Suppressing the "reason" for shutdown on Windows Server
Solution 1:
You will need to modify the group policy that is applied to the servers. Open up the Group Policy Management Console and navigate to Computer Configuration >> Administrative Templates >> System and select "Display Shutdown Event Tracker." Disable that option.
Solution 2:
If you do not want to change via Polices you can always issue the shutdown command to avoid the question.
shutdown /s /t 0
/s = shutdown /t = time till shutdown 0 = immediely
Solution 3:
Running the following as an elevated admin:
reg.exe add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Reliability" /v ShutDownReasonOn /t REG_DWORD /d 0 /f
and then logging off and on again should to the trick.
This is quicker than using group policies which you should use when you are in a domain and want to apply this change to many servers.
Solution 4:
I'm sure the OP has found the other answers useful but future readers may be interested in a powershell version. Works out of the box in 2008 or up, and maybe in 2003 if powershell is installed.
if ( -Not (Test-Path 'registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Reliability'))
{
New-Item -Path 'registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT' -Name Reliability -Force
}
Set-ItemProperty -Path 'registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Reliability' -Name ShutdownReasonOn -Value 0
#
or a .reg file version. Install with "regedit /s Disable_Shutdown_Event_Tracker.reg"
Disable_Shutdown_Event_Tracker.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Reliability]
"ShutdownReasonOn"=dword:00000000
