Windows has had a built in firewall since Windows XP, and maintained that feature during transitions to Vista, Windows 7, and Windows 8. The goal of the firewall is to enhance security for users, particularly those who are not thoroughly experienced with potential online hazards. Some more advanced users consider the Windows firewall to be a bit too cumbersome. This guide will give you a quick rundown on the firewall and when it should and should not be used.
Different Version of the Built In Firewall
The Windows built in firewall has seen steady evolution since it began in XP. In a base install of Windows XP, the firewall blocks only inbound connections that have not been initiated by your computer, and the setting is turned off by default. Service Pack 2, however, turns on the firewall default and also gives administrators group control over the firewall. Vista saw additional filters put on the firewall, and Windows 7 and 8 have worked to provide the user with more control over what information you allow. This includes being able to designate different connections as either a home network, a work network, or a public network.
