How to Disable Touchpad When a Mouse is Connected

In this instance, I’m using a Windows 10 laptop with a precision touchpad.

Follow these steps to automatically disable the touchpad of your Windows 10 laptop when an external mouse is connected:

Go to touchpad settings.

Uncheck the option “Leave touchpad on when a mouse is connected.”

That’s it.

Note: To switch to the default setting (which is enable), select the option above.

Alternate Method

Launch Registry Editor. I suggest backing up the Registry before proceeding.

Go to HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > PrecisionTouchPad.

In the right pane, you can see LeaveOnWithMouse DWORD. Double-click it.

Provide ffffffff (to enable) or 0 (to disable) in the Value data field.

Hit the OK button.

Restart your PC.

That’s all.
