How to disable touchpad when external mouse is connected

Question

In How to disable my netbook's touchpad when a usb mouse is connected I could not find an answer for my question.

Some laptops have drivers that automatically disable touchpad when an external mouse is connected. My three-years-old Toshiba's drivers do not have such option. Is there another way to do this in Windows 7? Answers to the mentioned question say to use the driver's option. I don't have that driver and thus don't have such option. What can I do?

Solution

This doesn't apply to Windows 7, but Windows 8 & 10 have a built in option to disable the touchpad when a mouse is connected.

Open the Windows settings app (Ctrl+I), navigate to Devices → Touchpad, and uncheck Leave touchpad on when a mouse is connected

I'm looking for third-party software for this too; Acer's India tech support took 20 minutes to tell m e they THINK it's synaoptics and they refuse to support Windows 7. "PowerSwitch" is great for laptops and I'm hoping to find a third party program like that but for the trackpad ONLY when mouse is hooked up.

The suggested duplicates do not appear to provide a Win 7 solution if the driver doesn't support this feature, as is the case here.
