James........I've had pretty good luck installing Classic Shell (as Andy said) on the computers of friends and family who don't like Win 10. When you run it, it will ask you to choose what older OS you want it to look and act like. Read the choices thoroughly, and you will be able to get pretty close to what you want.
One thing. Sometimes when Win 10 does updates, it resets your system to look like the Win 10 you're seeing now. So you would have to rerun Classic Shell. It's only happened once to my Mom's computer, but it's an easy fix.
For those of us trying to bite the bullet and learn Win 10, one thing that helps a lot is that you can RIGHT click on the start button, and a menu will appear from which you can run Control Panel, Device Manager, Command Prompt, Network Connections, and a few other things.
As far as why things can't stay the same, I ask myself that question every time I accidentally look in the mirror. But doing so has broken almost all of mine, so relief is in sight.
