Okay, the last step:
Look at the left bottom corner of your desktop. There is a button saying "START". Click it. Now look for "Run...". Click it. Now type "regedit" into it and click "OK". A window will open. There you go to "Local Machine". Look for the folder "Software". Open it. Then look for the folder "Limwire". Right click the folder and delete it.
That's it.
