I think we have differing terminology. I would consider this a GUI. After all, the command prompts are running in windows. You can move them with your mouse. Other utilities (like regedit) are available, and are not command line / text-only applications.

‘Windows’ would be an interesting name for a product that by default had none.

Ok. Can you post an image of what the screen looks like after you log in?
