To celebrate the one billion active users of Windows 10, Microsoft's Panos Panay posted on Intragram a video showing the evolution of Windows, along with Windows 10. The video reveals some features that are going to appear in Insiders the next period.
To be more specific, the video reveals a new Start Menu (Start Menu) which seems to eventually come to Windows 10. The new Start menu shows colorless boxes to pin applications without the color you selected. Live Tiles still exist.
The video also presents a new news File Explorer. In fact, it is the same modern UWP application that accompanies the Windows 10, but now it seems to have improved a lot. Microsoft gives priority to its development, as it will be used by default in the upcoming Windows 10.
