Please if someone could help me , I am knew to pweer shell. i how could i write a cript to shutdown a remote pc

errrr... while it's not a PowerShell thing.  You can shutdown any remote pc with shutdown.exe...

shutdown.exe /s /m \\targetpc /f
will shutdown targetpc forcefully, meaning close any apps open, and terminate any hung processes.

or if you prefer...
Shutdown.exe /I
will launch a gui. :)

I know about shutdown,exe . I  already have a vbscript to do the shutdown, I just  wanted to know if there was a way with powershell I can do it.

Thanks a lot , I will try it

give me a break... it's an .exe... does everything have to be either wmi or .net.

gc computers.txt | % {Invoke-Command {shutdown /t /m $_ /f }}

 let's not forget the BEST thing about posh.  Everything we ever learned is still applicable.

Having said that wmi is way better ;)

Try the Shutdown() method:

PS > (gwmi win32_operatingsystem  -computer computerName).Shutdown()
