I talk to a lot of users who are not utterly incompetent with computers but really don't want to focus on them any more than they have to. Almost all of them have enabled this kind of thing without understanding it at all because microsoft pops up nags for this kind of thing constantly and specifically designs them so that the easiest way to get them out of the way is to enable whatever thing they want you to enable (at which point, they will never mention it again, precisely the opposite, I would suggest, that you should do when you have fundamentally changed how the user's files are stored, and in stark contrast to if you refuse, which will result in you being nagged again and again).
