Microsoft CEO Steve Ballmer gave a presentation at the launch of Microsoft Windows 8 in October 2012. But because of user concerns, Microsoft already is preparing to launch Windows 8.1 later this year.


Twitter to invest 'heavily' in TV, add video content

Twitter Chief Executive Officer Dick Costolo said he sees television companies as valuable partners for its microblogging service and is investing accordingly.

"Twitter is the social soundtrack for TV," Costolo said. "We've decided to invest heavily in that."

Twitter is adding video content to bolster ad revenue in a bid to reach $1 billion in sales by 2014. In May, Twitter announced a partnership with the National Basketball Association to stream game highlights, as well as a deal with ESPN, a Walt Disney unit, to show snippets from soccer matches, college football and other sports.

The microblogging site is also investing "quite a bit of money" in improving security. Last week it added two-step authentication, which requires users to input a code sent by text message to a mobile phone to log in.

Windows 8.1 to fix Windows 8's mistakes

Microsoft is trying to fix what it got wrong with its radical makeover of Windows. It's making the operating system easier to navigate and enabling users to set up the software so it starts in a more familiar format designed for personal computers.

The revisions to Windows 8 will be released later this year. The free update, called Windows 8.1, represents Microsoft's concessions to longtime customers taken aback by the dramatic changes to an operating system that had become a staple in households and offices around the world during the past 20 years. Research group IDC has blamed Windows 8 for accelerating a decline in PC sales.

With the release of Windows 8 seven months ago, Microsoft introduced a startup screen displaying applications in a mosaic of interactive tiles instead of static icons. The shift agitated many users who wanted the option to launch the operating system in a mode that resembled the old setup. That choice will be provided in Windows 8.1.
