Hi there,

This is Wil, one of the independent advisor, an expert with Windows 10 and a fellow Windows 10 user like you. I understand your concern about blocking a program in Windows Defender Firewall.

You can block or allow an app on the Windows Defender Firewall. Kindly follow the steps below.

1. Access Control Panel by pressing Windows key + R, type control, and press enter.
2. Click on System and Security and click on Windows Defender Firewall
3. On Windows Defender Firewall, click the "Allow an app or feature through Windows Defender Firewall"
4. On the list of apps, uncheck both checkboxes to block the application and check it to allow the application.

Open the Run window (Windows key + R).
Type "WF.msc". This should open up Windows Defender Firewall with Advanced Security.
Click on Outbound Rules in the left sidebar.
SelectNew Rule in the right sidebar.
Check ifProgram selected, click on Next.
Browse and locate your executable. (.exe).
Select Block the connection. Click Next.
Let the checkboxes remain as is if you want to block the connection everywhere regardless of the network it is connected to. Click Next.
Write an appropriate Name and Description so you know which program is being blocked by the rule. (Will save confusion later when trying to unblock the program.)
Click onFinish.

If you wish to unblock the connection, simply select and delete (R-Click + Delete, or Del on the keyboard) the rule.

This is the general solution to block connections of the program to the internet (and other computers on the network). If you want to block incoming connections to the program, create a similar rule in theInbound rules section (Left sidebar).
