Microsoft is giving people a peek into Windows 8.1, a free update that promises to address some of the gripes people have with the latest version of the company's flagship operating system.
Although the preview version of Windows 8.1 is meant for Microsoft's partners and other technology developers, anyone will be able to download it for free starting Wednesday, exactly eight months since desktops, laptops and tablets with Windows 8 went on sale. The version of the Windows 8.1 update meant for the general public will come out later in the year, though a specific date hasn't been announced.
Many of the new features have been shown off already. A three-day Build conference, which starts Wednesday in San Francisco, will give Microsoft developers a chance to learn more about the new system and try it out. It also will give the company a chance to explain some of the reasoning behind the update and sell developers on Microsoft's ambitions to regain relevance lost to Apple's iPad and various devices running Google's Android software.
There's also speculation that Microsoft could show off a new, smaller version of its Surface tablet computers. One of the new features in Windows 8.1 is the ability to work well on smaller-screen devices.
Windows 8, which was released Oct. 26, was meant to be Microsoft's answer to changing customer behaviors and the rise of tablet computers. The operating system emphasizes touch controls over the mouse and the keyboard, which had been the main way people have interacted with their personal computers since the 1980s.
But some people have been put off by the radical makeover.
Although Microsoft has said it has sold more than 100 million Windows 8 licenses so far, some analysts have blamed the lackluster response to the operating system for a steep drop in PC sales in the first three months of the year, the worst drop since tracking by outside research firms began in 1994.
Among the complaints: the lack of a Start button on the lower left corner of the screen. In previous versions of Windows, that button gave people quick access to programs, settings and other tasks.
