Firewall is a tricky thing in Windows. It restricts your downloads at times, stops you from remotely connecting to a PC and blocks applications from running, which is quite irritating. But so far this is a top-notch security feature provided by Windows if you know how to use it right. You can configure your firewall to block particular applications from using the Internet and securing your local data.
Block applications from accessing the Internet with GUI is easy. simply go to the Start menu and search for Firewall & Network protection. From the dialogue box, click on Domain Network and turn the Firewall Off. Likewise, you have to turn off the firewall for Private Network and Public Network. In case you need to turn off the firewall only for the Internet, turn off the Firewall only for Public Network.
Disable Windows Firewall With Command Line
However, if you are like me who prefer to disable Windows firewall with the command line, here’s a quick way to do it on Windows 10 and 7.

Block Any App in the firewall (Command Line)
To block any app in the firewall, we first need to understand what is the inbound and the outbound rule. Inbound rules are defined to either block/allow the app from receiving data on your computer. Outbound rules are defined to either block/allow the application to send data from your computer.
To block any in Firewall using GUI is easy. All you have to do is go to the Firewall & Network Protection.
Click Advanced Settings and go to the Outbound rules tab. Click on New Rule on the right-hand side of the window. Select Rule Type as Program from the pop-up. Click on Next and further steps like specifying program path are self-explanatory.
However, doing the same with the command prompt is not that intuitive. First, you need to decide whether you need to block the app from receiving or sending data from the Internet. Say, you want to block Chrome app from accessing the Internet.
Next, we need to find the location of the .exe file in our system. Usually, it should be in C:Program Files, unless you have defined it manually.
Go to the .exe file and copy the path name. In my case for google chrome, the path would be :
Once you have the file location, all you have to do is open Command Prompt with administrator privilege and type the following command :
Now when I open chrome, internet access is disabled.
