NO! This has been explained already elsewhere in the thread in multiple 
different ways:

'Hibernate' saves the current user and OS states, so that by default 
they will be restored when the PC is next powered on.  When the PC is 
next powered on, all the user's running programs will be restored.

'Shutdown' in Windows versions >= 8 with 'Turn on fast start-up' enabled 
saves a state of the OS equivalent to being fully booted but no user yet 
logged on, so, unlike 'Hibernate', no user state is saved.

'Shutdown' in Windows versions >= 8 with 'Turn on fast start-up' 
disabled, or in versions <= 7, saves nothing, so a full boot of the PC 
will occur on every power up, unless on the previous shutdown the PC had 
been hibernated.
