I mistakenly mentioned "roll back", which caused the focus to sit on that topic for a while. Though, it is probably a good thing as rolling back is the solution many want to reach for. If not that, manually installing a driver found somewhere.

My main concern is how to remotely (or at least without local administrative rights) diagnose vague and intermittent hardware problems. And, yes, we have a growing collection of vague and intermittent hardware problems.
