The issue with Tinywall is it won't alert you when it's blocking apps. Since a lot of Windows apps are a conglomeration of EXEs just whitelisting the main app is often not enough. Comodo is WAY more bloated than Tinywall but I use it because I can set it to alert me to everything that tries to access the internet, and choose to block it or not.
