Mouse move too fast how to adjust?

Method One: Start-> Control Panel-> mouse-> pointer options

If it's a razer-like mouse, then use the official drive to adjust.

Method Two: Start-settings-Control Panel-Mouse (if another view is the printer and other hardware-mouse)-pointer options The first item can be adjusted to move speed

Method Three: Point left bottom Corner "start"--select "Control Panel"--"printer and other Hardware"

--"Mouse"--"pointer Options"--there is a slider that "chooses the pointer to move speed",

Move the dots to the "slow" side, preferably in front of the "Improve pointer accuracy".
