Wheel Scroll Lines not loaded on Reboot

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 1
After reboot, your mouse wheel settings will no longer be reset.

New to this forum. Do I dare ask a question in a thread that is over a
year old? Here goes nothing:

You wrote to go to
"HKLM/SOFTWARE/Synaptics/SynTPenh/AllowScrollSettings and make a DWORD
value of 1.
I know that in many cases there are only 2 choices '1' and '0' and they
have special meaning. Does it in this case? or is '1' meant to mean one
scroll line? Since I want to change my default to 5 scroll lines can I
change it to 5 instead? I did '1' and it did nothing to my mouse scroll
settings, whose default seems to always be the number one regardless of
what I tried.
To be more precise to me "HKLM is the main folder and
/SOFTWARE/Synaptics/SynTPenh are its subfolders. and in SynTPenh I went
to the right pane and created the Dword 'AllowScrollSettings' and set
it's value at one.

I spent a lot of time trying all different options and none of the solution work. Finally, I went to synaptics site to download a new driver and magic, it fixed the resetting problem :)
