Windows Firewall is a Microsoft Windows application that filters information coming to your system from the Internet and blocking potentially harmful programs. The software blocks most programs from communicating through the firewall. Users simply add a program to the list of allowed programs to allow it to communicate through the firewall. When using a public network, Windows Firewall can also secure the system by blocking all unsolicited attempts to connect to your computer.
