How to Block Internet Access to an App in Windows 11: A Step-by-Step Guide

Learning how to block internet access to an app in Windows 11 is easier than you might think. It only takes a few clicks in the Windows Firewall settings, and you can prevent any app from accessing the internet. This can help you save on data usage, protect your privacy, or prevent distractions from online notifications.

How to Block Internet Access to an App in Windows 11

In this section, we’ll walk you through the steps to block internet access to a specific app. By the end, you’ll have complete control over which apps can connect to the web.

Step 1: Open Windows Firewall

First, open the Control Panel and navigate to Windows Defender Firewall.

This is your gateway to controlling which apps can access the internet. It’s like the bouncer at a club, letting in only those on the list.

Step 2: Advanced Settings

Next, click on the "Advanced Settings" link on the left-hand side.

This opens up more detailed options, giving you a deeper level of control over your system’s security settings. Think of this as going backstage where all the important decisions are made.

Step 3: Create a New Outbound Rule

Now, click on "Outbound Rules" and then choose "New Rule" from the right-hand sidebar.

Outbound rules are what control the data leaving your computer. By setting up a new rule, you’re essentially putting up a "No Exit" sign for that specific app.

Step 4: Choose the Program

Select "Program" and click "Next," then browse and select the app you want to block.

By specifying the app, you’re telling the firewall exactly which guest you want to keep outside. It’s like giving the bouncer your friend’s name who forgot their ID.

Step 5: Block the Connection

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

This step is the heart of it all. It’s like locking a door to keep that app from wandering out into the wild internet.

Step 6: Apply the Rule

Finally, name your rule and click "Finish."

Make sure the rule is enabled so that it starts working immediately. This is like writing the app’s name in the bouncer’s do-not-admit list.

Once you complete these steps, the app will no longer be able to access the internet. You’ll notice that it stops sending or receiving any data, effectively isolating it from the online world.

Tips for Blocking Internet Access to an App in Windows 11

  • Double-Check the App: Make sure you’ve selected the correct executable file for the app. Some apps have multiple files.
  • Test the Rule: After setting up the rule, open the app and see if it can still access the internet to confirm that your settings work.
  • Keep it Enabled: Ensure the rule is enabled at all times unless you want to grant temporary access.
  • Use Descriptive Names: When naming your rule, use a name that helps you remember why you created it.
  • Know When to Update: If the app updates frequently, you may need to update your rule to include the new executable.
