Clear last logon user name

Question

I have seen various threads that you can clear the last logon username by registry or policy but I only want to do it once - i.e. logon as local administrator, do some work and then reset the logon screen so it is blank fresh for user. In XP it was simply
a question of clearing a couple of registry keys - any way to do the same in Win 7 ?
Thanks

Hi Ian
It isn't clear what exactly you are trying to do?
If you enable the policy to clear the last logon user name, this changes the logon screen to one that does not display any user names. Each user must type their user name and password to log on.
If you disable this policy, then the standard logon screen is displayed with all user names visible. The user is still required to type their password.
It would be very easy to quickly switch this screen using the registry.
Create 2 registry files.
1. DontDisplayLastUserName_Enabled.reg with the following text.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"dontdisplaylastusername"=dword:00000001
2. DontDisplayLastUserName_Disabled.reg with the following text.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"dontdisplaylastusername"=dword:00000000
To switch the logon screen simply Merge the appropriate file.
Hope this helps.
Thank You for using Windows 7
