Titolo: ShutDown di Windows 2000 quasi riuscito .....

Ok, grazie mille per l'aiuto che  mi avete dato sin qui per fare lo ShutDown
di Windows 2000 ma ho ancora un problemino : il PC fa lo ShutDown
correttamente solo che poi non si come invece fa  Windows 2000
(Start/Esci/Arresta il Sistema)
quando arresti il sistema.
Dopo lo ShutDown mi appare infatti una finestra con risoluzion 800X600 che
mi dice: ORA E' POSSIBILE SPEGNERE il PC (o qualche cosa del genere).
Ho provato modificando il Registro di Sistema in modo da forzare lo
spegnimento del PC dopo che č stato effettuato lo ShutDown ma nulla č
cambiato nel senso che debbo poi spegnere manualmente il PC:
      Settings:
      Key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon]
      Name: PowerdownAfterShutdown
      Type: REG_SZ (String Value)
      Value: (0 = disabled, 1 = enabled)
Allego qui il codice che ho usato:

non so se te l'ahnno gia' detto, ma hai provato ad abilitare l'opzione ATM
dal pannello di controllo, opzioni di rispario energetico?

Ho provato ma non riesco a trovare l'opzione ATM: di che cosa si tratta?
:)
