[atcrvr]

I Install the SP4 and when i shutdown my pc I need to turn off manualy. Before the install the SP4 when i shutdown my pc turn off auto. I read that i need to install the SP5 and I installed, but now the shutdown works like a restart.
Any Idea ???
Thanks in Advance.

This auto shutdown is a utility that comes with the system or system board installed. Some companies have updated the utility for sp4 and most have not for sp5 yet. Go to the vendor of your system (eg. hp's sight has the update for sp4 but not sp5). If you need more info, let me know.

Issue


When selecting START/SHUTDOWN in Windows NT 4.0, system will restart instead of actually powering off.


Procedure


Modify the registry to fix this problem.
Click START/RUN, enter REGEDIT.EXE and press the ENTER key to continue.

Go to HK_Local_Machine\Software\Microsoft\WindowsNT\CurrentVersion\WinLogon, and Change the registry key "PowerDownAfterShutdown" from 0 to 1.

Exit the Registry editor and restart NT for change to take effect



But when I go to change the parameter is already set ??.
