Well I've had semi success with creating a universal company image for multiple platforms, my only concern is this!

I've used BTS Driver Packs with KTD option and so far after imaging 4 complete different PC's everything has turned up PERFECT. My concern is that the after the image is loaded it detects the new hardware and installs the drivers automatically, however I feel this is not a "CLEAN" way doing so! The old hardware drivers installed, how does windows treat them?..

I believe the most efficient way doing this would be to sysprep the PC and have the OS re-check for system drivers on the 1st boot, however I don't have any Idea how to achieve this! Any help on this would be great.!

if you used the KTD method al you need to do is run sysprep. As I recall KTD adds the driver paths to the registry so that they can be found later so this will still work on the first boot after sysprep as long as you don't add more with the sysprep.inf file.
