How to stop shutdown in progress

Well this work for me very well. As i am not good at memorizing, every time i hit shutdown button i realize that i forgot to do something, and then i have to wait for my pc to shutdown.
So that i can restart the pc and do what i wanted to do.But i found a great idea to stop shutdown in progress. Now i can terminate shutdown.
Here is the trick

All this while when pc is terminating programs to shutdown, quickly press windowkey + R
then type shutdown -a. and hit enter it will stop or abort shutdown.

Or

If your pc is very fast i recommend you to create a shortcut icon for terminating shutdown
you can do it by rightclicking on the blank space on the desktop-> new-> click on shortcut
type "shutdown -a" without quotes click on next.
Name it whatever you want(default name is shutdown) and then click on finish
now whenever u want to terminate shutdown double click on this shortcut u created.

Thanks
