A few things happened. I am now able to start the computer in Safe Mode with Command prompt. Ver slow but it gets there after an hour or two.
I also managed to give commands for Devise Manager and Control Panel.
I don't know what I did, playing around, but at one stage all my Desktop icons appeared and even the bottom line where the Start button is. With the Start button I could among other things open Explorer and the Run box.
Un fortunately I cannot replicate it past the Control Panel. Is there a dos command to refresh the Desktop?
