Microsoft demonstrated a number of new features in Windows 8.1 earlier this week, but the company briefly showed the return of the Start button and avoided any details on how it visually works. During Computex this week the company took the time to show the Start button fully. In the video below you can see how Microsoft is adding options to show the All Apps view when the Start button is activated. The animation of the Start button switching between the desktop and Start Screen is clearly shown too with the new support for desktop wallpapers on the Start Screen. Microsoft will deliver a preview version of Windows 8.1 on June 26th.
