There is no reason that you should not use parental controls. I was trying to show you the various methods available, since I do not know of a way to change the start menu, other than the way that is shown in the above link. If others come by they may have suggestions that will more fully accomodate your needs. If no one else comes by, you have the various methods, that I know of, that can resolve your problem. I agree the easiest appears to be the use of Parental Controls.
