Tech Tip: Enable automatic power down in Windows NT

By making a quick registry edit, you can configure an NT system to automatically shut down when the user exits. Find out how.

One nice feature that Microsoft included in Windows 9x and other editions that it didn't include in Windows NT is the automatic power down feature. You're probably already familiar with this feature, which you can recognize by Windows' message, "It is now safe to turn off your computer."

Although you can't make that message appear in NT, you can still create the same result. By making a quick registry edit, you can configure an NT system to automatically shut down when the user exits.

Follow these steps:

  1. To open the Registry Editor, go to Start | Run, enter regedt32 in the Open text box, and click OK.
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.
  3. Double-click the PowerdownAfterShutdown entry, and change the value to 1.
  4. Exit the Registry Editor, and restart the system.

Successful implementation of this tip requires the installation of Service Pack 4, and you must have applied all flash BIOS updates. In addition, some versions of the AwardBIOS don't support this registry edit.

Note: Editing the registry is risky, so be sure you have a verified backup before making any changes.
