SHUTDOWN

Shuts down, reboots, hibernates, or logs off the specified system.

SHUTDOWN [/I | /L | /S [/HYBRID] | /SG | /R [/O] | /G | /A | /P | /H] [/SOFT] [/FW] [/E] [/F] [/M \\remote_system] [/T time] [/C "comment"] [/D [P:|U:]xx:yy]

Where:

• /I - Displays the graphical user interface (GUI), through which you can set the local or remote system shutdown or reboot. Other options will be ignored.
• /L - Logs the current user off the local system. The /M or /D options cannot be specified.
• /S - Shuts down the local system or the remote system specified with /M.
• /SG - Shuts down the local system or the remote system specified with /M. If automatic login on restart is enabled, automatically logs in (prompts for password) based on the last interactive user. After logging in, all registered applications are restored.
• /R - Restarts the local system or the remote system specified with /M.
• /G - Restarts the local system or the remote system specified with /M. If automatic login on restart is enabled, automatically logs in (prompts for password) based on the last interactive user. After logging in, all registered applications are restored.
• /A - Aborts a system shutdown if executed during the countdown period (before the shutdown is actually initiated). When used with the /FW option, clears pending boots in the firmware.
• /P - Shuts down the local system or the remote system specified with /M, without waiting for a countdown period and without displaying a warning dialog. No options may be specified except /F and /D.
• /H - Hibernates the local system. No options can be specified except /F.
• /HYBRID - Shuts down the system and prepares it for fast boot.
• /O - Goes to the advanced boot options menu before rebooting your system.
• /SOFT - Allows processes and applications to close without being force-quit.
• /FW - When used with a shutdown or restart option, specifies that the next boot will be performed in the firmware user interface. When used with /A, clears pending boot in the firmware.
• /E - Specifies the reason for the unexpected shutdown in the Shutdown Event Tracker.
• /F - Force closes running applications without warning.
• /M \\remote_system - Specifies the remote system to shut down or restart. Cannot be used with the /L (log off) or /H (hibernate) options.
• /T tempo - Specifies the time in seconds to count down before shutdown or restart. You can specify a time in the range 0-315359999 (that is, up to 3650 days minus 1 second, or about 10 years). The default is 30 seconds. If time is greater than 0, it implies the /F option.
• /C "comment" - Specifies the comment or message to display regarding the reason for the shutdown or restart, up to 512 characters.
• /D [P:|U:]xx:yy - Specifies the reason for shutting down or restarting the specified system. P: specifies that the shutdown or restart is planned, while U: specifies that the reason is user-defined. Without either P: or U:, the shutdown or restart is unplanned. xx:yy are two numbers separated by a colon :, where the first xx describes the primary reason (0-255) while yy describes the secondary reason (0-65535). The following is a list of possible values for xx:yy with their meanings (values may change depending on the system):

  Code	Meaning
  0:0	Other
  0:5	Error: the system is not responding
  1:1	Hardware: maintenance
  1:2	Hardware: installation
  2:2	Operating system: recovery
  2:4	Operating system: reconfiguration
  2:16	Operating system: service pack
  2:17	Operating system: quick fix
  2:18	Operating system: quick security fix
  4:1	Application: maintenance
  4:2	Application: installation
  4:5	Application: not responding
  4:6	Application: unstable
  5:15	System error: fatal error
  5:19	Security issue
  5:20	Loss of network connectivity
  6:11	Power failure: cable disconnected
  6:12	Power failure: environment
  7:0	Previous version API shutdown

Examples:

1. Shut down your system by setting a 100-second countdown and displaying a nice greeting:

shutdown /s /t 100 /c "Hello!"

 

2. If executed before the 100 seconds in the previous example have passed, it stops the shutdown:

shutdown /a
