intend to keep OFF the internet--just as backup storage and to use some software that won't work on Win10.
I have to say that I really hated WIN10 when it came out. It was so unlike win 7 and all the predecessors, but it has grown on me. The only thing that really gets me is how bloated it has become. Every time it updates (as well as my other major software, especially security packages), I hold my breath for no conflicts. Mostly things go smoothly. In November, that was not the case and it took me four full days to get things working again. I came close to ending up with a bricked laptop. I'm no Luddite and I'm fully able to troubleshoot most issues, but that episode left me reeling. (It was a full security package update that set off the problems, btw and I have since removed it totally and gone with a competitor).
The one thing EVERYONE should learn to do (besides backing up their major files) is to create SETPOINTS at least once a week and before letting Windows do updates. Just in case.
Honestly, if I was scared of technology and/or unwilling to spend the time learning what to do when things go wrong, I think I'd try to establish some kind of tech support contract with a trusted person or group that specializes in that. Just make damned sure you can trust them if you keep secured info on your computers.
Learning at any age keeps you young. Maybe the best advice is to seek some classes or focused training to help build self-confidence in dealing with the problems as they come up.
