This isn't a great example (or maybe it is considering how non-trivial the operation is), but running stuff from the command line can often be great for tech support. There is a reason support normally asks people to open things from the run dialog instead of asking them to go through the start menu. This might be a bit too much to expect grandma to perfectly type, but "sudo apt-get update" and "sudo apt-get upgrade" to update her system is certainly easier then trying to describe what to click on a graphical UI.
