Introduction
Windows 8 has many new features, like the Start Screen, Charms Bar etc. In Windows 8 the Start Menu has been replaced by the Metro Start Screen. The Metro Start Screen is just like the Start Menu in previous versions of Windows but the Start Screen displays all applications using the Metro Style. The Windows 8 Start Screen allows the background color and style to be customized.
Previous versions of Windows only allow the Desktop background image to be changed and if you want to change lock screen background you can't do that but Windows 8 allows the Desktop background as well as the Start Screen and Lock Screen to be changed. The Windows 8 lock screen also allows the custom image on the lock screen to be set.
