One of the biggest controversies with Windows 8 (ok, it’s the second biggest next to making the Metro UI default) is Microsoft’s decision to remove the Start button/Start Menu we’ve all known and loved since Windows 95 from the taskbar. However, in it’s place they have added a hidden menu that provides quick and easy access to many useful system tools such as Device Manager, Programs and Features, Control Panel and Command Prompt just to name a few. This is yet another feature Microsoft has added to make navigating Windows 8 easy for those who prefer using a keyboard and mouse.
To access this menu, move the mouse cursor to extreme bottom-left corner of screen and right-click. You now have access to the hidden system menu. You can also access it using Windows key + X.
