How to Block Program in Firewall Windows 11

Blocking a program through Windows 11 Firewall helps protect your computer from unwanted internet access. The steps below guide you through the process, ensuring your selected program is effectively blocked from online activities.

Step 1: Open Windows Security

Click on the Start menu and search for "Windows Security."

By typing "Windows Security" into the search bar, you’ll quickly find the app. This is your hub for all security-related settings.

Step 2: Access Firewall & Network Protection

Once inside Windows Security, select "Firewall & Network Protection."

This section contains all the tools you need to manage and configure the firewall settings.

Step 3: Open Advanced Settings

Click on "Advanced settings" to open the Windows Firewall with Advanced Security.

This opens a more detailed set of options where you can create new rules for your firewall.

Step 4: Create a New Outbound Rule

Select "Outbound Rules" and then click "New Rule."

Outbound rules control how your computer connects to the internet, and creating a new one helps you block specific programs.

Step 5: Choose Program

Select the "Program" option and click "Next."

You’ll specify which program you want to block, ensuring it can’t communicate with the internet.

Step 6: Find the Program Path

Browse to find the executable (.exe) file of the program you want to block and click "Next."

Locating the correct file is crucial, as this tells the firewall exactly which program to restrict.

Step 7: Block the Connection

Choose "Block the connection" and click "Next."

This setting ensures that the program is effectively cut off from internet access.

Step 8: Apply Rule to Profiles

Select when this rule applies: Domain, Private, or Public, then click "Next."

These profiles determine under what network conditions your rule will be active.

Step 9: Name the Rule

Give your new rule a name and click "Finish."

Naming the rule helps you easily identify it later if you need to make changes.

After completing these steps, the program you’ve selected will be blocked from accessing the internet, enhancing your computer’s security.
