Sorry for belated reply, and renewed thanks for your abiding help and patience
with an old-age pensioner.
I turn 80 next June, i.e. if I survive heart and cancer operations.

I have given up on automatic opening of Windows 10 as somewhere (I forget where, my memory playing tricks with me!) I was told that this impossible with Windows 10. Anyway, I am getting used to entering my PIN number to access Windows.

Have decided to forget about changing my password, but have kept a copy of your tips for reference, in case of need.

Kind regards.

Joe
