This is a problem. Microsoft did not RTM Update 1 with any sort of timeframe of past updates. It never went to OEMs (I'm using this term to include System Builders) first but went to MSDN/Technet. This meant that OEMs got the update pretty much at the time of GA and everyone else. Rather than the typical RTM period of 2-3 months of testing, it was less than 1 week. Now this news article comes out and says that 1 month from then, any PC not running 8.1 Update 1 cannot get updates? This could* be a support nightmare! What were they thinking?
