I am regularly switching between OSX and Window7 and I kind of got used to the new scrolling direction introduced with OSX 10.7 (Lion).

Therefore I thought it would be nice to have this scrolling consistent across both platforms.

Looking for a way to reverse the scrolling direction on Window 7 I found this solution on superuser.com (http://superuser.com/questions/310681/inverting-direction-of-mouse-scroll-wheel):

  1. Find the hardware ID of the mouse

    • Go to the mouse control panel
    • Select “Hardware” tab
    • Click “Properties” button
    • Select “Details” tab
    • From the drop-down list choose “Hardware IDs”
    • Save the VID*** entry ( e.g. VID_045E&PID_0039 )

  2. Find and change the corresponding configuration settings in the registry

    • Run regedit.exe
    • Open Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID
    • Here you should find an entry for the hardware ID of your mouse
    • In all sub-keys of the hardware id key look for the “DeviceParameters” key and change the “FlipFlopWheel” value from 0 to 1

  3. Make it work

    • Unplug the mouse
    • Count to five :-)
    • Plug the mouse back in
