No response on the Dell Support page and haven't had an opportunity to call Dell (time difference). I reinstalled Windows 10, fresh install, on a Dell XPS 13 laptop (9350...current mondel) and can't remember if it just used the Windows 10 drivers or if there are drivers that improve functionality (i.e. who makes the touchpad and what model if applicable). If anyone knows, please let me know. For some reason, I can't seem to find an option to enable to increase horizontal scrolling in Windows 10. Vertical scrolling works fine.
