(AP) Microsoft is using a three-day conference this week to give 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. A preview version of Windows 8.1 was released Wednesday at the start of the Build conference for Microsoft partners and other technology developers.
Although many of the new features have been shown off already, the conference offers 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.
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. Research firm IDC blamed Windows 8 for accelerating a decline in PC shipments worldwide.
Microsoft's event is taking place at The Moscone Center in San Francisco. The keynote kicked off shortly after 9 a.m. PDT.
Here's a running account of the event, presented in reverse chronological order. All times are PDT. Presenters include CEO Steve Ballmer.
One of the shortcomings of Windows tablets is a lack of apps for them. Ballmer says that's changing. He says Facebook, for instance, is now making an app for Windows 8. There are also fantasy football apps coming from the NFL.
The crowd cheered as Ballmer mentions some of the previously announced features coming to Windows 8.1.
That includes the ability to have machines automatically start up in the older, desktop mode rather than a tablet-style, full-page start screen that Microsoft has been pushing with Windows 8. Windows 8.1 will also restore a Start button on the lower left corner of the screen, although it will work differently in bringing people to the full-page start screen rather than the Start menu found in previous versions of Windows. He also talks about new search functions, using Microsoft's Bing search technology.
Ballmer announces new phones from Nokia running a phone version of Windows software.
He also talks about a smaller Windows tablet than the ones previously available with Windows 8. The new Acer Iconia has a screen that measures 8.1 inches diagonally. He says Microsoft and its partners had to do a lot of work to "bring the small tablet form factor to life." Ballmer says customers should expect many smaller Windows tablets to come. That will allow Windows to compete with popular small tablets such as Apple's iPad Mini and Google's Nexus 7.
Ballmer appears on stage to welcome 6,000 people at the conference and an estimated 60,000 watching live on a webcast. The audience includes hardware vendors and software developers.
Ballmer warns that Microsoft won't be talking much about the Xbox, Skype and Office 365, as there have been recent announcements on those. Rather, he's there to talk about Windows and related services. He says the announcements he has planned underscore Microsoft's transformation to "an absolutely rapid-release cycle."
