The firewall solution that Windows provides (Windows Defender Firewall) is excellent when it comes to blocking access to the Internet in a more general fashion. It does allow you to “whitelist” specific apps and programs, but that forces you to perform a number of steps each time you wish to whitelist or blacklist an application. Well, that is what OneClickFirewall does for you with just one click.
This tiny and free utility merely opens two new options on your Windows context menu – Block Internet Access and Restore Internet Access. That is all you need to grant or revoke access to one specific program while keeping your general firewall settings as they are. The only drawback is that you need to locate the executable file that opens that specific app in order to block or restore Internet access for that program only. And that isn’t always that straightforward, especially when they are buried below a series of cryptic folders and subfolders.
Other than that, OneClickFirewall is as simple as it can get. And it works, which is the best thing about this tiny tool. Say, for a moment, that you wish to block access to the Web to one of your browsers, or you wish to make sure that certain apps do not contact their official websites to install updates that you haven’t requested – well, this is where this free tool comes in really handy. It allows you to block a program from accessing the Web for as long as you need, and without changing your default firewall settings and preferences. more
