What Is Windows Firewall?

Windows Firewall is a network security system that helps protect your computer from unwanted access and intrusion. It does this by blocking incoming and outgoing traffic that doesn’t meet certain security criteria. Windows Firewall is automatically enabled on all Windows PCs, but it’s important to configure it properly to get the most out of its features.

How to Enable and Configure Windows Firewall

Now that you understand the basics of Windows firewall, it’s time to learn how to enable and configure it on your PC.

To enable Windows firewall, open up your Control Panel and navigate to System and Security > Windows Defender Firewall.


Select the “Turn Windows Defender Firewall on or off” link on the left-hand side of the window.


You’ll see two different profiles: Public, Private. For most people, the default setting—Public—will be fine. If you’re using a home network, choose Private.


Next, click on the “Advanced settings” tab and make sure that “Windows Defender Firewall” is turned on. You can also choose to enable specific features here, such as authenticating communications between computers.


You can also choose to allow certain programs and ports through the firewall, or create custom rules for specific applications.

The Benefits of Enabling and Configuring Windows Firewall

Windows Firewall is a pre-installed firewall program in Windows that helps protect your computer from malicious attacks and control the traffic that goes in and out of your computer. Enabling and configuring Windows Firewall can offer the following benefits:

  1. Protection against malicious attacks – Windows Firewall can block unauthorized access to your computer, which can help protect it from malware, ransomware and other types of cyberattacks.
  2. Control over traffic – Windows Firewall can help you manage the traffic that goes in and out of your computer, so you can more easily control what applications and websites can access the internet.
  3. Improved performance – Windows Firewall doesn’t use a lot of system resources, so enabling it won’t impact your computer’s performance.

What to Do if Windows Firewall Is Blocking a Program

If Windows Firewall has been enabled and is still blocking a program, it might be because the program is deemed a risk by Windows. However, if you trust the program, there’s an easy fix.

In the Windows Control Panel, search “Windows Defender Firewall” and select “Allow an App Through Windows Firewall”.


You’ll see here a list of all the programs that have been granted access through the firewall. You can manually add a new entry by clicking on “Change Settings” and then “Allow Another Program” or you can select an existing entry and click on “Edit” if you wish to make changes.


Once you have selected or added a program, you’ll be able to specify which type of networks it can access (Home/Work or Public). If in doubt, keep this set to Home/Work for maximum security. Finally, click on the checkbox for each type of network to confirm your changes.

How to Check if Your PC Is Protected by Windows Firewall

This can be done by launching the Windows Security Center, which you can find in your Control Panel. Click on “Windows Defender Firewall” and then click “Advanced settings“.


If the Windows Firewall service is running and configured correctly, you will see a list of its current rulesets.


You will also want to check that all ports are correctly configured; this includes external ports, which should be blocked unless they are specifically allowed by the user. It’s important to ensure that all incoming and outgoing traffic related to applications and services are properly secured. You can also verify that all inbound traffic is being blocked unless it is explicitly allowed.


By following the simple steps in this guide, you can quickly and easily enable Windows firewall on your PC and help keep your computer safe from malicious attacks. Remember to configure your firewall settings as needed to ensure that your PC is as secure as possible. I hope you find this guide helpful, kindly leave a comment below if you have any questions.
