What is a firewall?
A firewall controls network traffic, allowing or blocking it according to rules you specify (rather like a doorman at a nightclub, with rules on who to allow entry to). This can either be a special program running on your computer ("software firewall") or a separate box connected between your computer and the Internet ("hardware or firmware firewall"). How good is Windows' firewall?
Microsoft provided a very simple firewall with Windows 2000 which was then significantly improved with Windows XP Service Pack 2. This version can provide good protection from incoming attacks but cannot be relied upon to control outgoing traffic. Older versions of Windows (95, 98, ME, NT) have no firewall. How can I test my firewall?

First, You Go to > Start Menu > Control Panel > Windows Firewall > then you can Change Settings/Enable or disable.
