If you enable this policy setting, Search, Share, Start, Devices, and Settings will no longer appear when the mouse is pointing to the upper-right corner. They'll still be available if the mouse is pointing to the lower-right corner. If you disable or don't configure this policy setting, Search, Share, Start, Devices, and Settings will be available by default, and the user can configure this setting.
