Here are the latest rumours for Windows 8.1.
Start button has returned with the icon the same as the charms icon.
MS will allow users to swap the start screen with an application list when the button is accessed. (i really hope this is true)
You can use your desktop wallpaper on the start screen.
You will be able to boot directly to the Desktop.
