I have already read the :

Is it possible to reset FTDI virtual com ports enumeration, we easily get hundreds of COM ports in production environment

topics which was pretty interesting !

But I got a problem, apparently I can't delete the ftdi driver, so I can't use the previous conclusion of the topic... I'm really stuck and bored of this problem, my com port number is 132 !

Does someone have another solution ?

What do you mean by "can't delete the driver"? Have you tried uninstalling the unused virtual com ports as shown here?
