How to Block or Allow a Program in Windows 7 Firewall

windows firewallWe have talked about many Windows applications which require network access to work smoothly. Whenever we talked about them, we mentioned a note that you must allow the program through a Firewall if at all you have one installed on your system.

I personally feel that Windows’ inbuilt firewall provides enough security to a regular home user and is extremely easy to use. If you are one of such users, today we will see how you can block and allow individual programs through Windows Firewall.

Sometimes, by accident or due to some other factors, a program may get blocked or allowed by the inbuilt firewall. Therefore, at times, one may need to change these settings manually. So let’s see how this stuff’s done.

Changing Firewall Program Access

Step 1: Conventionally, to open the Firewall settings in Windows 7 you need to open Control Panel from the Start Menu and then under System and Security click on Windows Firewall.

Still, why drag a horse to pond when the pond can come to you! Simply search for Firewall in Start Menu and open Windows Firewall from the list of returned items.

Step 3: Having done that, on the Allowed Program window, you will see a list of all the applications installed on your computer that can communicate through your network and their current access status on Home and Public network. The checkmark denotes that the program can access the internet through Windows Firewall.
