How to allow a program through firewall in Windows 10

If you are a Windows user, you might have come across the Windows Firewall, which acts as a filter to allow certain applications to access the internet depending upon whether you are connected to a private or public network. Windows Firewall is similar to the Internet Connection Firewall, that was available on versions prior to Windows XP and it was rebranded as Windows Firewall in Windows XP and the next versions of Windows. Presently, on Windows 10, it is again rebranded as Windows Defender Firewall but it acts almost the same way as that of Windows  Firewall on the previous versions of Windows.

What Windows firewall does is quite simple. It filters some applications on your computer from accessing the internet through private or public networks depending upon the behavior and other aspects of the program. If the developer of a certain program suspects, it will not be allowed to access the internet, due to the Windows firewall, you might get a notification at the time of installation of the program, which will ask whether the application should be added as an exception to Windows Firewall or not! However, if you trust a certain program and it is not allowed to access the internet or network, you can allow its access to the internet very easily. I will discuss, how to do that on Windows 10 in this tutorial here.

Steps to allow or block applications on Window 10 firewall

So without any further delay, let’s get started with how you can allow or block a certain program on Windows 10/8/7 PC or laptop through Windows defender firewall from accessing the internet connection on your computer.

Once you are done with everything simply click on ‘OK’.

Windows firewall is a quite reliable tool, which can automatically detect which programs can display suspicious behavior, and depending upon that, it will automatically allow or disallow the application from accessing the internet. Unless you are sure about an app, I will not recommend you allow it to access the internet as it might steal your data and send it to its own serves, which is not something that you will ever want.

But disabling certain app from accessing the internet can be very useful at times, as well.  If you have some program, which doesn’t require any access to the internet, for example, some offline programs to capture screenshots, or simple word processing programs, you can simply disable internet access for such applications. This will prevent the app from showing new update notifications so that you can work at ease. However, that is not recommended as from time to time numerous vulnerability are fixed through updates. But at the end of the day, the ability to allow certain apps and disable certain apps from accessing the internet can still be handy at times.

So that was the way, you can allow or block apps from accessing the internet using Windows Defender Firewall on Windows 10. Do you have any questions? Feel free to comment on the same below.
