Windows Firewall is a vital system security and packet filtering component of Windows. This celestial feature enables users to create inbound and outbound data traffic rules to protect their PCs and network from malicious external sources, such as trojans, viruses, and hack attacks. The major function of Windows Firewall is to restrict third-party applications from sending and receiving data to unauthorized users/apps. Firewall generally automatically identifies trusted sources and adds an exceptions. Likewise, if a software seems fishy, it asks you about manually granting or blocking the permission. However, the Windows Firewall is not utilized up to its full potential by most users because it seems a bit tedious to configure and unleash its prowess. Most casual users cannot get the hang of its inbound and outbound rules. Back in 2008, we brought you a detailed guide on How to Create Exceptions in Windows 7/ Vista Firewall. Today, we have an application for Windows, which might provide an alternative and easier solution. It is called Firewall App Blocker, and allows you to add applications to the Windows Firewall block list via simple drag and drop operation. In addition, the application lets you set Windows Firewall policies by providing you with easy access to Windows Firewall with Advanced Security dialog box.
