James Senior just gave us a demo session on Vista. One of the nice things was the back up the PC to Virtual PC 7. Yes this will take a complete snapshot of your pc in a format that can be run in VPC so that you can run it on another machine till the PC is fixed or what ever.
What would be really great if this was included in the Server version. That way after an install you could take snapshots of all the machines and then support could recreate the exact environment that exists at the client site.
This would also be an ideal way to build demo decks.
Fingers crossed for the future.
