commercial and freeware firewalls.
    TinyWall does not annoy you with popups at all, yet it is still extremely easy to add exceptions to your firewall rules.
    TinyWall does not require you to know about ports, protocols and application details.
    TinyWall prevents malicious programs from modifying the settings of Windows Firewall.
    TinyWall does not install drivers or other kernel components, is free and lightweight.
Very simple and lightweight.

Windows Firewall Control

Windows Firewall Control is a nifty little application which extends the functionality of the Windows Firewall and provides quick access to the most frequent options of Windows Firewall. It runs in the system tray and allows user to control the native firewall easily without having to waste time by navigating to the specific part of the firewall. This is the best tool to manage the native firewall from Windows 8.1, 8, 7, Vista and Server 2008.
Most flexible.

A word about Peerblock:

It does a good job about keeping unwanted connections blocked in a public swarm, but many private trackers do not like Peerblock because it may mess with some things apparently. You could use a IP blocklist in your torrent client to achieve the same effect, if need be.

#1 rule here - use right blocklists!

#2 sometimes monitor what is blocked

#3 frequent updates

About year of using, almost no problems
