What Does Uninstaller Mean?An uninstaller is a program or tool that is part of an application bundle used with Windows operating systems (OS). It allows a user to safely uninstall an application by running a program and following a series of prompts that warn users about the application's removal.
After running an uninstaller, traces of an application still requiring removal may remain, usually in the system registry. These should be removed individually or by using the control panel's add/remove command. In most cases, the uninstall tool is the easiest way to remove an application.
