I guess for example that the http://support.microsoft.com/kb/3004394 http://support.microsoft.com/kb/3004394 Win7 fiasco comes from the update being only tested on machines with test roots installed, right? And Win8.0/Server2012 seems to be treated as second class with more than one bug affecting only that one, which reminds me of the odd support lifecycle where the server edition was treated as an older release but the client edition get treated as a older service pack.
