While I’ve been ripping off Virtual PC Guy I may as well stay at it. He has a great tip in his geeking out with WDS post suggesting that custom installation images can be built up in a virtual machine and captured from virtual rather than capturing the physical build. This allows for ongoing maintenance of the build without worrying about capturing the same image multiple times by taking a snapshot before SysPrep. It’s a great suggestion.
I’d actually geared myself up for this approach with the release of Windows Server 2008 R2 RTM, since Windows Deployment Services supports deployment of VHDs now, but I deflated myself a bit when I realised this was only a means of deploying for native boot from VHD rather than deploying a VHD to hardware as though it was a captured WIM. When I figured this out I went back to capturing physical images, and blindly overlooked this option. Nice one!
