I downloaded Win10 when free. Minimal use of old XP Gateway laptop: news, some email composing, some shopping, card game. Really not much use.
Turned on today and all was different: most of icons gone in task bar (at bottom), window icon and circle (Cortana) there open only with right click to not usual list, settings opens to blank window. Nothing is as it was when turned off night before.
I don't know enough to know what to do. Have looked at reloading Win10 but says all files would be erased. I'm willing to try anything but don't know where to start.
Hope someone can give me suggestions.
