How to Disable Touchpad on Laptops – Full Solution
If you use an external pointing device with your Windows 10 laptop, you probably don’t want accidental touches or presses on the built-in touchpad to register. Disabling it can help. But rarely, the options that let you disable the touchpad don’t work or seem to be missing.
If you are unable to disable the touchpad in Windows 10, you can try alternative settings, registry hacks, and third-party software to fix the issue.
Tip: Your laptop may have a special key or switch that you can use to disable the touchpad. Try checking (and using) this before you begin.
