hi there! just registered to tell you what i have experienced after visiting the windowsupdate.com site on
wednesday 02:45a.m. cest
i installed all updates and checked "reboot later"... after 10min. or so i left my room for a while.
when i came back i saw xp rebooting and was really pissed off (some data was still open and not saved...)

checking my eventlog after this was kind of scary:
