   Fast startup changes the start from maybe 15 seconds to 5 seconds (fast   
   machine).   
   It is intended to get that screen lit up quickly, to impress your friends.   
   (Some people have boot contests, and they would like this.)   
      
   If used to be, you got a fast boot time, by owning a "mighty" processor.   
   That was the purpose of the boot contest, was to show how you must   
   have spent a lot of money on the machine. Fast start allows you to cheat.   
      
   It's Windows kernel+drivers hibernation, the session is not saved.   
      
   During the five second boot, the blob is read in from hiberfil.sys,   
   and the drivers are warm started (data arrays initialized). If any   
   new hardware was plugged in, it will eventually be discovered (perhaps   
   after the desktop has been painted).   
      
   But Fast Boot is also a "handcuffs", as it prevents multi-boot.
