It's not trivial, you're right -- which is why you put your A-level people on it. Windows Update is Windows now... yet every week it seems they push another broken, malformed, or generally customer-unfriendly update. Their new policy of suppressing release notes is just (brown) icing on the cake.

The end result of all this stupidity is to incentivize users to turn off automatic updates. Everybody with an Internet connection will suffer for that.
