First, I assume that manufacturers can(and sometimes do) override default settings.
That being said, on the three unaltered (default set-up) systems I've checked running Windows 10 the settings are as follows:
Primary Button: Left
Mouse Wheel Scrolls: Multiple lines at a time (as opposed to a screen at a time)
How many lines to scroll: 3
Inactive window scroll: On
These are all of the settings that are in the literal "settings" area of Windows 10. Under the control panel you can gain access to more mouse settings, for instance I have a specific driver downloaded for the Comfort Optical Mouse 3000 by Microsoft. You will also find settings separated into tabs for Buttons, Pointers, Pointer Options, Wheel, Hardware, and any device specific driver should be represented by a tab here as well.
Double Click Speed: . . . . . . | . . . . (5th notch from the right)
Click Lock: Off
Enable pointer shadow: Off
Pointer Speed: . . . . . | . . . . . (Dead center notch)
Enhance pointer precision: On
Snap To: Off
Display pointer trails: Off
Hide pointer while typing: On
Show pointer location on CTRL: Off
Vertical Scrolling: 3 lines
Horizontal Scrolling: 3 characters (if you have a device supporting horizontal scrolling)
Hardware settings and Driver tabs are completely dependent on the devices(mice) you use and drivers you download.
