How to Set Up Windows Firewall

Protect your computer with Windows Firewall.

A firewall can help to protect your computer from malicious software and intruders by monitoring all incoming data and connections. The firewall blocks any unauthorized attempt to connect to your computer from the Internet or your local network. Although you can purchase a firewall program to protect your computer, you can save money by enabling the Windows built-in firewall utility called Windows Firewall. You can access the Windows Firewall utility through the Control Panel.

Instructions

1. Click "Start" and then select "Control Panel."

2. Type "Firewall" into the search bar at the upper-right corner of the window and press "Enter."

3. Click "Windows Firewall" in the results list.

4. Click "Turn Windows Firewall On or Off" in the left pane of the window.

5. Click the "Turn on Windows Firewall" check box in each network location.

6. Click the "Block all Incoming Connections, Including Those in the List of Allowed Programs" check box to block all incoming connections. Click the "Notify me when Windows Firewall Blocks a New Program" check box if you want to be notified of all attempts to connect to your system. Click "OK" to save the settings.
