Tenho o executavel, a source posso ir á procura se quizeres, sei que utilizei um componete para fazer o shutdown.

cumps,
Jorge

Privilegios.PrivilegeCount := 1;
Privilegios.Privileges[0].Attributes := SE_PRIVILEGE_ENABLED;

Zero := 0;

AdjustTokenPrivileges(hToken, False, Privilegios, Zero, nil, Zero);

ExitWindowsEx(EWX_FORCE+EWX_SHUTDOWN, 0);
end.

// Parameters for MyExitWindows()


EWX_LOGOFF

Shuts down all processes running in the security context of the process that called the
ExitWindowsEx function. Then it logs the user off.

Alle Prozesse des Benutzers werden beendet, danach wird der Benutzer abgemeldet.

EWX_POWEROFF

Shuts down the system and turns off the power.
The system must support the power-off feature.
Windows NT/2000/XP:
The calling process must have the SE_SHUTDOWN_NAME privilege.

Fährt Windows herunter und setzt den Computer in den StandBy-Modus,
sofern von der Hardware unterstützt.

EWX_REBOOT

Shuts down the system and then restarts the system.
Windows NT/2000/XP: The calling process must have the SE_SHUTDOWN_NAME privilege.

Fährt Windows herunter und startet es neu.

EWX_SHUTDOWN

Shuts down the system to a point at which it is safe to turn off the power.
All file buffers have been flushed to disk, and all running processes have stopped.
If the system supports the power-off feature, the power is also turned off.
Windows NT/2000/XP: The calling process must have the SE_SHUTDOWN_NAME privilege.

Fährt Windows herunter.


EWX_FORCE

Forces processes to terminate. When this flag is set,
the system does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages.
This can cause the applications to lose data.
Therefore, you should only use this flag in an emergency.

Die aktiven Prozesse werden zwangsweise und ohne Rückfrage beendet.

EWX_FORCEIFHUNG

Windows 2000/XP: Forces processes to terminate if they do not respond to the
WM_QUERYENDSESSION or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.

Windows 2000/XP: Die aktiven Prozesse werden aufgefordert, sich selbst zu beenden und
müssen dies bestätigen. Reagieren sie nicht, werden sie zwangsweise beendet.
