A new proof-of-concept application from Microsoft's research arm integrates elements from the Windows OS and its Windows Azure cloud infrastructure to let users share files from their desktops with Web users via social networking.

In addition to leveraging Windows and Windows Azure, the Social Desktop also uses Silverlight, Microsoft's cross-browser runtime and player for sharing multimedia files. Users must be running Silverlight in a browser to view the items that people using Social Desktop choose to share.

sMicrosoft's Razorfish has chosen Rackspace to host the development of new Web sites and applications rather than wait for its parent company to release its own cloud-hosting platform Windows Azure.

Rackspace, formed in 1998, was a private company until it began trading on the New York Stock Exchange last August. The company offers a range of managed-hosting and cloud-hosting services.

Cloud computing and hosted services are becoming an increasingly attractive options for companies that don't want the hassle or expense of building out their own IT infrastructure, particularly now as the global economy is in a recession.

Just weeks before the trial on whether or not Microsoft tricked millions of customers into buying PCs incapable of running Windows Vista back in 2006, the judge Wednesday removed the plaintiff's "class action" status.

The court stopped short, however, of dismissing the case altogether.

What the ruling means to the case ? known as the "Vista Capable" lawsuit ? at this point is unknown. However, a loss in a class action suit with potentially millions of class members could result in millions or even billions in damages.

Prithvi Raj, a product manager for Microsoft, demonstrates the new Windows Mobile 6.5 running in an HTC touch-screen handset at the GSMA Mobile World Congress 2009 in Barcelona.

Microsoft is trying to sell the world on the notion of a "Windows phone." The first part of that effort is simple. It's a rebranding exercise. Although Microsoft will continue to sell its Windows Mobile operating system, it is going to put its marketing muscle behind the term "Windows phone" to describe the devices that run its software.
