At long last, and probably in response to the growing number of leaks, Microsoft has published an official "first look" of Windows 8.1 (Blue). As expected, the Start button is making a return (but the Start menu isn't), you can boot straight to the desktop, you can now view multiple Metro apps side-by-side, and the Metro control panel (PC Settings) has been beefed up to contain lots of important settings, such as screen resolution and power options.
