PsShutdown has two features not found in the SHUTDOWN command:

• It will (by default) force the shutdown/restart of remote PCs so an interactive user cannot cancel the shutdown.
• Multiple remote PCs can be targeted at once ().

When launched for the first time, PsShutdown will create the regkey
HKCU\Software\Sysinternals\PsFile\EulaAccepted=0x01

Examples:

Reboot \\workstationF4T as part of an OS upgrade:

psshutdown \\workstationF4T -r -e p:2:3

Shutdown all the computers listed in a file (one per line):

psshutdown @c:\scripts\computers.txt -s
