Critical Windows Update Causing Problems

One of the updates that Microsoft sent out on Tuesday, the MS07-040: Vulnerabilities in the .NET Framework could allow remote code execution, has issues. There are already 6 kb articles discussing problems caused by this update, from the SANS Internet Storm Center,

The reports we got so far seem not to lead to any specific thing that happens in many cases, just various things going haywire. We really do appreciate the heads-up warnings we get from our readers as it allows to write little warnings like this one.

We’d like to offer a double advise at this time:

If you run into trouble do call Microsoft and open a case, it’s the only way to get attention to the problem from those who know best how to fix it. It should be free. In the US: call 1-866-PCSAFETY, check their website for other countries, support with patches should always be free.
Do read through for your specific combination of .NET framework version and you specific OS the relevant KB, some of them were prepared in anticipation of certain problems. They are all linked from KB 931212. Source: MS07-040: .NET update trouble

So, if you have been having trouble since you updated, it could be causing you some problems, here are the kb articles that have been released, so far, concerning this update.
