WSH Replace line 4 in the script above with this one:

to shut down the PC instead of rebooting it.
Shutdown But no poweroff.

My Logoff.vbs combines this code with that of the reboot and shutdown commands, and allows logoff of remote computers as well.
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

Thanks for Alec Soroudi for pointing out this information.
Windows NT also has a RUNONCE.EXE, but I am not sure what its purpose is -- RUNONCE.EXE -q does not shut down NT.
5 Requires Microsoft's DEVCON utility

 

Use Andrej Budja's XP Shutdown replacement if you want to poweroff your computer from the command line.

Didier Cassereau's Logoff tool for Windows NT can logoff, shutdown, reboot or power off from the command line.

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.

And last but not least SysInternals.com's PSSHUTDOWN can perform logoffs, poweroffs, shutdowns and reboots on both local and remote Windows NT 4/2000/XP systems. Absolutely recommended.
