I tried this out on my brother earlier it was so funny!! Go to start, settings, control panel and then mouse. find the option that says double click speed. where it says set the speed, set it a fast as u possibly can!! now when the victim tries to double click something they will need to do it as fast as you did! this will really annoy them because everytime they try it and dont do it fast enough it will give them an option to rename the file!! it so funny!!
