No word on hardcover edition...
The "official" Windows Vista Resource Kit is now available and covers topics such as administering group policy, files and folders, programs, and deployment and configuration among many other useful topics.
"The official Windows Vista Resource Kit
walks corporate users through the deployment, configuration and
management of the operating system. The book dedicates more than 1,500
pages to in-depth technical guidance on automating deployment,
implementing security enhancements, and troubleshooting for Vista,
which was released to corporate users in November."
Well at 1500 pages I would bet it covers a great deal of everything you needed or wanted to know about the workings of Vista. Read more at the article below.
