How to bring OSX Lion's Natural Scrolling to Windows 7

If, like me, you move between Windows and Mac on a daily basis you may have found yourself finding it a little hard to figure out which way to scroll the mouse.  With OS-X Lion Apple introduced ‘natural’ scrolling which means that when you scroll the wheel on the mouse an upwards push sends the scroll bar down, that might sound weird but in essence your upward movement of the wheel actually pushes the screen upwards – very much like a touch gesture on a smartphone or tablet. Whether you love it out loath it, getting used to switching between the two is difficult and you could either turn it off on the Mac or if you like it you could bring the same feature to Windows.  As it happens the feature is already there, to enable it you need to edit a registry key and if you’re not familiar with this process I would advise caution since a mistake in the Registry can make your machine quite unstable but if you’re comfortable with RegEdit you’ll need to modify the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\????\????\Device Parameters\FlipFlopWheel

Set the value from 0 (default) to 1 where the ????\???? section are whatever device IDs you can see.  I changed the FlipFlopWheel property for all of the devices I could see, unplugged and re-plugged the mouse and the then it worked – natural scrolling on Windows.
