Windows 8 includes a few new features that were first introduced with Microsoft’s mobile operating system Windows Phone. The Start screen, Metro-style apps, and Lock screen were first introduced with Windows Phone and are now part of Windows 8. The Lock screen appears when you boot your PC or resume your PC from hibernation. The main purpose of the Lock screen is to provide some basic and useful information such as battery percentage, date and time, network connectivity, and notification from apps. To unlock the lock screen and to proceed to the logon screen where you enter the account password, either press a key on the keyboard or swipe the screen up using the mouse or with your finger if you are on a touch-screen device. Note that the Lock screen doesn’t provide any shut down options and you need to proceed to the logon screen to for these options. Windows 8 offers more customization options than previous Windows versions. The lock screen can be customized in a number of ways and one can even disable the same under Group Policy Settings.
