In Windows, you can use Windows Firewall to block or unblock certain applications, but it doesn’t offer an easy-to-use interface for its advanced features. If you want to block an application from accessing the internet, you must go through the following steps:
1. Click the Windows Start Menu and open Control Panel
2. Select System & Security
3. Then in the Firewall section, you select “Allow a program through the Windows Firewall”
4. If the program you wish to block or unblock isn’t listed, you must click “Allow another program” to add it. Choose the application in the list and select “Add”. Else you must then browse the hard drive to find it, and so on. This seems complicated for the average user.
Firewall App Blocker makes the process very easy! Simply drag and drop the application you wish to block into the FAB window, or browse the hard disk to find it.That’s it!
What is new: (Wednesday, 28 September 2022)
[FIXED] – If you change GUI language, Enable WhiteList box disappears

In this version there are some extra features on the Firewall menu, including “White List Mode”, Block internet , Restrict Firewall Options etc.
What is WhiteList Mode: it will block everything except on the white listed items, to activate it tick the “Enable WhiteList” box on the right bottom corner , The whitelist mode denies access to all network interfaces, After enabling WhiteList Mode Drag and drop an Application/Applications on the “Firewall Application Blocker” interface to Allow it/them , It was the most wanted feature

Hello, I like the concept and simplicity of this program, but it does need “one” feature. That is a feature that watches for internet connections, and then gives a popup asking you if you want to allow or disallow it, and/or whatever else Windows Firewall allows you to config that might be useful.
This is a feature that should be easy to add to the program. We don’t need a “temp” option because it’s not something that exists in windows firewall itself. Our temp will be block, and then simply remove it/unblock in the program and thus windows firewall.
I know there’s other options that do this, but yours is the only one that does the base of what we all want to compliment Windows firewall, save that one necessary feature. Thanks.
Like the program. I made a guide how to use FAB. Hope you like it.
Web Link …
Of course NO
This is just what I’m looking for: great. One question: if I produce a blocking rule using FAB, will this rule be removed from the windows firewall if FAB is removed?
No sorting? Would be happy, add it to Status, Name and Locations.
Sorry our mistake , corrected – Firewall App Blocker has no Xp support
I’m getting Error message: Operating system not supported, despite being on XP sp3 which your program says it supports.
We have already shared correct SHA1 hash value for FAB v1.4 , We give only .exe hash values not the z.p files
What is the correct SHA1 hash value for FAB v1.4? The one by the download button is wrong…
Here is a script that will block multiple apps through the firewall (for free)

We can try to code it , thanks
Would it be possible to make a Drag/Drop “Allow” rule instead of “Block” rules only? With your current implementation, it is required to run the Windows Firewall in “Allow All” mode and only block applications that should be blocked. Most of the time, we use the Firewall in “Block All” mode and only allow applications that should use the network. Maybe for your next update?
There is no such Problem , for 1 second FAB disable Firewall and enable it again – 1 second must be not a problem , FAB need Windows Firewall , Firewall App blocker” runs properly if your Windows firewall not disabled and run properly.
We will check the possibility of the saving Snapshots , thanks for your comment
It is also not a great idea to reset Windows Firewall to the default, it may be better to allow saving “Snapshots” of the Firewall configuration and let you restore such snapshots.
Do you have a place to report bugs? If you block the NetLimiter4 trial installer with this application it will cause the Windows Firewall service to shutdown. If you remove the rule it will start up again. All this in Windows 10.
Gracias por aportar soluciones verdaderamente buenas!!!! 100% recomendado todo lo que hay aqui en esta web!!!!
