Neowin reports,via unnamed sources, that the feature is similar to the virtual desktop that's available on the Linux-based OS Ubuntu. Basically, it allows for more than one desktop to be on screen at once, each running their own applications.
While Microsoft may indeed be testing this feature in Redmond, even Neowin admits that it may not make it in the final shipping version of Threshold. However, it certainly would be a huge addition to Windows. Indeed, a few weeks ago, Microsoft's chief operating officer Kevin Turner claimed that the next version of Windows would have [some "game changing" features]http://www.windowscentral.com/microsoft-next-version-windows-will-have-game-chang) for enterprise users. Adding virtual desktop support for business users would certainly qualify.
Microsoft has already admitted that the next version of Windows will include a more traditional Start menu for the desktop, but one that will still have some "Modern" UI features. The current rumors claim that Microsoft might offer a public preview of Threshold, which may or may not be called Windows 9 when it is officially released, this fall. The final version may launch sometime in the spring of 2015 and there are rumors Microsoft might release it as a free update for Windows 7 and 8.1 users
What do you think about the possible prospect of the next version of Windows including support for virtual desktops?
