WU is updating it's own WU files
exactly. I see no harm in this at all. My copies are genuine.
went through hell after WGA flagged it as a pirate copy
I've seen this also, hence my response in the original post which Philly made reference too in this one..
on a few models of computers, when SP2 is installed, the video drivers go south. It's not a big deal on a single computer, but can you imagine the nightmare if you came in to find 500-1000 computers with fried video drivers because of stealth updates?
SP2 is not a "stealth" update. One must choose to install it, unless of course you have WU set to auto install criticals. I shudder to think that a business with 500-1000 computers would do this.
A large network, if the network admin has any competency, will have an alternate method of patch management that would stop this "stealth update" process. As the articles mention, WSUS and SUS did not roll out this update.
Bottom line is: "If you have a genuine copy of Windows, what have you got to fear?"
Pretty much sums it up..
