I just performed an upgrade from 9.0 to 9.5. All went pretty well except once the update was finished, random Windows desktop devices were rebooting without warning. Luckily, we didn't have anyone complaining that they lost data or that it occurred mid presentation. I can see this turning into a pretty big gotcha if it happens to the wrong person at the wrong time.
