How to use Windows Firewall

Using a firewall in Windows on your computer does not have to be tricky or difficult. It can be the adequate, non-invasive protection you need from would-be intruders. These brief steps will guide you through the process.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Microsoft Windows
• Computer
• Built-in firewall for Windows

1. 
   Control Panel selection

   Go to the "Control Panel" on the Windows Start menu.

2. 
   Windows Firewall choice

   Once in control panel, click on "Windows Firewall." The selections are in alphabetical order. If you accidentally click something, just hit the "Esc" key to exit or click the red "X" on the top of your screen to exit.

3. 
   Windows Firewall Security Screen

   When inside the Windows firewall screen, make sure the green "On" radio button is selected. If not, go ahead and turn it on. You will be able to see it right away and could be getting security alerts on your taskbar in the lower right-hand corner.

4. Click "OK" and click the red "X" in the upper right hand corner to exit out of this screen. You should now be protected.

5. There are two other tabs in the security screen for exceptions to software and ports, you generally do not need these as software can often configure itself to run with a firewall.

Tips & Warnings

• Do not run two firewalls, as they may conflict with each other. If your security software provides a firewall, you may wish to turn windows firewall off or the software can do this for you.
