Windows 7 AutoUnattend.xml - User & PC Name

So I've been asked to research Win7 images and the best way to create and deploy them. We don't have MDT 2010 up yet, so I'm stuck using a custom install.wim along w/ the unattend.xml file.

Question #1

How can you stop Win7 OOBE welcome screen from making you create a local user account? After Win7 finishes its text based setup, I want it to boot into Windows as Admin bypassing the welcome screen (create user/change PC name). This way desktop support can -

1. Change the PC name
2. Join the domain, reboot, and be done
3. End user logs in, process complete

There is no need for them to do a Audit mode w/ reboot. The domain accounts already exist. I don't want local users being created.

In Win XP you could edit the sysprep.inf so that you had -

[GuiUnattended]
AutoLogon=Yes
AutoLogonCount=1

Which would allow you to log in as admin the first time after sysprep, join the domain, etc. How do you do this w/ Win7? I can only get it to log in as admin in systemAudit mode, I want to do it in OOBE.

Hopefully I just missed something. Like I said, I'm new to automating Win7 setup.

I was able to successfully solve this exact problem by looking at this website:

Sysprep a Windows 7 Machine

With the unattend.xml file that I have, it prompts for a PC name first thing, then creates the local administrator account and automatically logs in one time, joins to the domain via my JOINDOMAIN.VBS script, installs our AntiVirus program, installs out network management agent, and activates windows automatically with KMS. Then it ends by initiating a system reboot with a 10 minute timeout clock. That way if an admin has to leave the machine during the imaging process, it won't stay logged in to the local admin account. So what you are asking about is definitely possible. Just make sure your unattend.xml file is built correctly.
