UninstallButton is a simple application which makes it easier to find the uninstaller for any given application.
If you want to remove a program, then, there's no need to go hunting the Start menu for an Uninstall link (which isn't always there, anyway), or to launch the Control Panel "Uninstall" applet (which is really rather slow).
Instead, just right-click the program's executable file or a shortcut to it, select "Uninstall with UninstallButton" and the program will find and display the uninstaller for you. Choose this and your unwanted application will be removed. (This uses the standard uninstaller; UninstallButton doesn't help it in any way.)
Or, if that's not convenient, simply run UninstallButton and choose to filter "by window". UninstallButton will then display every program currently running with a top-level window open. Choose the program you don't need, and again you'll see the uninstaller, and can remove it with a click: very easy.
