Is it dangerous to use the windows' shutdown.exe command to turn off the
computer?

I use the following command in autoit to turn off my laptop, if a timer
runs out
Run(@SystemDir & "\shutdown.exe /f /s /t 10", "", @SW_MAXIMIZE)
It works fine most of the time, but occasionally I get the BlueScreen when
turning the computer on, usually before the log on screen and after the
Windows logo animation completes. Is this because of turning off the
computer directly using the shutdown command, or can there be other
issues? I should point out that when ever my autoit script shuts off the
computer, usually there are multiple browsers with multiple tabs open,
along with other applications running. So I want to know,
What is the difference between shutting of the computer through the start
menu, by directly pressing the power button, and by issuing the shutdown
command from the autoit script? Is abruptly shutting down the computer
using the shutdown command while other user applications are running
dangerous in any way?
My OS is Windows 7 and computer is a laptop
