Blocking a program in the Windows 11 firewall is a handy skill to have if you want to control what software can access the internet from your computer. By following a few simple steps, you can easily prevent specific programs from connecting online, offering you more security and peace of mind. This guide will walk you through the process in detail, ensuring you have the knowledge to manage your computer’s firewall settings efficiently.
How to Block a Program in Firewall Windows 11
To block a program in the Windows 11 firewall, you need to add a rule that restricts internet access for the chosen application. Here’s exactly how to do it:
Step 1: Open Windows Security
First, click the Start menu and type “Windows Security” into the search bar, then select it.
Windows Security is your go-to hub for all things safety-related on your PC. By opening it, you gain access to the firewall settings you need to create rules for internet access.
Step 2: Access Firewall & Network Protection
Navigate to the “Firewall & Network Protection” option once you’re in Windows Security.
This section of Windows Security deals specifically with network access and is where you can adjust the firewall settings. It’s like the control center for your computer’s internet shields.
Step 3: Open Advanced Settings
Click on “Advanced settings,” usually found at the bottom of the Firewall & Network Protection window.
The Advanced settings page is where you have the power to tweak the firewall rules precisely. You can create inbound or outbound rules depending on what you need.
Step 4: Create a New Outbound Rule
Choose “Outbound Rules” from the left-hand menu and then select “New Rule” from the right-hand Actions pane.
Outbound rules are essential for blocking programs from sending data out to the internet. Creating a new rule here will let you stop a specific app from making any online connections.
Step 5: Select the Program and Block the Connection
In the new rule wizard, select “Program” and then browse to find the executable file of the program you want to block. Proceed to choose “Block the connection.”
By specifying the program, you’re targeting exactly what should be restricted. Blocking the connection ensures that the app can’t send or receive data over the net, effectively putting a lid on its internet activities.
Once you’ve blocked a program with the firewall, it won’t be able to connect to the internet. This means it can’t send or receive data from online sources, ensuring it doesn’t pull or push info without your consent. It’s a great way to safeguard your system from potentially risky software connections.
