How to Unblock Something on Windows 7 Firewall

By Elvis Michael

The Windows 7 firewall prevents potentially malicious applications from infiltrating your system, allowing only the information you wish to send and receive. While the firewall automatically enables network access to a variety of programs, you can also manually allow any given software to relay information over the Internet. Such a feature is often a necessity in the workplace if the firewall cannot recognize a program on its own. Users may also choose to unblock a program or service that was previously blocked for troubleshooting or security concerns.

Click the "Windows" orb and click “Control Panel” in the menu that opens.

Click the “System and Security” section, followed by the “Windows Firewall” option on the following screen. Note that the Windows Firewall option is immediately accessible if viewing the Control Panel as Large Icons or Small Icons.

Click “Allow a Program through Windows Firewall” to access all monitored applications. Provide your account password or confirmation if you're prompted for this.

Tick the check box next to the program in question. Additionally, check whether to unblock it only within your home network and/or publicly if the program requires external Internet access.

Click “OK” to save your firewall settings and exit the application.


Removing the check box next to the application's name effectively prevents it from sending and receiving network communications.


Only allow access to applications you recognize and can trust to transfer data to and from your computer.
