The registry entry, HKCU/Control Panel/Desktop/WheelScrollLines is not enforced when I reboot my machine. Using the Mouse Properties Dialog, I am able to change the value in this entry to one of my liking. According to what I have observed, -1 causes full page scrolling, 0 disables scrolling completely, and 1 or higher specifies the number of line scrolled with each notch of the wheel. Regardless of what value I have chosen, on reboot the value is set to 1 in the Mouse Properties dialog. However, the value in the registry is still set to the desired value. The registry seems to be updated correctly when I use the Mouse Properties dialog. Anyone know why this value would not be loaded when windows starts

I found a fix for this problem. Like many laptops, mine is equiped with a synaptic's touchpad. The touchpad driver override the wheel settings for all mouse devices. Why? I have no idea. There isn't a wheel anywhere on my laptop. If you are experiencing this problem add the following DWORD key to you registry
HKLM/SOFTWARE/Synaptics/SynTPenh/AllowScrollSettings DWORD value of
After reboot, your mouse wheel settings will no longer be reset.
