Sysprep and Settings Autologon Keys with FirstLogonCommands

Ran into small problem today when setting up a Vmware View Repurposed Thin Client. The behavior i wanted has the Windows 7 machine running sysprep. On first boot it autologon's to the local administrator account. On that first logon it runs all the nessary FirstLogonCommands from the sysrep unattended file. In those commands are the nessary commands to change the autologon to have it login to a local viewuser account that has had it window shell replaced. The problem was that the FirstLogonCommands where failing at setting the autologon registry keys correctly.

Problem
It turns out that because AutoLogonCount is set to 1, on logon it decrements it to zero. On logoff and reboot when Windows 7 sees the AutoLogonCount set to zero it deletes the keys "AutoAdminLogon", "AutoLogonCount", and "DefaultPassword" from the registry. Those same values I had just set for the ViewUser.

Solution
The easy solution is easy, I just have to add a command to delete the AutoAdminLogon key from the registry my self. Then Windows never goes back and cleans up the Auto Logon Registry keys that where just set.

<AutoLogon>
    <Password>
        <Value>password</Value>
        <PlainText>true</PlainText>
    </Password>
    <Domain>.</Domain>
    <Enabled>true</Enabled>
    <LogonCount>1</LogonCount>
    <Username>Administrator</Username>
</AutoLogon>

This is how it will look in the sysprep unattended file to set the autologon after the administrator autologon.
