When using your laptop, you may find that you occasionally get spurious cursor movement because you accidentally brush across the touchpad. I prefer using a mouse to the touchpad, so I'm at no disadvantage in disabling it and I therefore avoid unintentional cursor movement. Disabling a laptop's touchpad is a simple exercise, once you know where to go.
Go to Start | Settings and click Devices. On the left side, click Mouse & Touchpad. Scroll down and at the bottom click the "Additional Mouse Options" link. (See Figure 1.)

This brings up a new window. Click the "Device Settings" tab, ensure your mouse is selected in the Devices window, and check the box labeled "Disable internal point device when external USB pointing device is attached." (See Figure 2.)

Don't be thrown off by the mention of a "USB pointing device." I use a Bluetooth mouse, and this still works. OK your way out, and now your touchpad is disabled.
