    1. Blocking ports using Windows Firewall
      Select New Rule from the Actions pane. Select Port from the Rule Type listing. Select TCP or UDP, and specify the ports, or a port range (e.g. 445, or 137-139). Select block the connection.

    2. You block ports using a firewall, not Registry edits. Have a look at http://support.microsoft.com/kb/875357 .

      The “Internet” doesn’t use just one port; it all depends upon what you are doing. If you mean web browsing, that’s ports 80 and 443 by default, though other ports are sometimes used.
