Windows 7 - Username field not populated after login

Hi all,
 
We are about to start deploying Windows 7 in our environment.
 
We have found that when a domain users logs into a newly built (via SCCM 2012) Windows 7 machine and logs back out, the username is not retained. A username has to be entered everytime.
 
Have any of you come across this before?
 
The 'remember last username' group policy is disabled.
 
Any help/guidance would be appreciated.
 
Regards,
 
Jay.

Jay,
The relative setting in the security policy (secpol.msc) should be "Interactive logon: Do not display last user name", at the following location:
Security Settings > Local Policies > Security Options
By default, this should be set to "Disabled", which will allow the last logged on user name to be displayed at the logon screen.  Here's the corresponding registry value:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System|dontdisplaylastusername:0
 
Is this the setting that you verified?

Hi Jeremy, this is exactly what I was looking for.
 
I failed to look at the registry value as the registry change was correctly made on the Windows 7 image when it was created - something was changing the registry value when the image was being applied via SCCM which meant the last username was not being displayed.
 
I should have checked the registry first.
 
Many thanks for replying.
 
Jay
