3.5. Removing System Menus for All Users
To remove the System Settings submenu of the Applications menu, edit
/etc/xdg/menus/applications.menu, by adding the following before the final </Menu> tag
in the file:
...
<Menu>
<Name>System Settings</Name>
<Deleted/>
</Menu>
</Menu> <!-- End Applications -->
The other submenus of the Applications can be removed in similar fashion. Note that the name of the
submenus can be determined from the files located in the /usr/share/desktop-directories/
directory.
