Prevent adding, dragging, dropping and closing the Taskbar's toolbars

Description

Prevents users from manipulating desktop toolbars. If you enable this setting, users cannot add or remove toolbars from the desktop. Also, users cannot drag toolbars on to or off of docked toolbars. Note: If users have added or removed toolbars, this setting prevents them from restoring the default configuration. Tip: To view the toolbars that can be added to the desktop, right-click a docked toolbar (such as the taskbar beside the Start button), and point to "Toolbars." Also, see the "Prohibit adjusting desktop toolbars" setting.
