Systems Deployment

I am building a Windows 8 image for my organization.  We use SCCM 2012 R2 to do OSD over PXE.  I use an answer file for the deployment which I created in Windows System Image Manager.  One setting I would like to implement as part of the answer key would be this regedit:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
 "AutoAdminLogon"="0"
 "DefaultUserName"=""
 "DefaultPassword"=""
 "DefaultDomainName"="DOMAIN NAME"

I can't find the appropriate component in the Windows System Image Manager to make the above changes.  Can you help me please?
