I know that everyone complains about Microsoft, and I've certainly done my share of Redmond-bashing, but I have to say that their automatic updates do a pretty darn good job. They can get awfully annoying, and from time to time there is one that goes awry, but overall they offer a well-integrated experience that runs smoothly and I give them a thumbs-up.
Compare that to other companies like Dell and you might just see what I mean. You have to go to their site, download them individually, unpack them individually, try to find where they unpacked to (assuming you didn't make a note of all of them), watch as they may or may not overwrite each other. It's horrible.
