What are the default mouse settings on Windows 10?

Solution 1:

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:

Mouse

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.

Buttons

Configuration:           Right-handed

Double Click Speed:      . . . . . . | . . . .   (5th notch from the right) 

Click Lock:              Off

Pointers

Scheme:                  (None)

Enable pointer shadow:   Off

Pointer Options

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

Wheel

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.

Solution 2:

Defaults

• Vertical Scrolling is 3
• Horizontal Scrolling is 3

Registry File

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]
"WheelScrollChars"="3"
"WheelScrollLines"="3"

Solution 3:

I recently reinstalled Windows 10 and remembered to export all the defaults from the registry:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Mouse]
"ActiveWindowTracking"=dword:00000000
"Beep"="No"
"DoubleClickHeight"="4"
"DoubleClickSpeed"="500"
"DoubleClickWidth"="4"
"ExtendedSounds"="No"
"MouseHoverHeight"="4"
"MouseHoverTime"="400"
"MouseHoverWidth"="4"
"MouseSensitivity"="10"
"MouseSpeed"="1"
"MouseThreshold1"="6"
"MouseThreshold2"="10"
"MouseTrails"="0"
"SmoothMouseXCurve"=hex:00,00,00,00,00,00,00,00,15,6e,00,00,00,00,00,00,00,40,\
  01,00,00,00,00,00,29,dc,03,00,00,00,00,00,00,00,28,00,00,00,00,00
"SmoothMouseYCurve"=hex:00,00,00,00,00,00,00,00,fd,11,01,00,00,00,00,00,00,24,\
  04,00,00,00,00,00,00,fc,12,00,00,00,00,00,00,c0,bb,01,00,00,00,00
"SnapToDefaultButton"="0"
"SwapMouseButtons"="0"

You can save this into a .reg file to import it or just manually change the ones you want via regedit.
