Windows 8.1 Error On shutdown

I've updated my laptop's operating system from windows 8 to 8.1 but i keep getting the following error when i shutdown my system.



My brother is also having this error on his laptop, this error does not happen all the time but most of the time. Anyone know what could be causing this error and how to fix.
