Second part is about explorer itself. While it might seem like a common utility (even necessary), I find it very rare for a general user to know about it (my wife does not, nor my parents, siblings, their friends,...but my wife's father does). Once they see it, they have no idea what to do. Seconding. Especially before Windows 7 added Explorer as a pinned item by default, the less-technologically-literate persons I know would simply called it "My Computer", and used it in the large-icon, single-paned view. On one occasion while helping a friend find a file, I opened Explorer and switched it to the Details view option. Between that and the folder hierarchy in the left pane, I guess it looked different enough from "My Computer" that my friend was used to and I was given the reaction "Wow, you're really in the guts of the machine, now."
