The firewall included in Windows 10 is pretty good for basic use and does a credible job of protecting you from external threats. It can block access into or out of your computer and offers an array of controls you can tailor to how you use your computer. One of the key tasks you will want to get to grips with is to block a program in Windows Firewall. Here’s how to do it.
Why would you want to block a program in your firewall? More and more programs have online elements that download updates, ads or allow online purchases. They can also upload your data, sometimes without you knowing. Controlling how and when they connect to the internet allows you to decide how they operate. It also offers an essential layer of security for your computer.
Block a program in Windows Firewall
Blocking a program within Windows Firewall is pretty straightforward. Just don’t be put off by the interface as there is a lot going on.
1. Navigate to Control Panel, System and Security, Windows Firewall and Advanced Settings.
2. Highlight Outbound Rules in the left pane.
3. Select New Rule in the right pane and select Program from the next box.
4. Select ‘This program path:’ and select the program you want to block. Then click Next.
5. Select ‘Block the connection’ and then click Next.
6. Select all network types in the next window and click Next.
7. Name it something meaningful. I tend to add the name of the program into the title so I can tell at a glance.
8. Right click your new rule and select Properties.
9. Click Settings next to Services and select ‘Apply to this service’.
10. Select the service associated with the program you’re blocking. Not all programs install services so don’t worry if there isn’t a corresponding service. Click OK either way.
That’s it. You have now blocked a program in Windows Firewall. If you want to temporarily allow access for an update, simply right click and disable the rule. Then enable it once the operation is complete.
