Best answer as chosen by user IsaAl122: The controls for the mouse are in the Control Panel

Go to the Mouse applet of the Control Panel. That's where all the mouse controls are. It's not clear what you mean by "reverse scrolling", but the mouse applet has a number of controls you can change. If your current mouse doesn't have what you want, you can always buy fancier ones that come with their own more sophisticated controls.
Good luck.
