Windows Vista OS setup is built on an entirely new set of technologies than previous versions of Windows, and as a result the process of creating OS images and creating and using unattend files is different than you might be used to from the past. If you are planning to create and deploy OS images for Windows Vista, take a look at the Windows Vista deployment step-by-step guide for some helpful information.  The following sections are included in the deployment guide:

• Tools and technologies
• Requirements and prerequisites
• Step 1: building a lab environment
• Step 2: building an answer file
• Step 3: building a master installation
• Step 4: creating an image
• Step 5: deploying an image
