Beside the crappy, missing, or useless progress bars, my current beef are the "descriptions" of Windows updates, which never tell me what the updates are actually updating. Sure, they give you a cryptic number that you can google, but a simple one sentence description beside the generic text they use sure would be nice. I usually do only the "important" updates, but recently I decided to check out the "optional" ones. There were a bunch of "security" updates in there. Why the heck were they tucked into "optional"? How is the status of an update decided? My theory is that a whole bunch of developers working simply don't care, or are so overworked that they cannot care, about the descriptions. The updates are, in fact, truly designated, but the people finishing them simply copy'n'paste standard names and descriptions. If my theory is true, neither of the two options are really trust inspiring for a major company supplying security relevant and mission critical products.
