On Wednesday February 29 IT Giant Microsoft has come forward with the test version of Windows 8 operating system, which is framed to run without any interruptions on computers and in fastly-growing tablets.

Windows president Steven Sinofsky said that "Windows 8 is a generational change in the Windows operating system,"

"It's Windows reimagined," he added, on the sidelines of the world's biggest mobile fair in Barcelona.

That Microsoft had picked the Mobile World Congress to hold its consumer launch was not coincidental, as the operating system is meant to be its answer to Google's Android platform and Apple, which has dominated a market it ignited with the release of the iPad.

Like its two competitors, Microsoft is going big on the app concept.

Unlike previous generations of Windows, which has a taskbar pulling up a list of software, the latest version is applications-based, with a selection of apps tiled on the startpage.

And the gestures controlling how one selects or moves apps around are those currently common on smartphones -- swipes or taps on screens.

Steven Sinofsky said " Operating systems gets new life with Applications.The experience gets better with more Apps.
