Windows – How to enable OSX ‘inverted’ scrolling on the keyboard (win7)

After almost two years, I FINALLY found the solution!!

As explained in this article, it's as simple as editing the registry and adding a DWORD at HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh with name UseScrollCursor and value 0 and restarting SynTPEnh.exe.

This fixed the problem in Steam and Zune flawlessly, with both edge scrolling and two-finger scrolling.

If your keyboard is near your mouse, you can hold the shift key down while you operate the scroll wheel. The window should scroll left and right.

Of course, the left and right arrow keys will scroll the contents of a window left or right in short steps.

Some mouse devices have additional controls and a software driver designed for Macs (Logitech, for example). Those drivers often add a settings pane to the System Preferences application that allow you to assign functions / keystrokes to those buttons. For example, a mouse I have used had a scroll wheel that you could move left or right, activating a separate switch in each of those two directions. Using the settings pane, I was able to set the driver to scroll left or right by activating the left-right function of the wheel.
