WSH [1] Set OpSysSet = GetObject("winmgmts:{(Shutdown)}//./root/cimv2").ExecQuery("select * from Win32_OperatingSystem where Primary=true")
for each OpSys in OpSysSet
[4]     OpSys.Reboot( )
[5] next
Reboot Requires WMI.
Remove [line numbers].
(by Alex K. Angelopoulos)
WSH Replace line 4 in the script above with this one:
[4]    OpSys.Shutdown( )
to shut down the PC instead of rebooting it.
Shutdown But no poweroff.
See my WSH page for examples on how to reboot or shut down remote computers too.
WSH [1] Const EWX_LOGOFF   = 0
Set wmi = GetObject("winmgmts:{(Shutdown)}")
[4] Set objSet = wmi.InstancesOf("Win32_OperatingSystem")
For Each obj in objSet
[7]     Set os = obj
[8]     Exit For
[9] Next
os.Win32Shutdown EWX_LOGOFF
Logoff Requires WMI.
Remove [line numbers].
(Posted by Michael Harris on microsoft.public.scripting.vbscript)
My Logoff.vbs combines this code with that of the reboot and shutdown commands, and allows logoff of remote computers as well.
WSH Set objShell = CreateObject( "Shell.Application" )
Open the Shutdown dialog Based on the Advanced Stuff listing on
OS/2 START /PM SHUTDOWN && EXIT Shutdown Will still stop and ask for confirmation if a non-PM application is active
OS/2 SETBOOT /B Reboot Unconditional shutdown & reboot from default Boot Manager entry.
(Mailed by Rick Curry)
OS/2 SETBOOT /IBD:C: Reboot Unconditional shutdown & reboot from C: drive
OS/2 SETBOOT /IBA:nonsense Shutdown Unconditional shutdown & failing reboot.
Needs Boot Manager installed.
Will reboot, no questions asked, and then stop if nonsense is an invalid Boot Manager menu entry (which, in this case, is exactly what we want).
OS/2 LOGOFF Logoff Both LAN Server client and Peer

Windows NT also has a RUNONCE.EXE, but I am not sure what its purpose is — RUNONCE.EXE -q does not shut down NT.

FoolishIT's ShutdownUnless is a safe way to schedule server reboots, aborting the reboot if any client connections are active.

Jorgen Bosman's PowerOff for all Windows (32-bits) versions can power off, shutdown or reboot your PC, log you off, lock your workstation, go to standby or hibernation mode and even wake up another PC.
All actions can be done locally or on a remote PC (if it is running PowerOff).
The actions can be performed immediately or scheduled, by using its built-in scheduler.
This tool can be used both as a GUI or as a command line tool.

Gibson Research's Wizmo is a collection of tools integrated in a single package.
Among its functions are shutdown, reboot, hibernate and logoff.

SysInternals' PSSHUTDOWN can perform logoffs, poweroffs, shutdowns and reboots on both local and remote Windows NT 4/2000/XP systems.
A must-have for mixed Windows environments.

NirCmd is a small command-line utility that allows you to do some useful tasks without displaying any user interface.
By running NirCmd with simple command-line option, you can restart windows or shut down the computer, write and delete values and keys in the Registry, write values into INI file, dial to your internet account or connect to a VPN network, create shortcut to a file, change the created/modified date of a file, change your display settings, turn off your monitor, open the door of your CD-ROM drive, and more...

For Windows XP (and later) use the native POWERCFG command to configure Standby and Hibernate (and more).
