Microsoft Corp sent out invitations for an event on October 6, where it is expected to unveil new devices that run on Windows 10, its latest operating system.
Microsoft is expected to unveil devices such as the Surface Pro 4 tablet, the Microsoft Band 2 wearable fitness tracker and the latest Lumia smartphones at the event.
Microsoft launched Windows 10 in July, almost three years after the launch of its previous operating system, Windows 8.
The new OS, designed to work across laptops, desktops and smartphones, is part of the company's push to win back lost ground in tablets and mobiles.
