MS-DEFCON 2:
Patch reliability is unclear. Unless you have an immediate, pressing need to install a specific patch, don't do it.
I learned about this site from Bob.
But here are some caveats that Woody also mentions:
My usual boilerplate advice:
For those of you who are new to this game, keep in mind that… You should always use Windows Update to install patches; downloading and installing individual patches is a clear sign of impending insanity. I always install Windows Defender/Microsoft Security Essentials updates as soon as they’re available – same with spam filter updates. I never install drivers from Windows Update (in the rare case where I can actually see a problem with a driver, I go to the manufacturer’s web site and download it from the original source). I almost never install “Recommended” patches (reader Marty suggests that you uncheck the Windows Update box that says “Give me the recommended updates the same way I receive important updates”). If Windows Update has a patch but the box isn’t checked, DON’T CHECK THE BOX. It’s like spitting in the wind. I use Chrome and Firefox, and only pull out IE when I feel very inclined — but even if you don’t use IE, you need to keep up with its patches.

Bob, I don't see Windows Malicious Software Removal Tool Kit listed in the boilerplate advice: It should also be ignored for now?
