They can't even update their own Knowledge Base
I had 2 cumulative updates yesterday with the vague 'they fix stuff' as the description and to look up more details on the Knowledge Base. After some futile searching, I decided to try talking to the Microsoft Answers chap. His advice was to 'Search BING' and click on one of the results. I did as he suggested and it was basically an article on how Microsoft haven't posted any information on the updates. I think he was a bit red-faced on the other end.
