Could this be the most evil office prank to play on your co-workers?

Everyone loves a good office prank - except of course the victim - and this one could be the best yet!

One of the worst things about working with a computer is that occasionally the machine needs to do an update which can either take a few minutes or a few hours - and the quicker you need it to be done the longer it takes.

Seeing the phrase 'configuring Windows update' is enough to bring a grown adult to tears on a Monday morning and now because of this message, you can become the King or Queen of the office pranksters.
