Thanks for using the Microsoft Answers Forum.
There may be a couple of explanations for this problem which I have experienced personally.
The first possibility is that the drivers for the touch device need to be updated or reinstalled. This can be done through the manufacturer’s website for device driver for your device.
The second option is that you need to disable the pointing device while you are typing. If you are using an external mouse please go into the touchpad properties and disable the onboard device so that when you are typing your palm or thumbs are not hitting the pad while using the keyboard for typing.
Try these suggestions and let us know what you find.

As stated above *The first possibility is that the drivers for the touch device need to be updated or reinstalled..
My son the computer guru says that the touch device driver needs to be installed on mine.
