I have a similar problem with the touchpad on my PC. It is not the same PC but it is having the same issue.
I didn't choose this PC, it is a disability aid PC. The zoom function is making it very hard for me to do my work as a student with this computer. I want to turn it off, but there doesn't seem to be a way of doing it. I would have thought that this oversight
is a major blip on accessibility, since it is making my PC highly inaccessible and causing me increasing levels of frustration trying to do basic tasks.
This is a computer, it is not a mobile phone. It doesn't need to have touchscreen functions or at least, it needs to have the option to turn them off and operate the computer as a computer for those of us who have actual legitimate needs for it rather than
just checking facebook. We are not all touch screen people. Some of us liked our computers to behave as computers.
It is amazing to me that there is no way to fix this. The touchpad on this PC is driving me crazy, as is the whole setup of Windows 8.1.
Do something about it please, Microsoft. Introducing it into Windows 10 won't help me because all my disability software is installed on this PC and so I can't upgrade.
