Windows 7, BootCamp and Trackpad Scrolling

A lot of people seem to be having issues with the trackpad driver when running Windows 7 on a Macbook Pro using BootCamp. My experience is that if you use the BootCamp 2.1 drivers the touchpad works pretty well - 2 finger scrolling, 2 finger right click - all that works great. The only issue is that 2 finger scrolling is way to fast.

What a lot of people dont seem to realise is that once the trackpad driver is setup, you can use the standard mouse control panel to change the properties of the 2 finger scrolling. It seems that the driver is incredibly basic - simply generating linear scroll-wheel events when 2 fingers are dragged up or down. By default, Windows scrolls 3 lines for each mouse-wheel 'click'. Since the 2 finger scrolling generates quite a lot of scroll-wheel events, i recommend reducing this to 1 line for each 'click'. You can do this by pressing the windows key, typing mouse and pressing enter to go into the mouse control panel. On the Scroll tab you can change the setting under the Vertical Scrolling section.

The result is a nice experience overall - a very smooth scrolling action when using 2 fingers. If you need to move more quickly up and down, page-up/page-down (Fn+Up/Down) will do that.
