WizMouse is a free utility that lets you emulate this great feature on your Windows desktop, and reduce the time and effort you have to put on your tasks.
WizMouse works in a really simple way. After you install it, the background scroll works from the startup, and you can see the program icon on the system tray.
This tool also lets you enable scrolling for those applications that in principle don't have it enabled. You can also change the scrolling speed as you like.
