How to Block/Unblock Programs using Windows Firewall in Windows 7

"Windows Firewall provides host-firewall protection on computers running. As a host firewall, Windows Firewall runs on each of your servers and clients, providing protection from network attacks that pass through your perimeter network or originate inside your organization, such as Trojan horse attacks, worms, or any other type of malicious program spread through unsolicited incoming traffic."

From previous post we already know about How to Block/Unblock Programs using Windows Firewall in Windows XP. Now, in this post I'll show how to do it in Windows 7.

1. Click the Windows orb and open the Control Panel.

2. Select System and Security.

3. In the Windows Firewall section, select Allow a program through Windows Firewall.

4. Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access.

If the program you wish to block or unblock is not listed, you can click the Allow another program... button to add it. Choose the application in the list and select Add. If the program is not in this list, use the Browse... button to select the program file manually.

Thats it. Hope this small tip can be useful for you.
