Thanks guys for the input. All good info. Maybe I'm not going crazy after all. I hope. I haven't had any problems with Windows 10...
that I'm aware of. 
However, there seems to be no intuitive ...that would lead you from Vista to Windows 10. It's ALL hunt and peck..click on some icon to see what it is...and hope you aren't doing something you don't want to do. Everything is hidden behind something else...
I clicked "something".. while I was typing my first response to your posts..and Bada Bing...everything went away.
NB
