Windows 8.1, codenamed "Blue," is introducing a number of changes designed to make the new operating system more palatable to current Windows users. Windows 8.1 is adding a Start Button, a boot-straight-to-desktop option; the ability to unpin all Metro apps; built-in tutorials; an improved Windows Store and a host of other consumer- and business-focused features. Microsoft launched its one and only Windows 8.1 consumer preview test build in late June.
Microsoft may have opted against announcing Windows 8.1's RTM on Friday so that the news wouldn't be overshadowed by the announcement that CEO Steve Ballmer is retiring some time within the next 12 months. As I blogged previously, my sources said Microsoft was targeting Monday August 26 as the day it would RTM Windows 8.1.
Of course, it needs to look like a big secret so I won't say any more."
