I'm crazy about Windows 8.1. More specifically, I absolutely adore the secretive "Navigation" menu buried deep within the new OS. Right-click the desktop taskbar, select properties, and open that fresh, new Navigation tab to unlock a legion of hidden options that let you boot straight to the desktop, disable the upper "Hot Corners," and force the Start button to act more like the Start Menu.
The Navigation menu's basically a love letter to PC power users, and its inclusion means it's possible to banish the modern UI and focus on the desktop without all the hoop-jumping that was required to ditch Metro in Windows 8 vanilla.
