Microsoft is planning to unveil its Windows 8 successor next month at a special press event. Inside sources from the Microsoft camp told The Verge that the software giant has set a tentative date for September 30th.
The goal is to detail upcoming changed to Windows as part of a released codenamed "Threshold." This date may change, but the Threshold version of Windows is currently in development and Microsoft plans to release a preview version of what will likely be named Windows 9 to developers on September 30th or shortly afterwards.
The Windows 9 preview will be similar to how Microsoft first let developers test Windows 8, with features not fully complete or missing. ZDNet claims updates will be pushed to users who install the preview on an automatic basis, meaning the release will change rapidly over the coming months before it's finally ready. Existing internal versions of Threshold include a new mini Start Menu, "Metro-style" apps that float in separate windows on the desktop, a virtual desktops feature, the removal of the Charms bar feature, and an early version of Cortana.
Microsoft is also making several UI changes to Windows 9, including some tweaks on the desktop to improve upon Windows 8.
Threshold will likely be changed to Windows 9 after the event has taken place in September. Microsoft is said to be planning an overview of key new features of the upcoming operating system, with a technical preview ready for developers and enthusiasts. Microsoft is also building a separate combined version of Windows RT and Windows Phone, and the company may take the time to detail this work during its press event.
