After opening the Firewall settings page, you will find a link with the name ” Allow an app or feature through Windows Firewall” or ” Allow a program through Windows Firewall ” at the left side panel. Click on that link and you will be redirected to the next page.



There you will find an application list and check boxes next to each of them with a network distinction of “Home/Work (Private)” or “Public” network. To be able to change the settings, you have to click on the “Change settings” button on the upper right side of the window. You may be asked for a password, if so, give it right there.


Now, you are allowed to block any certain program from internet access. Just click on any program and uncheck all the checkboxes in that row to block it completely.
