With Windows Firewall Troubleshooter

If the Defender firewall blocks applications for no apparent reason, the first thing you have to do is go directly to the Windows Firewall Troubleshooterwhich not by chance bears such a name.

  • Press Win + I to open Settings, and open the System tab on the left panel
  • Scroll down, and click on Troubleshooter
  • Go to Other Troubleshooters
  • At the bottom of the page, click the Run button for Incoming Connection
  • The Troubleshooter will try to detect the problem and ask for your feedback.
  • Select between the options, and wait to see if the problem is detected

If a problem is detected, and Windows tries to solve it, the next thing to do is to try if the message no longer appears.

Scanning the system for malware-related issues

Now, if you don’t discover any problems with the previous tutorial and the security warnings are still seen every time you want to open an application repetitively, you have to check the system for malware.

Disabling the VPN client

It’s a fact that Microsoft Defender doesn’t play well with Virtual Private Networks, so if you have a client running, the obstacles to an overall good user experience may start to creep in.

To exit the VPN, you have to enter the program in question, go to the icon that is usually located in the upper right and select Exit. Once that conflicting app is launched, reopen the VPN.

Allowing access to applications

As we have already mentioned, although it is not ideal, you can Allow access one by one to the executed applications. When you do, firewall will understand that they are not risky, and the next time it will run them without asking you anything. It might eventually, but that would only point to an extra problem with the system.

Restoring Windows Defender settings to default

If the Defender firewall is still blocking some apps you want to run, there is no choice but to return it to its default values, which will make it work as stable as it used to until a few days ago.

  • Press Win + X and click Run
  • Type control and click OK, to open the Control Panel
  • Go to the System and security section and, once inside it, go to Windows Defender Firewall
  • Click the Restore Defaults button and confirm the action to take
  • Windows Defender will inform you when it has been reset

Needless to say that Restoring the program’s default settings will lose any customizations you may have made.although this is a lesser evil compared to the previous problem.
