The Windows Firewall is a built-in security application that comes with Windows OS since the beginning. The software is built to filter network data transmission to and from your Windows system.

The Firewall will block any suspicious and harmful connection depending on the threat level.

While you may want most programs on your laptop to be connected, there are occasions when you’ll need to know how to stop Windows 10 apps from connecting to the internet — for example, if you want to prevent automatic updates of a particular app, or block ads on an app that works perfectly fine offline. Whatever your intention, here’s the best way to block programs from connecting to the internet in Windows 10.

The users can configure the Windows Firewall settings as per their need to block or open port in Windows 10 and other versions. However, at times the Firewall may block ports or programs accidentally by user’s or administrator’s misconfiguration.

Now, if you want to know if the Windows Firewall is blocking a port or program on your system, here is how to do it.

Why Do I Want To Do This?
Some of you might have been sold immediately by the headline, as blocking an application is exactly what you’ve been wanting to do. Others may have opened this tutorial curious as to why one would block an application in the first place.

Although you generally want your applications to have free access to the network (after all what good is a web browser that can’t reach the web) there are a variety of situations in which you may wish to prevent an application from accessing the network.

Some simple and commonplace examples are as follows. You might have an application that insists on automatically updating itself, but find that those updates break some functionality and you want to stop them. You might have a video game that you’re comfortable with your child playing, but you’re not so comfortable with the online (and unsupervised) multiplayer elements. You might be using an application with really obnoxious ads that can be silenced by cutting off the application’s Internet access.

Regardless of why you want to drop the cone of network connectivity silence over a given application, a trip into the guts of the Windows Firewall is an easy way to do so. Let’s take a look at how to block an application from accessing the local network and Internet now.
