i believe there are 2 ways of actually doing this right what i usually did was i looked at my toolbar i opened it fully and if you see limewire right click and click exit

and that jar thingy go to ur program files and open your limewire folder and look for the file it says you need to remove and t get to ur program files it is
My computer>main drive(usually C or D)>Program Files>Limewire

i hope this helps you in the future
