Ok, i have done some research and if there is any programmers who use :
VB, C, C+ or Delphi could they check the following links and see if it is possible to create a vds dll.

There is an undocumented way to disable the Ctrl Alt Del key sequence on Windows NT/2000/XP using the registry.
The key, 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon (REG_SZ)' has only two legal values, according to Microsoft: "0" and "1". 0 disables automatic logon of the account stored, and 1 enables it. The strange thing is that 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... Of course for this to work you will have to set the "DefaultUserName" and "DefaultPassword" keys to the username to automatically logon.
The easiest way to kill the Ctrl-Alt-Del sequence.
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)"

Hopefully some bright spark can make us a dll or dsu !
