It may seem odd that Microsoft executives are traveling all the way to Barcelona, Spain, to debut the beta version of the upcoming Windows 8 operating system at a mobile device show.

But Microsoft, which has launched drugs and mobile phones lengthy prior to competitors simplest to see others dominate the ones businesses, is hoping that the following version of its pc working device will reverse years of stumbling.

“It’s an acknowledgement that mobile is what Microsoft needs to address,” said Rick Sherlund, an analyst with Nomura Securities.

Tomorrow, the software giant will debut the Windows 8 beta, something the company is calling the Consumer Preview, at the Mobile World Congress trade show in Barcelona. MWC is the place where Nokia just debuted its 808 PureView phone with a huge 41 megapixel camera and Samsung unveiled its Galaxy Beam phone that includes an internal projector.

It’s not the possibly venue for a massive home windows statement. however Microsoft needs windows 8 to be the working gadget that helps it thrive in an international where pill expansion is hovering and pc sales aren’t. consumers, who merely wish to be attached to the internet to test facebook and email, watch movies, and store, are increasingly more using devices rather than personal computers for the ones duties.

That’s why Microsoft is attempting to leverage its home windows computer hegemony into markets the place rivals have jumped beforehand. the company needs to turn that the next model of windows can give that easy internet get right of entry to on a variety of devices–the whole thing from conventional pcs to trim ultrabooks touch-pleasant drugs.

Microsoft’s Windows boss Steven Sinofsky has referred to Windows 8 as a “no compromise” operating system–one that can power high-end gaming machines that run Intel processors as well as trim tablets using ARM chips. When Microsoft gave its developers the first detailed look at the new operating system in September, Sinofsky talked about the importance of addressing the needs of mobile users.

“It was once that it used to be sufficient so that you can simply lift your pc round, positioned it dpersonal, plug it in and use it,” Sinofsky mentioned in his keynote deal with at the convention. “however now you wish to have units that you can use while you’re sporting them round or just seated more or less uncomfortably or reclined. a complete new method of the use of compositioneding has really arisen, and we want windows to reply to that.”
however trying to create an running system that cope withes this type of broad set of wishes has its own demanding situations.

“When you describe something as ‘no compromise,’ you end up with something that’s a giant compromise for all things,” said Gartner analyst Michael Gartenberg.

With Windows 8 on ARM, for example, Microsoft will offer a slightly different experience for consumers than the one they’ll get with tablets running the traditional PC x86 architecture with chips from Intel and AMD. The ARM system-on-a-chip architecture means that devices themselves can be thinner and lighter. But it also means that some legacy applications won’t work unless developers port those applications.

To make the transition easier, Microsoft said in advance this month that it could ship a model of its upcoming productivity suite, code-named workplace 15, for the ARM version of windows 8, so that you can be contact-enabled. And that version of place of business will run in the traditional windows laptop mode so that you can ship on the ARM devices.

“ARM (tablets) will have something that looks like a Windows desktop, but isn’t really one,” Gartenberg said.

In Barcelona, Microsoft will need to give shoppers a reason why to pick out a home windows 8 pill as a substitute of an iPad or Amazon’s Kindle fireplace. it’s going to want to provide a compelling vision for choosing its environment, one that makes its easy to jump from one home windows tool to another.

“Microsoft needs to show why consumers should care about Windows 8 in a world where the personal computer is not the hub of their digital world,” Gartenberg said.
