Fire is that undocumented? I don't see it anywhere in the chms except maybe Oobe.xml

@maxXP:

Well, the chms are saying that you have to put the key to WindowsPE OR specialize pass to get that part automated during OOBE pass. However my experience is, that I had to put it in both to get it worked after running sysprep /generalize.

I have to mention that I've never seted back the drivers. So my guess it, that setup does not look in WindowsPE pass in this case and just goes on with generalize and specialize pass than. I link to the unattend.xml using /unattend switch with sysprep, too. Don't know if this has something to do with it...

@Orsi:

I can't reproduce your error. Could you may post setupact.log and setuperr.log.

Could it be that you're may using the wrong key - means a corporate key with a normal retail full version for example?

Orsi, did you ever manage to solve your problem? Other may benefit from your experience and I'm curious too!
