You can't break the computers as such but if you work with enterprise software you sure can run the wrong process at the wrong time, or with the wrong options and make a mess in the database. Sometimes that commits IT people to spending hours or days cleaning up. Lots of people still spend all day on these old school systems.

Because lots of apps are linked up (emails can be filed so Document management, which integrates with CMS....) users don't know where the boundaries are. So it's a small wonder that they get scared of the system. And I think that fear reinforces any uncertainty with computers in general.

Yup. As you gain more experienced with computers, you understand what will and what won't break a computer. The same thing goes for an OS.

I bet there are a number of Windows users that never update, in fear that it will break something. (To be fair, it might, but usually it's unlikely).
