After setting the mouse pointers the way you wanted, you would need to save your Windows theme afterwards to lock them in. Steps 8 and 9 in the tutorial below will have more details on this to help better.
i get a similar problem with my mouse scrolling. in pointer options of the mouse where you click "enhance pointer precision," every time i start my computer it unchecks that box, even though i recheck it every time. can i just save the theme and that will solve the problem? thanks.
