I got one last night advising me to download a service pack for my Office 2007.
Since I'm on Office 2003, my reaction was the same as yours.
The answer is obvious now: you got mine, I got yours.
I turned OFF all those automatic updates a long time ago. That's avoided a lot of pain since. I rely on ZoneAlarm and the virus protection stuff to look after me.
I spent this morning "fixing" the computer of an old parishioner that had locked up because of a Windows update. Several bits didn't work any more, and hadn't for a while. Now all sorted, updates turned off, and she's happy. Shields Up! gave her machine a full "pass".
