My screen went blank, said it was Restarting and doing something or other - I thought it was Up-Dating in rather a peremptory manner. And it took forever, to the point that I went back to bed. When I got up, my laptop brought me to a world reminiscent of Windows 8. I can't use my laptop at all.
I use (or try to use) Google Chrome.
If there's anything that would make this system functional, or remove it, I'd be very grateful if you'd tell me.
(see how calm I am?)
