How to block internet to an application.
Most of the time we want our applications online and connected to both our local network and the greater Internet. There are instances, however, when we want to prevent an application from connecting to the Internet.  I will show you how to lock down an application via the Windows Firewall.
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.
