I have an application running on Windows 7 that I would like to continue using but prevent it from accessing the Internet. How do I do this? Do I use some kind of local policy, etc?

The app would sometime phone home and I need to stop this but continue using the app.

This question came from our site for system and network administrators.

More of an SU question but here's the answer:

Windows 7 includes an application-level firewall which you can use to restrict network traffic on a per-program basis.

To do this:

  • Go to Start -> Control Panel -> Firewall
  • Pick 'Advanced Settings' on the left bar
  • Click 'Outbound Rules' on the left, then 'New Rule' on the right
  • Select 'Program', Next
  • Browse to the program's .exe, Next
  • Select 'Block the connection', Next
  • Leave all the boxes ticked, Next
  • Give the rule a name, Finish

Job done ;)

I just followed your instructions. Perfect! – raj Feb 22 '10 at 6:32

If you do not want to make a firewall rule for every program, use this plug in for the Vista/W7 firewall, its an outbound active firewall.

I use the free version
