Automatic power off on shutdown in virtual environment

(Article ID: 001516)
Summary

Windows NT 4 server and workstation installations may not "power off" after a shutdown command while running in a virtual environment (i.e. VMware). Instead of the virtual machine powering down the message "It is now safe to turn off your computer." is displayed.

Step-by-step instructions

To change this behavior do the following:

  1. Obtain the file hal.dll.softex.
    NOTE: It is included with Windows NT Service Pack 4 and is also available with this article.
  2. Rename the file %SYSTEMROOT%\system32\hal.dll to
    %SYSTEMROOT%\system32\hal.dll.sav.
  3. Start Registry Editor (Start>Run>regedit).
  4. Navigate to the following registry key:
    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.
    NOTE: HKLM is the abbreviation for HKEY_LOCAL_MACHINE.
  5. Look for a value called PowerdownAfterShutdown.
    NOTE: If this value does not exist, do the following:
    1. Click on Edit.
    2. Click on New.
    3. Select DWORD Value.
    4. Type PowerdownAfterShutdown and press ENTER.
      NOTE: Capitalization does count!

  6. Double click on the PowerdownAfterShutdown value.
  7. Type 1 and press ENTER.
    NOTE: Type 0 to disable powering down at shutdown.
  8. Close Registry Editor.
  9. Restart the computer.

There may be decreased performance with the virtual machine after this change takes place.
