3. In the Windows Defender Firewall window, look at the left sidebar.
4. Click on Advanced settings. This action will open the Windows Defender Firewall with Advanced Security window.
5. In the Advanced Security window, you will see options for Inbound Rules and Outbound Rules on the left side.

Take a moment to familiarize yourself with the interface to avoid confusion later. Remember, you can always revert changes if needed. However, be cautious when modifying firewall settings, as improper changes can affect your system’s security.

Troubleshooting & Verification

If you encounter issues accessing advanced settings, ensure you have administrative privileges. Check if your Windows Firewall is enabled and functioning correctly. Restart your computer to apply any changes. Additionally, verify that your Windows version supports the features you are trying to access, as older versions may have limitations.

Step 3: Create a New Outbound Rule

1. Open the Windows Defender Firewall with Advanced Security by searching for it in the Start menu.
2. In the Advanced Security window, locate and click on ‘Outbound Rules’ in the left pane.
3. In the right pane, click on ‘New Rule…’ to launch the New Outbound Rule Wizard.
4. In the wizard, select ‘Program’ as the rule type to block a specific application and click ‘Next’.
5. Click on ‘This program path:’ and enter the full path of the application you wish to block. For example,

   C:\Program Files\YourApp\YourApp.exe

   .

6. Click ‘Next’ to proceed to the action settings.
7. Select ‘Block the connection’ and click ‘Next’.
8. On the Profile page, choose when the rule applies (Domain, Private, Public) and click ‘Next’.
9. Finally, give your rule a name and an optional description, then click ‘Finish’ to create the rule.

Troubleshooting & Verification

If the outbound rule does not seem to work, verify that the rule is enabled in the Windows Firewall settings. Check for any conflicting rules that may allow internet access. Additionally, ensure that the application is correctly identified in the rule. Restart the application and test the internet connection again.

Step 4: Specify the Program to Block

1. In the New Outbound Rule Wizard, select the option labeled ‘This program path:’.
2. Click on the ‘Browse’ button to open a file explorer window.
3. Navigate to the installation directory of the application you want to block. This is typically found in C:\Program Files or C:\Program Files (x86).
4. Locate the executable file (.exe) of the application. If you are unsure which file to select, right-click the application shortcut on your desktop or in the Start menu, and choose ‘Open file location’ to find the correct path.
5. Once you find the executable file, select it and click ‘Open’.
6. After the program path is specified, click ‘Next’ to proceed to the next step in the wizard.

Ensure you select the correct executable file to avoid blocking the wrong application. This will help maintain the functionality of other programs on your system.

Troubleshooting & Verification

If the program is not blocking as expected, ensure that you have selected the correct executable file. Check for any conflicting firewall rules or security software that may override your settings. Restart your computer after making changes to ensure they take effect. Verify the app’s internet access using a browser or network tool.

Step 5: Choose the Action to Block

1. After configuring the program and protocol in the previous steps, you will reach the “Action” page of the wizard.
2. Here, you will see options for how to handle the connection. Select the option labeled ‘Block the connection’.
3. Once you have made your selection, click on the ‘Next’ button to proceed to the next step.
4. Review the summary of the rule you are creating to ensure it reflects your intentions accurately.
5. Consider creating a backup of your current settings before finalizing the rule, as this will allow you to revert back if needed.
6. Remember that blocking the connection may affect the application’s functionality, so proceed with caution.

Troubleshooting & Verification

If you encounter issues while choosing the action to block, ensure that you have administrative privileges. Check if the application is running and verify that your firewall settings are correctly configured. Restart your computer to apply changes, and test the app to confirm that internet access has been successfully blocked.

Step 6: Finalize the Rule Setup

1. Specify the Rule Application: Choose when the rule applies by selecting the appropriate network types. You can select from Domain, Private, or Public. This setting determines under which network conditions the rule will be enforced.
2. Name the Rule: Enter a descriptive name for your rule in the designated field. This name should be recognizable and relevant to the application you are blocking, making it easier to identify in the future.
3. Add a Description (Optional): For added clarity, you may include a brief description of the rule. This can help you remember the purpose of the rule later on.
4. Finish the Setup: Click the ‘Finish’ button to create the rule. This action will finalize your settings and add the new outbound rule to the Outbound Rules section.

After creating the rule, it is advisable to test the application to ensure that its internet access is successfully blocked. Remember to keep the rule name recognizable for easy future reference.

Troubleshooting & Verification

If the rule isn’t working as expected, ensure that the correct application path is specified. Check for any conflicting rules that may allow access. Additionally, verify that the rule is enabled and applied to the correct network profile (Domain, Private, or Public). Restart your computer to apply changes effectively.
