Of course, you can manually disable touchpad, but a small utility called Touchpad Blocker helps you differently. The software helps the user to type text as fast as possible by locking mouse events during a small period after any keys were pressed.

Touchpad Blocker is a must have software for notebook owners who prefer to use touchpad instead of mouse or other pointing devices. You can download Touchpad Blocker at source (supports Any 32 or 64 bit version Windows)
