Microsoft is tipped to unveil its latest desktop OS, Windows 9 "Threshold", on 30 September.
The Verge claims a press event showing off the new OS is tentatively set for 30 September although it warns "this date may change".
Microsoft has released two tiny teasers for Windows 9, codenamed "Threshold". The first showed a reimagined Start Menu combining the familiar design of the menu that had been in place from Windows 95 to Windows 7 with the "Modern UI" layout from Windows 8. The second showed Windows Modern apps running in a window on the desktop, rather than full screen.
Other than that, the company has kept schtum on any official news, but that hasn't stopped a steady trickle of leaks coming out.
On 11 August, Microsoft-watcher Mary Jo Foley reported Threshold will feature virtual desktops. The same day, Neowin reported Cortana, Microsoft's virtual PA, will be integrated into the Windows 9 Desktop.
The 30 September release date claimed by The Verge fits in with earlier rumours of a late September or early October launch.
However, this northern autumn's release will only be a preview, with the full version expected in the northern spring of 2015.
