By default Windows Firewall is set to on.  This means that many programs may not be able to communicate through the firewall until they have been added to the safe list.  To add a program to the safe list click Allow a program or feature through Windows Firewall on the left panel of the screen shown above. You will be taken to the following page.

From the selections you see that you can allow certain programs to through the firewall depending on which of the three networks you have labeled your network environment. The abilities listed on the Customize Settings page include an option to block all incoming connections, including those in the list of allowed programs.  This option is good for when you are on a public network as it block any attempt to connect to your system by an outside intruder.  You will still be able to browse the web and send emails and instant messages.  Also there is the option to have windows Notify me when Windows Firewall blocks a new program. This informs the user that the firewall is blocking the access and allows the user to select if they would like to unblock the program for better functionallity.
