In Windows 10, the old Windows Firewall has been rebranded by Microsoft to Windows Defender Firewall. It is a security feature built into the operating system that helps block unauthorized access to your computer, while permitting authorized communications. This tool can filter both inbound and outbound traffic or set rules and exceptions, depending on the type of network to which you’re connected. In this article, we’re going to show you how to allow apps through Windows Defender Firewall, as well as how to block them from going online. You’re going to learn to edit existing connection rules, add new apps to the list of exceptions, and remove them from it. Let’s get started:

Where to find the list of allowed apps (Windows Firewall)

First, open Windows Defender Firewall and, in the main window, click or tap «Allow an app or feature through Windows Defender Firewall.»

Картинка с сайта: www.digitalcitizen.life

You can now see a list of all the apps that are allowed to communicate through the Windows Firewall. The list is pretty long, and the active rules are only those with a checkmark near their name. All the rules can be enabled either for one type of network location (private or public) or both.

To change the list of active communication rules, you need to first click or tap the «Change settings» button.

Now you can enable or disable any of the already present Windows Firewall rules by placing a checkmark in the checkboxes found on their right sides. You can also change the type of network location the rule applies to by checking the appropriate column: private, public, or both.

Next, let’s see how to allow apps to communicate through Windows Firewall, and then how to block a program in the firewall from Windows 10:

How to allow apps to communicate through Windows Defender Firewall

The easiest way to allow an app through Windows Firewall is to do so when running it for the first time. When that happens, Windows Defender Firewall asks whether you want to let it go online or not. Check the network types on which you want to allow the program to access the internet, and then press Allow access.

An alternative method to allow apps through Windows Firewall is to look for them in the list of «Allowed apps and features» to which you can get as we’ve shown you in the first section of this guide. When you find them, mark the Private and/or Public options on the right, depending on which types of networks you want to allow that app to communicate.

If you want to know more about a rule before allowing a particular app through Windows Defender Firewall, first select it and then click or tap on Details.

Картинка с сайта: www.digitalcitizen.life

Then, you see a small window, giving you an additional description of the selected app. When you’re done reading it, click or tap OK.

If you cannot find an app in the list of allowed items, you can click or tap the «Allow another app» button to add it.

In the «Add an app» window, you can see the list of all apps installed on your computer. Select the one you desire. If you cannot find it, press Browse and select its main executable file.

You can set up which location type the exception is applied to. To do this, click or tap «Network types.»

Then, you can check any of the location types: private or public. When done, press OK.

Next, press Add.

The app is now added to the list of allowed connections and should start functioning correctly.

How to block a program in Windows Defender Firewall

To block a program in the firewall from Windows 10, there are two easy paths that you can follow. The best and the one that we recommend is to manually create a firewall block rule by following the steps in this tutorial: Block apps and games from accessing the internet with Windows Defender Firewall.

The second path is somewhat unorthodox, but it works. 🙂 By default, Windows Defender Firewall is set to «block all connections to apps that are not on the list of allowed apps.» This means that if you remove an app from the list, its internet access is automatically blocked.

Follow exactly the same steps as in the first section of this guide to get to the list of allowed apps. Then, when you get to it, locate the app that you want to block in the firewall, select it, and remove it from the list. You can do that by pressing the Remove button.

When you’re asked to confirm, click or tap on Yes and the app is deleted from the Windows Defender Firewall rules list.

This doesn’t automatically block that app from communicating over the internet. However, the next time you open it, and it tries to go online, Windows Defender Firewall should ask you whether to allow it or not. Choose not to let it go online so that the app is blocked.

Are you comfortable using Windows Defender Firewall?

Working with Windows Firewall is not that complicated, even if you may feel intimidated by it. As you can see, adding or removing apps from the list of allowed connections is reasonably easy. If you have questions about this topic, don’t hesitate to leave a comment. Also, to find out more about this tool, check out the articles recommended below.

You will encounter the Windows Defender Firewall has blocked some features of this app security alert when you try to launch a program on a Windows computer. While you can click Allow access and proceed to launch the program, the pop-up can get annoying if it appears frequently.

Fortunately, you can configure Windows Firewall to stop this message from appearing. Below we discuss why this message appears and how to deal with this security alert in the Windows operating system.

What Triggers the «Windows Defender Firewall has Blocked Some Features of this App» Alert?

Windows Defender Firewall keeps track of all the applications trying to connect to the Internet and accepts incoming connections on your PC. When it detects an app trying to connect to the Internet for the first time, it will block access and show the above message.

If you trust the application, you can click Allow access. If not, click Cancel, and the application will stay on the blocked list until you allow it the next time.

This is a preventative measure to block sneaky apps and threat actors from gaining access to your computer. On the flip side, this security measure can be infuriating if the Windows Defender Firewall starts blocking apps frequently.

If this message repeatedly appears with the apps you have previously allowed, it is better to take a few minutes and investigate the application for issues.

In the case of a web browser, you may have a dubious plugin trying to access the Internet, triggering a security alert. In other instances, VPN clients are known to trigger this security alert quite frequently.

Here are a few things you can try to stop the Windows Firewall security alert message on your PC.

1. Run the Windows Firewall Troubleshooter

Let’s start with troubleshooting the Windows Defender Firewall for the incoming connection issues. Windows 10 and 11 come with a built-in Incoming Connection troubleshooter. It lets you find and fix problems with incoming connections and Windows Firewall.

To run the Windows Firewall troubleshooter:

1. Press Win + I to open Settings.
2. Open the System tab in the left pane.
3. Next, scroll down and click on Troubleshooter.

4. Click on Other troubleshooters.
5. Next, scroll down to the Other section.
6. Locate and click the Run the button for Incoming Connection.
   

   Картинка с сайта: www.makeuseof.com

7. The troubleshooter will try to detect the problem and require some input from you.
8. Select one of the options and click Next. The troubleshooter will now look for problems in the selected area and apply a fix if required.
9. Once done, click Close and look for any improvements.

2. Scan Your System for a Malware Issue

If the security alert repeatedly appears randomly for a specific app or all the apps, it is better to check your system for malware issues. If you have a third-party antivirus, perform a complete scan to find any malware infection.

To perform a Scan using Windows Security:

1. Press Win + I to open Settings.
2. Open the Privacy & security tab from the left pane.
3. Click on Windows Security.
   

   Картинка с сайта: www.makeuseof.com

4. Click on Virus and Threat protection under the Protection areas section.
   

   Картинка с сайта: www.makeuseof.com

5. In the new Windows Security window, click on Scan options under Quick Scan.
6. Under Scan Options, select Full Scan.
   

   Картинка с сайта: www.makeuseof.com

7. Next, click the Scan now button to initiate the scan. This will check all files and running programs on your hard disk.

A full scan often takes a long time to complete depending on the data stored on your hard disk.

3. Disable Your VPN Client

Картинка с сайта: www.makeuseof.com

Windows Defender Firewall can block incoming and outgoing connections from a VPN client. If you have a VPN client running, close it and exit the app completely.

To exit the VPN app, click the up-arrow icon in the system tray (bottom right corner of your desktop), right-click on the VPN app icon, and select Exit.

If the issue persists, try to disable the VPN network adapter in the Device Manager. Here’s how to do it.

1. Press Win + R to open the Run dialog.
2. Type devmgmt.msc and click OK to open Device Manager.
3. In Device Manager, expand the Network adapters section.
4. You can identify the VPN network adapter by the VPN client name. For example, if you use Hotspot Shield VPN, the adapter will have a similar name.
5. Right-click on the VPN network adapter and select Disable device.
6. Click Yes to confirm the action.

Once disabled, check if the issue is resolved. If not, look for other VPN network adapters and disable them via the Device Manager.

4. Allow the App Through Windows Defender Firewall

You can click on Allow access to add the blocked application to the allowed list in Windows Defender Firewall. However, if the app continues to ask for permission, you can manually allow the app through the Defender Firewall.

To add the program to the Windows Firewall whitelist:

1. Press Win + R to open Run.
2. Type control and click OK to open the Control Panel.
3. In Control Panel, click on System and Security.
   

   Картинка с сайта: www.makeuseof.com

4. Next, click on Windows Defender Firewall.
   

   Картинка с сайта: www.makeuseof.com

5. In the left pane, click on Allow an app or feature through Windows Defender Firewall.
   

   Картинка с сайта: www.makeuseof.com

6. Click on Change settings to enable the option.
7. Next, scroll through the list of apps and features and locate the program you want to allow through the firewall.
   

   Картинка с сайта: www.makeuseof.com

8. Check both the Private and Public boxes to add the app to the Windows Defender Firewall whitelist.
9. Click OK to save the changes and exit the Control Panel.

If the program you want to allow is not on the list, click on Allow another app, browse the app’s installation directory, and select the executable. Then, click Add and save the changes.

5. Restore Windows Defender Firewall Settings to Default

An incorrectly configured Firewall can act erratic and block genuine apps. If you have recently made any changes to the Firewall but are unsure of the exact details, you can restore the default settings.

Restoring the default will remove all the third-party modifications and reset the Firewall to factory default.

To restore default for Windows Defender Firewall:

1. Press Win + X and click on Run.
2. Type control and click OK to open the Control Panel.
   

   Картинка с сайта: www.makeuseof.com

3. Next, go to System and Security > Windows Defender Firewall.
4. In the left pane, click on Restore defaults.
   

   Картинка с сайта: www.makeuseof.com

5. Click the Restore defaults button.
6. Read the description and click Yes to confirm the action.

Note that restoring default will reset all the changes you have made to your Windows Defender Firewall since Windows was installed. As a result, you’ll need to reconfigure the firewall if necessary.

Fixing the Intrusive Windows Defender Firewall Security Alert

The Windows Defender Firewall security alert is a common sight when using a Windows computer. It is a harmless alert that often occurs only once for any program. If you trust the app, click Allow access, and the message will never appear for the same app.

In case of a repeated occurrence, troubleshoot your system for potential issues, including malware infection and VPN conflict. If the issue persists and you trust the service/program to be genuine, consider turning off Windows Defender temporarily.
