I recently started using a Mac.  One of my favorite features is the way the mouse wheel scrolls.

Normally, when you scroll down, the lower part of the screen moves up and becomes visible.  With then new OS-X, when you scroll down, you move the screen down and visa versa.

In order to make your Windows mouse wheel behave this way, do the following:

  • Open the control panel and select Mouse
  • Click on the Hardware tab select your mouse.
  • Click Properties.
  • Go t the Details tab and select the Hardware ID property from the dropdown.Now run regedit.exe
  • Find the Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID
  • Under this Key find a subkey with the Hardware ID you found earlier.
  • Expand this key and subkeys to find Device Parameters.
  • Change the DWORD FlipFlopWheel value to 1
  • Copy the VID…..etc id of your mouse.
  • Now run regedit.exe
  • Find the Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID
  • Under this Key find a sub key with the Hardware ID you found earlier.
  • Expand this key and subkeys to find Device Parameters.
  • Change the DWORD FlipFlopWheel value to 1

Disconnect your mouse for a few seconds and plug it back in (for a wireless mouse disconnect the USB device).   Your mouse wheel action should now be reversed.

To put the mouse wheel back as it was do the same thing and change FllipFlopWheel to 0.
