Today's the day. Microsoft is making available to anyone and everyone with Windows 8 and Windows RT a public preview build of its next Windows release, Windows 8.1, codenamed "Blue."
On June 26, Microsoft is making the Windows 8.1 preview available for download via the Windows Store. If you choose to download the preview, make sure you know that you will have to reinstall your apps before you move from the preview build to the release-to-manufacturing (RTM) bits.

Most if not all of the new features in Windows 8.1 have leaked and or been detailed by Microsoft to date. The biggest one in many Microsoft watchers' and customers' eyes is the return of a Start Button of sorts. While this isn't a Start Button with a Start Menu like the current Windows Start buttons, it will provide an anchor for those who have had trouble navigating Windows 8.
Boot straight to desktop is a built-in feature of Windows 8.1, as we've known for a while now. And the search experience in Windows 8.1 is getting a major overhaul.
