Follow these steps to remove LimeWire:

Open the LimeWire folder.
Open the folder UninstallerData.
Double click the Uninstall LimeWire icon (or something similar).
Follow the on screen prompts to uninstall the program.
Go to C:\Program Files and delete the LimeWire folder.

Set a System Restore Point, to prevent trouble if you make a mistake.
Go to Start, Run, type regedit in the box, and hit Enter.
At the top of the Registry Editor window, click on File, and then Export. In the Export range panel (at the bottom), click All, give the file a name, and then Save your registry as a backup to a location where you will be able to locate it easily if necessary.

Go to the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. If you find the value HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run\limeshop, delete it and reboot the machine immediately.

Remove these registry items (if present) with RegEdit:
