A few words of thanks would be greatly appreciated.

Windows - Command Prompt in full screen mode with the mouse cursor

If you need a command prompt in full screen, here's how:

Open the command prompt, and maximize the window (it is still not full screen).
Right click on the top of the window
Edit/ Properties .
In the Window Preview.
Instead of 8 x 12, select 16 x 12
In this way, the command prompt is full screen and the cursor will be displayed.

Note: do not select "Full Screen" in Properties> options> display options as the command prompt will be full screen but without the pointer.
