A new leak from Evan Blass reveals the name of Windows 10X, an alleged fork of Windows 10 designed to run on dual-screen devices. Rumors of a dual-screen Surface device from Microsoft have circulated for months, and many believe that a new dual-screened device will be shown off at the October 2 Surface event.

Blass's account is private, so many users won't be able to see the tweet, but as reported by The Verge, Windows 10X will run on the rumored Centaurus device. Windows 10X is also reportedly the same thing as Windows Lite.

Blass's tweet does not include any images of Windows 10X. It does state that the operating system is designed for dual-screen devices like Centaurus.

In addition to rumors around Centaurus, there are also reports that suggest a new Surface Pro, a new Surface Laptop, and a Surface device powered by an ARM processor will be announced at the Surface event.
