Shuts down, restarts, or logs off the system.

Shutdown, Code



A combination of shutdown codes listed below.


The shutdown code is a combination of the following values:

Logoff 0
Shutdown 1
Reboot 2
Force 4
Power down 8
Suspend/Hibernate See DllCall example at the bottom of this page.
Turn monitor off See PostMessage examples.

Add the required values together. For example, to shutdown and power down the code would be 9 (shutdown + power down = 1 + 8 = 9). Alternatively, an expression such as 1+8 can be specified.

The "Force" value (4) forces all open applications to close. It should only be used in an emergency because it may cause any open applications to lose data.

The "Power down" value shuts down the system and turns off the power.

On a related note, a script can detect when the system is shutting down or the user is logging off via OnExit.


Run, ExitApp, OnExit


; Force a reboot (reboot + force = 2 + 4 = 6):
Shutdown, 6

; Parameter #2: Pass 1 instead of 0 to suspend immediately rather than asking each application for permission.
; Parameter #3: Pass 1 instead of 0 to disable all wake events.
