|  | Preparing a Reference Computer Configuring a Reference Computer
Install and configure applications. An application should be included with an image only if all users need that application at the time of deployment. Test the configuration. Test Windows XP Professional and all applications before you create an image. After the image is copied to a shared folder or compact disc, you will not be able to reconfigure Windows XP Professional or any application included in the image. If you need to make any changes, you must create a new image.
| Important: When you have achieved the correct configuration on the reference computer, shut down the computer to prevent any unwanted alterations to the configuration.
