Blocking a program from accessing the internet using Windows Firewall is a straightforward process. You do this by creating an outbound rule that denies the program’s connection. Here’s how to do it step by step.

1. Open Windows Defender Firewall with Advanced Security
- Press
Windows S
, type Windows Defender Firewall, and click on Windows Defender Firewall. - In the left pane, click on Advanced settings.
- This opens the Windows Defender Firewall with Advanced Security window.
If prompted by User Account Control (UAC), click Yes to continue.
2. Create a New Outbound Rule
Since you want to block a program from reaching the internet, you need to create an outbound rule:

- In the left pane, click Outbound Rules.
- In the right pane, click New Rule… This starts the New Outbound Rule Wizard.
3. Set Up the Rule for the Program
Follow the wizard with these settings:
Step 1: Rule Type
- Select Program → Click Next
Step 2: Program Path
- Choose This program path:
- Click Browse and locate the
.exe
file of the program you want to block (e.g.,C:\Program Files\SomeApp\app.exe
) - Click Next
Tip: If you're not sure where the program is installed, right-click its shortcut → Properties → look at the "Target" field.
![]()
Step 3: Action
- Select Block the connection → Click Next
Step 4: Profile
- Leave all three boxes checked (Domain, Private, Public) unless you want the rule to apply only in specific network environments.
- Click Next
Step 5: Name and Description
- Give the rule a clear name (e.g., Block Chrome Internet Access)
- Optionally add a description like Prevents Chrome from connecting to the internet
- Click Finish
4. (Optional) Verify or Modify the Rule
- After creation, you’ll see your rule listed under Outbound Rules.
- You can double-click it to edit, disable, or check its status.
- To re-enable internet access later, just disable or delete the rule.
Notes and Tips
- This method blocks both TCP and UDP traffic for the program.
- Some programs may have multiple
.exe
files (e.g., helper tools or updaters). You may need to block them separately. - Administrator privileges are required to create firewall rules.
- Antivirus or third-party firewalls might interfere—ensure Windows Firewall is active.
Blocking a program this way doesn’t stop it from running—it just cuts its internet access. Useful for stopping bloatware, telemetry, or apps that phone home.
Basically, just set up an outbound block rule for the .exe
, and you're done.
