You can reinstall LW & then uninstall it, but if you do that you need to make sure that you don't have a version already running in task manager (or you won't be able to install a new version).

Or you could do a search like I said before & delete what you find, that should get rid of LW.

Just make sure that you hadn't changed the location for saving from the default...if you did change your saved location to a folder with limewire in the name, you could end up deleting your downloads
