Hello bomber58
The start button right-click uses the traditional shut down (the one used from Windows 95 to Windows 7's start menu). The new Windows 8 fast shutdown (or fast startup) is only available from the Settings charm.
- Classic Shutdown: Right-click Start, click Shutdown, click Shutdown
- Fast Shutdown: Click Settings, click Power, click Shutdown

If you shut down from the WIN+X menu in Windows 8.1, it will perform a full shutdown instead of a hybrid shutdown even if you have Fast Startup turned on.
