Most people cant actually use Windows. What they can use (barely) is a couple applications and utilities. Put them in Linux and they still won't be able to use the system, they'll still get by with a few applications and utilities which will use the exact same paradigms. So no big difference.

Also they won't dump data in random places on the disk but only in the user's home. Which is an improvement.

And for the few that want to understand something, unlike Windows a lot of the help is built-in. The error messages make sense. There's a logic to things. All in all, Linux is easier.
