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!

The main purpose of the software is not to disable the Firewall.
Hi. There are 2 IPsec processes related to firewalling that aren’t stopped when disabling firewall.
Agente de directiva IPsec (policyagent)
Motor de filtrado de base (bfe)
Unfortunately no
Can I use this to block a driver? A internal keyboard driver for example
Nice utility. Save me a lot of time going typing scripts for the firewall. It would be nice if dll fille blocking capabilities can be added to the software
Hi, Thank you for the Firewall App Blocker, that makes easy to create firewall rules, IF the software can create both In/Outbound rule at the same will be very helpfully.
Thank you.
Eric
1. No but all settings will valid
2. How do I minimize the FAB program to the system tray? , for the FAB it seems unnecessary but we may use this option next version.
Hello!
I have two (2) simple questions about the ‘Firewall App Blocker’ program, in Windows 10:
1. If I close the F.A.B. program (Specifically, with the [X] at the top right), does FAB continue to run in the background?
2. How do I minimize the FAB program to the system tray?
Cheers~
Got it sorted. It was a software (Glasswire) that kept resetting Firewall App Blocker.
Anyway, how do you stop KMS Server connection from being blocked? I have to go to Default Mode for connection and then back to Whitelist Mode. Added the service KMSSS.exe but that doesn’t work (i.e. doesn’t connect to server).
Thank you
why you want to start it with system start ?
It is recommended to add, with the system self-starting, in the system tray
It seems there is something wrong with your system, it can be a firewall problem . please reset your firewall or if you use any other security software disable it.
When I restart the PC the program returns back to default mode from whiltelist mode. It did not do this before. Please advise.
We have tested it on Win7 Pro x64.After enable white list Mode we added
C:\Program Files (x86)\ ozilla Firefox \firefox.exe
to the Outbound Rules list. Firefox connected to the internet without any problems.

There may have been a problem with the firewall rules on your system. If you have an important setting in the firewall rules, you can back up the settings and try to reset the windows firewall rules.
If the problem still persists, you can add processes which running in the background one by one to the fab list and check the status.
W7pro, FAB in Whitelist Mode, Firefox Outgoing enabled: W7 says "WLAN connected, but no Internet Access". Firefox has also no Internet connection.
Disabling Whitelist Mode, everything works.
Any hint?
This means White list mode works perfect, Just disable white list mode to use Vpn then enable it again
