Introduction
Fast Start up is a new feature in Windows 8 that makes Windows 8 faster and different from previous versions of Windows. The reason of Fast Startup is that when a Windows 8 computer is shutdown, it actually goes into a hibernation state and all the settings and Kernel session are stored in the hiberfil.sys file located in the RAM of your computer and your computer is not completely shutdown.
