ONLY FOR WINDOWS USER !!!

More than 80% percent desktop user are using windows as there main operating system and almost
 every user know how to make a new folder on the desktop.User can easily rename that the folder
but to rename that folder name as: CON.
It's seems easy but it is impossible to create a folder with name "con" on the desktop and it result into an error

                    

                

The reason behind this is that con is a type of system action and you can't make folder name
same as system action.
The some other system action are as follows:
CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, 
LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9
