Check your facts. This was everywhere. Microsoft mistakenly released a TEST update to live Windows Update servers. Some people installed it and it caused issues.

From your own articles:
"As it turns out, the “patch” was totally harmless, although it certainly caused some angst among the small group of users that posted to the support thread, who wondered if the Windows Update service was itself compromised. Fortunately, it wasn’t."
"The patch is thought to have been pushed through consumer machines running Windows 7. Enterprise users running Windows Server Update Services (WSUS) don't seem to be affected."
So you're wrong on all accounts except that an update was pushed through accidentally.
The update had NO affect on anyone's computer (except ONE person who both articles have quoted...couldn't even do a system restore? More likely something the user has done to screw up his system, not a 4.3MB test update. Had the update actually affected core Windows files to the level of screwing up the entire system such that a system restore wouldn't even work this consequence would be much more widespread than one user).
You're also wrong when you stated even WSUS users got pushed the patch. Not what your articles said.
If you're going to try and prove people wrong by pasting articles, at least make sure you read the article and make sure it doesn't prove YOU wrong first.
