How to Uninstall Left Over Program Files

It's not uncommon for users to find left over program files even when the uninstalled application is no longer present. This can happen even when a program is removed through the Windows "Add/Remove Programs" utility. This old software references remain in your system as a result of malfunctioning uninstallers, or caused by removing an application incorrectly. In any case, these orphan references can significantly slow down your system in the long run. To remove them from your system completely, you will need to edit the "Registry." Proceed with caution when making changes in the Registry Editor, since deleting an incorrect key could potentially jeopardize the stability of your system.
