General Tab: The General tab provides access to the main three configuration options as shown
below.
◦
On (Recommended)
◦
Don’t allow exceptions

Off (Not Recommended)
When you select Don't allow exceptions, Windows Firewall blocks all requests to connect to your
computer, including those from programs or services on the Exceptions tab. The firewall also blocks
file and printer sharing and discovery of network devices
Using Windows Firewall with no exceptions is useful when connecting to a public network. This
setting can help to protect your computer by blocking all attempts to connect to your computer.
When you use Windows Firewall with no exceptions, you can still view Web pages, send and
receive e-mail, or use an instant messaging program.

is open.
