They have now, if you know where to go. Certainly nothing in their own Forums where thousands of people are going to try and solve the problem!
It may be obvious to IT people to check KB pages, not so for the ordinary person. They end up in such forums, where there is nothing from MS whatsoever. This is one of their biggest weaknesses. Other companies would have published on social media (facebook, twitter,...), in forums, blogs, etc... to try and reach the largest audience possible to notify and reassure their clients. MS has chosen quite differently and I for one think it is a very bad decision on their behalf. This is exactly the type of thing that drives people to look at alternatives (Mac, Linux, Google, ...)
One way or another, at this point it is a sit and wait situation.
