[Question] Shutdown Reason Codes

[Maelstorm]

How do you use the shutdown reason codes for shutdown.exe? I have found the reason codes on Microsoft's website here, but the problem is the Major reson code. How do you translate the major reason code 0x00020000 into something that will be understood on the command line? I have tried something like this:

shutdown -r -f -t 120 -d p:2:17 -c "Your computer has been updated."

In the system log, I get this:

Event Type:	Information
Event Source:	USER32
Event Category:	None
Event ID:	1074
Date:		1/14/2006
Time:		11:15:29 PM
