I dont know where you have been, but it is far from worth updating. It dosent install or reboot behind the scenes, but it will keep popping up with a notification for SP2 unless you shut off the automatic reminders.
It is definetely not worth updating to Service Pack 2. Have you even upgraded to service pack 2? It sucks. If you do it from a clean install, it tends to work better. If you just do an upgrade, your computer tends to die. I upgraded to it at one point, nearly hosed my entire computer. Many problems, but they all seemed to mysteriously vanish once I removed SP2. There was also, at one point, a entire list of programs that would not work with SP2, available at microsofts' website. I worked on a help desk at a law school, and we had to post signs everywhere that said we do not support SP2, because of the massive compatinility issues we had with it.
In short, it is not a worth while update. And stop being so condascending.
