Windows only: Most laptop owners have experienced the frustrations of an unpredictable cursor when your wrist grazes the touchpad. Free, open-source utility TouchFreeze disables your touchpad as soon as you start typing, re-enables it when you stop.

Although you can always go to your Control Panel and then to Mouse Properties to disable your touchpad the long way, it still means you have to turn it back on when you'd like to use it. TouchFreeze makes things a little easier, and as long as you're not doing any heavy photo editing that might necessitate the simultaneous use of the touch pad and keys, this should be a winner of a program for you.

TouchFreeze sits in your system tray and simply turns off the touchpad when you start typing. It's a dead simple, free, and open-source program that works with Windows 2000, Windows XP, Windows Vista, Windows Server 2003/2008, Windows Server 2008, and Windows 7.
