I have two ISO for Windows 10 x64 10586.. First one is obtained after the Insider Build 10586 came Second one is obtained as ISO download from Microsoft tech branch.. Although both seems to be TH2 release but there is a slight difference in version info.. First one shows 10586.3 Second one shows 10586.0 Whats the difference ?? Visually and feature wise, as daily driver, I didn't notice any difference between them yet but .0 seems little faster and smooth compare to .3 built.. Can anyone shade some light on this.. Thanks..
