A great new technet blog post was added yesterday that provides an overview of the deployment tools for Windows 7. You can see how to deploy from media, a network share or from a WDS (Windows Deployment Services) implementation. You'll find the blog post here: http://edge.technet.com/Media/Deploying-Windows-7/
I am in the process of shooting some videos on the Windows 7 deployment process, so watch out for my post about the video availability. I'm still toying around with the idea of a dedicated website for Windows 7-related videos, but for now I'll probably just HD YouTube the videos and link to them here.
Enjoy the new TechNet post.
