The Windows Installer allows you to install and uninstall applications. The Installer contains a wizard, which helps guide users through the installation process. The Installer runs as a service on the Windows machine. To remove the Installer from the system, the service is stopped and unregistered. You can stop a Windows service in the Control Panel, and unregister the software from the Windows command prompt.

    Click the Windows "Start" button and select "Control Panel." Double-click "Administrative Tools." Double-click "Services." This opens a list of services running on your machine.

    Click the "Name" column header. This sorts your services alphabetically, so you can find the "Windows Installer" more easily. Double-click the "Windows Installer" icon to open its properties. Click the "Stop" button and choose "Disabled" from the "Startup Options" drop-down box. Click "OK" to save your settings.

  3. 3

    Close the Windows services window. Click the Windows "Start" button again and select "Run." Enter "cmd" into the text box and click "OK." This opens your Windows command prompt.

  4. 4

    Type "msiexec /unreg" into the command prompt. This unregisters and removes the Installer from the machine and the Windows registry.

    Reboot your computer. Since unregistering services changes values in the registry, reboot the machine for the changes to take effect.
