Unable To Skip User Account Creation During Windows 7 Unattended Install

Hello,

I am trying to create a fully unattended Windows 7 SP1 installation using Windows Deployment Services (WDS) and an image created using ImageX.  I have created two unattend files, one for WDS (works flawlessly) and one for the OOBE setup screens.

Despite trying different configurations in my unattend file, I cannot get it to stop prompting to create a new user account.  I've been searching forums and trying different settings for days, but am having no luck.  I just tried the suggestion from the bottom of this article - http://technet.microsoft.com/en-us/library/cc732729(WS.10).aspx - which says to add a domain account to the Administrators group through the unattend file.  This did not work.  I have also tried adding a local account through the unattend file.

I have no issue with the pc joining the domain (I prestage in AD first) and am not prompted for anything else (time zone, computer name etc.).  Could someone tell me what I need to do differently to make this work?  I need this to be fully automated so that I can deploy remotely to branch office.  Below is my unattend XML file:
