Windows 9 on the way, Big challenge for Satya Nadella to get Microsoft back on track

Now, Windows 9 by Microsoft

Windows 8 by Microsoft does'nt satisfy many users, becomes reason of Steve Ballmer's resignation. Windows 8 saves Microsoft only mobile,  Windows Phone remains mired with around a 4% market share in the U.S. and under 1% market share in China -- the two largest smartphone markets in the world.

It couldn't have come at a worse time, just when desktop and laptop sales have been shrinking, and tablets and smartphones taking off. Rather than stave off the decline of traditional PCs, Windows 8 helped increase it. And it did nothing to help Microsoft in mobile.

That's why there's so much riding on Windows 9, expected to be released in the middle of 2015, although at least one rumor has it arriving in October of this year.

Windows 9 will likely be the last chance for Microsoft to get on track, Big challenge for Satya Nadella, new CEO of Microsoft.

Even though development of Windows 9 is well under way, for better or worse Nadella will be judged by it. If it's a great operating system, he'll cement his power at Microsoft for years to come. But if it falters, he might not be able to survive long after it.
