* means that any code that calls the function has to execute the chosen action (shut down,

* - When this function is called in Windows XP, it shows the classic dialog box regardless if

* SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\LogonType is enabled or not.
|
|
* - When the Help button is pushed, it sends the same return value as IDCANCEL (0x00), but
