How to Turn On or Off Leave Touchpad On when Mouse Connected in Windows 11

This tutorial shows you how to turn on or off the touchpad on your Windows 11 computer when a mouse is connected.

Why This Matters

If your laptop has a built-in touchpad and you use an external USB or Bluetooth mouse, you can make Windows automatically turn off the touchpad when the mouse connects. This stops accidental touchpad touches while you work.

What Happens

When you enable this setting, your touchpad will turn off automatically when you plug in or connect a mouse. When you disconnect the mouse, the touchpad turns back on.
