How to make mouse wheel scroll setting stick (Windows XP)

Question

On XP, in TweakUI I set the mouse wheel to scroll by 1 line rather than the default 3. When I reboot it's always set back to 3. It's a laptop with a generic Dell mouse and I can't see any specific mouse service running in Process Explorer. It happens when docked or undocked. Any ideas how to make the setting stick?

I had this problem with my HP labtop, try to install driver from Dell.
