Installing and deploying workstations or servers at enterprise scale has never really been all that fun, despite plenty of tools to create system images, perform unattended installations, and so forth. Windows Vista and 7 made the game harder, with hoops to jump through if you want to Ghost a golden image.
Which makes me very interested in the Windows AIK for Windows 7 and Server 2008 R2. You can down load this tool at http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=5753
If you get a chance to try it too, drop me a note and tell me how it works for you. Lots of us will be interested.
