Microsoft started its Build developer conference on Wednesday, and kicked the event off with the release of Windows 8.1 Preview, a sneak-peek version of the next version of Windows 8. As far as we can tell, Windows 8.1 represents a commitment to the failed mobile paradigms introduced with Windows 8, an OS that chiefly saddles tablets with Microsoft's desktop legacy of yore. A blog post from Brandon LeBlanc, a Communications Manager at Microsoft, talks about the release, including the really huge news that it includes the return of the Start button to Windows. Hoorah! Happy days are here again! Oh, and for some entertainment, note that the comments on the blog post are filled with people complaining about problems installing the preview or asking for help. The video below offers a semi-tour of the new release.
