How to Disable a Mouse Touchpad in Windows 7
A touchpad on a laptop computer can be an advantage for users looking for an intuitive way to navigate their desktop. But some users prefer a standard peripheral mouse due to personal or professional preferences. When using a peripheral mouse, the touchpad stops being an advantage and starts becoming a liability. An accidental mouse click or movement from a touchpad you forgot was active can delete or change important documents. To stay on the safe side, you can disable your Windows 7 touchpad with a few clicks of your preferred peripheral mouse.
Click on "Control Panel."
Click on the Hardware tab if no tab marked "Devices" is present. Click on your mouse touchpad in the window. Click "Properties."
Click "Change Settings."
Click on the tab marked "Driver."
Click "Disable." Click "Yes" in the window that appears.
Click "OK." Restart your computer when prompted to save and enact your changes.
