Windows Uninstaller makes use of the default uninstallation utility. The advantage of Windows Uninstaller over the default utility is the fact that you don’t have to open the Programs and Features dialog box and look for the application through the list. Once you install the app, the Uninstall button is automatically added to the context menu of executable files. For instance if you are browsing through the Program Files folders and come across an unwanted application, you can just right-click its executable file and select the Uninstall option.
So if someone has to locate and go through each folder of the installed applications, why not just use the default utility? Well, that is where this tool really shines. Other than the context menu in the Windows Explorer, it also allows you to uninstall application through their Start Menu and Desktop shortcut entries.
Just like the application files themselves, you can just right-click their shortcuts and choose the Uninstall option to uninstall the corresponding tool.
Windows Uninstaller uses the default uninstallation method, so you will need to have the uninstaller for the application already available in order for it to work. This should hold true for most applications that come with properly built installers that also provide an uninstaller with the package, but some applications that aren’t provided this way by their developers might not work with the method. The applications works on both 32-bit and 64-bit versions of Windows XP, Windows Vista, Windows 7 and Windows 8.
