I attempted to install a Synaptics driver from an earlier model XPS which came with Windows 8.1. Setting this to Low has not helped in this case.

I gathered from my reading that earlier versions of Windows 10 did offer the "Turn off TouchPad While Typing" or its equivalent, as several articles I cam across direct users to that setting under Mouse and Trackpad in Settings, but that later versions have apparently eliminated that setting in favor of the Trackpad Sensitivity setting. Any suggestions on how to resolve this problem? I am unable to find any setting that resembles the "Disable Touchpad While Typing" setting I have used in the past to resolve this issue. There is a Touchpad Sensitivity setting, which we set to Low, yet this has not helped the issue. On this laptop there is no such setting anywhere in Touchpad or Keyboard settings.

I read of a "Touchpad Delay" setting under Settings > Touchpad, with a recommendation to set it to Long to resolve this issue.

The client complained of the cursor jumping around when typing. On this laptop the touchpad is managed by Windows 10, there is no 3rd party driver for the touchpad. There was a BIOS update and several other updates from Dell that installed with no errors. I performed the initial setup, and installed all available Windows updates and also all available Dell driver and firmware updates. A client just purchased a Dell XPS 15" Windows 10 laptop.
