I think the only way is with a custom msgina.dll.

Ctlr+Alt+Del doesn't do anything on my images. I have used
MinLogon and not included task manager.

bug,

Download and modify Ginastub.dll to block CTRL+ALT+DEL.
A sample Ginastub code you find on www.xpefiles.com or www.codeprojects.com.

Also, you can search this NG archive (http://groups.google.com/group/microsoft.public.windowsxp.embedded?hl=en&lr=&ie=UTF-8) to see
more posts about the problem.
IIRC, even some code has been posted here.

bug,

The DisableCAD value determines whether users must press the CTRL+ALT+DEL key sequence to log on to Windows.
If the value of this entry is 0, the "Log On to Windows" dialog box is displayed as soon as the system starts. If the value of this
entry is 1, the Windows splash screen with the "Press Ctrl-Alt-Delete to

begin" message is suppressed.

I never heard of DisableCtrlAltDel value.

There is an undocumented way to disable CTRL-ALT-DEL on Windows NT/2000/XP using
the registry. I have got this to work successfully on XPe SP2 using WinLogon.

The key,
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\AutoAdminLogon (REG_SZ)'
is only supposed to have two legal values (according to Microsoft) "0" and "1".
"0" disables automatic logon of the account stored, and "1" enables it. However
if you set the key to "2", it will enable automatic logon AND disable CTRL + ALT
+ DEL sequence registration by windows on boot, effectively disabling Task
Manager, etc..

WARNING:
So that automatic logon works you will also have to set the "DefaultUserName"
and "DefaultPassword" values to the correct username & password. If you do not
set these correctly then you can end up with a machine you cannot get access to.

Again, here are the keys needed to be set:

* HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon :
AutoAdminLogon = "2"

* HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon :
DefaultUserName = "(the username to automatically logon)"

* HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon :
DefaultPassword = "(password for default username)"

NOTE:
I added a RunOnce action to the build to add the AutoAdminLogon entry to the
registry. However when I combined that with the 'Automatic logon' component
and built an image I ended up with an empty registry string for the autologon
username and autologon turned off (set to zero). The simplest solution
was to remove or disable Automatic Logon in the configuration, then put the
autologon username and password in the registry patch and let the RunOnce
action patch the registry with the correct autologon settings as well as
the CTRL-ALT-DEL fix.
