Windows PE 2.0 is the core deployment foundation for Windows Vista. It is designed to make large-scale, customized deployments of the new Windows Vista operating system notably easier. When Windows Vista launches, Windows PE 2.0 will be available to all Windows Vista corporate customers. [Windows PE for Windows XP will remain exclusive to customers who have a Microsoft Software Assurance (SA) agreement.] Windows PE enables users to inject drivers, configure Windows Vista offline, provide recovery solutions as well as diagnose and troubleshoot system problems.
