I have moved several folks onto win10 who initially had to be dragged kicking and screaming from win7...
1) I delete *ALL* the Microsoft 'apps' crud thats pinned to the start menu, and pin their favorite stuff there instead
2) I disable Cortana via a regedit hack
3) I setup Chrome (or Firefox, whihcever is their preferred browser) as the default, I also install MPC-HD as the default media player
3) I set them up with a local account (which yes, MS is hiding deeper each time)
and blam, in about 5 minutes they are perfectly happy, in a day they are amazed at how much faster it is. in a week they comment that it hasn't crashed once.
