If you need to disable the option "right clicking the menus for mapping a drive" you can use the GPO below. User>Policies>AdministrativeTemplates>WindowsComponents>FileExplorer>Remove "MapNetworkDrive" and Disconnect NetworkDrive. Just Enabling will do the work.
If you need to remove all mapped network drives User>Preferences>Windows Settings>Drive Maps
If you need to create a shortcut for homefolders for each user on the desktop, use the GPO below.
