Pluggable USB-VGA-165 USB 2.0 VGA Adapter not working on Dell Inspiron 15” 3521 (Windows 10 Upgrade).

The Pluggable USB-VGA-165 USB 2.0 VGA Adapter not working on Dell Inspiron 15” 3521 (Windows 10 Upgrade). It shows only my desktop on the projector but no applications like PowerPoint are displayed, it just keeps showing the desktop.

I was initially hopeful that the adapter had solved my problems, not being able to project anything since the upgrade to Windows 10 (I can only assume that Dell and Microsoft did not work together to ensure the graphic drivers on this PC would be supported)!
