I'm on the soapbox this morning, after a careless visit to Microsoft Update that netted me numerous updates that I neither expected nor wanted.
First of all, if you're not aware of this, the U.S. has changed the rules for Daylight Savings Time to begin sooner and end later. However, I am in Arizona and we don't observe DST; Windows knows my time zone, but still installed that particular update.
Next, I found a "Euro update for Slovenia" which likewise doesn't belong on a US system - especially not an automatic update that gets pushed out to everybody.
Then came numerous updates for MS Office 2003-2007 and/or SharePoint 2007 interoperability, about which I could care less.
End of rant.
