It would probably be noted products were not using Final optimized software etc Even the Pen had new Drivers updated just today But looking at other hands-on reviews online, this is definitely replacing my aging laptop, I preordered the 256GB model

I've updated an older Lenovo L420.. Windows 7 to 8.0 to 8.1 to now 8.1 Update 1, I've had ZERO issues. as well I've updated my Dell Venue 8 Pro from 8.1 to Update 1, ZERO issues, updated my mums system as well so that leads me to believe its more an issue with conflicting OEM software/settings

If some users can't update it sounds like an OEM issue to me, or other conflicting software/ driver or firmware problem.. Not much Microsoft can do, its an OEM problem

Most Windows users have automatic updates enabled, they will get Update 1 automagically, without even thinking. I mean, Surprise Surprise, if you don't keep your OS current with updates, no newer updates can be applied... This is not breaking news, it just makes sense Also Windows 8x support isn't ENDING, you must apply OS updates to continue receiving support
