Original KB number:   2001061


After reboot from a manual shutdown (START->Shutdown), the Windows System Eventlog shows two events 1074. The first entry contains the correct reason code provided by the user, the second looks similar to:

Log Name: System
Source: USER32
Date: <DateTime>
Event ID: 1074
Task Category: None
Level: Information
Keywords: Classic
User: Computername\Administrator
Computer: Computername
The process C:\Windows\system32\winlogon.exe <computername> has initiated the power off of computer <computername> on behalf of user <computername>\Administrator for the following reason: No title for this reason could be found
Reason Code: 0x500ff
Shutdown Type: power off
Event 0x000500FF (System Failure) is written to the SEL (System Event Log) even if a different shutdown reason was provided by the user who initiated the shutdown.


Microsoft has confirmed that this is a problem.


Microsoft will address the problem in future releases.


Use shutdown.exe to initiate the shutdown, run below command (for example) from the elevated command line:

shutdown.exe /r /d P:4:2

This will result in an event log and SEL entry with reason code 0x80040002.
