The latest versions of the Windows operating system have a built in firewall that can be used to protect your computer from potentially malicious data and other attacks on your network. Whilst I would suggest that it is essential that you have a firewall, you may or may not need the Windows version to be active, depending upon whether you have any alternatives installed.
If you need to turn Windows firewall on or off, or are curious as to which state it is currently in, then read on.
Turning Windows firewall on or off
1. The first thing that you need to do is go into the Windows firewall control panel. This can be done in one of two ways.
Option one is to click on the Start button and then type firewall.cpl into the search box:
The other option is to press the Windows and R keys on your keyboard at the same time which will open the Run command:
2. After you have entered firewall.cpl in one of those two ways the firewall control panel will open. It looks exactly like the image below and you need to click on Turn Windows Firewall on or off.
3. This will open a new window, like the one you see below, and here you can turn the firewall on or off for either the public and/or private network.
4. Click on the OK button and your firewall will have been successfully switched on or off as you chose.
