When you need all your computers resources for yourself, LanBuster lets you easily turn on or off file sharing. LanBuster runs in the system tray, and signals with the icon color whether the LAN has been disabled or not. A double click on the icon in the system tray is all that is needed to control the state of your file sharing. Your Internet connection is not affected. LanBuster can be useful for everything from MP3 encoding, CD burning to online gaming.
