Winodws Update sure didn't forcibly install SP2 on my machine the last time I updated a few security patches... which was yesterday. oh my bad then, I heard that in the spring. I guess it was a rumor, but I have a legit windows and I already had sp2 for a long time anyway Eh, I've heard the exact same rumor. I was quite surprised to find that it WU didn't install SP2 automatically, rather, it asked me about it.
