Is your computer a domain member? That checkbox is only available in
stand-alone installations.
If your computer is set up to log on someone automatically you can change it
directly in the registry by changing some values in the registry at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Set AutoAdminLogon to 0
Delete the DefaultPassword value

Your question may already be answered in Windows Vista Security:
