Sysprep Progress and Windows Assessment Tool in Sysprep

Hello,

I am building a Vista Enteprise image and am using sysprep with an
unattend.xml file. I have a couple of tweaks that I would like to add to
this process but not sure if they are possible or where to look:

1) In Windows XP, you were able to see the various screens when minisetup
run. Is there anyway to do this Vista? Right now, all I get is the default
wallpaper and the busy circle icon. Sysprep does complete successfully, I
would just like to see what its doing, while its doing it.

2) Is there anyway to turn off the "Please wait while windows checks your
computer's performance?" (Windows System Assessment Tool)? All my machine
types are the same, i already know what the rating is going to be, and this
just seems to add time to the process. Anyway to prevent this from running
during sysprep?

3) I'm using the skipuseroobe option, but I still have to create a user.
Is there anything else I can look at to stop this from happening?

Thanks.
