This article discusses editing the Windows Registry. This gives you complete control over the configuration of your menus, but you should be extremely careful not to change Registry values that are used by other applications. The author accepts no responsibility for any problems that may arise as a result of any changes to the Registry, even for those changes outlined in this example.*
