Windows 10: touchpad resizing

Is there any way to shrink the touchpad active area (like cropping a photo). I ask because I keep inadvertently touching the touchpad with the lower part of my hands while typing, thus relocating the cursor.

I want to disable touchpad on Dell laptop


Hello everyone,
My laptop's touchpad works and I don't want it to, because I prefer a mouse. It's a Dell Inspiron 11 3000 series on windows 10 OS.

What I have tried that hasn't worked:

• start<settings<devices<mouse & touchpad<additional mouse options. This opens a window called Mouse Options which has 5 tabs up top, none of which involve the touchpad. The Hardware tab shows 2 devices: the mouse itself, and the USB. No touchpad there.
• windows key+x<mobility center. No touchpad to be found.
• various function keys. No options for touchpad on/off.
• device manager<mice and other pointing devices. Again, only the mouse and usb show up. It appears the touchpad is working without a driver, which is a little spooky.

Any other suggestions? I could try downloading a third party driver, but that seems like a step in the wrong direction.
Thanks

 

TouchPad problem


see attached screenshot of the keys after I re ran the scan

so i assume next steps are to have that program open that you suggested whilst using the laptop and then when the touchpad gets disabled to check if the keys have changed?

 

turn off touchpad

Thanks for trying I downloaded driver for touchpad, followed the steps you listed but it did not solve the problem - When I get to the last tab for the software, there is no checkbox for "disable touchpad if mouse is attached." I can completely disable the
touchpad by system, and you, advised against this so at least I had the warning not to completely disable touchpad. I have tried the other options suggested but to no avail. Frustrating!
