Parameters
-L
Log out of the current user. This is the default setting. -M ComputerName is preferred.
-S
Disable the local computer.
-R
Shut down and restart.

Specify the computer to close.
-T xx
Set the timer used for system shutdown to xx seconds. The default value is 20 seconds.
-C "message"
Specify the message that will be displayed in the message area in the system close window. It can contain up to 127 characters. The quotation marks must contain messages.
-D [u] [p]: xx: yy
Lists the cause code for system shutdown. The following table lists different values. Value description
U specifies the user code.
P specifies the planned code to close.
Xx specifies the main cause code (0-255 ).
Yy specifies the secondary cause code (0-65536 ).
/?

Note
Once the primary and secondary cause code is specified, you must first define the cause code for each computer that plans to use a specific cause. If no cause code is defined on the target machine, the event viewer cannot record the correct cause text.
Example
To disable \ MyServer within 60 seconds, forcibly run the application to be closed, restart the system after shutdown, specify a user code, and specify the plan to shut down the system, then record the primary cause code 125 and secondary cause code 1. Type:
Shutdown-r-f-m \ MyServer-t 60-d up: 125: 1
