you will have to check the documentatoin of shutdown for the ME version. This aside, you can this vbscript too, however you should check whether ME has WSH/cscript (i think it has, but old version).
Set colOperatingSystems = GetObject("winmgmts:{(Shutdown)}").ExecQuery("Select * from Win32_OperatingSystem")
For Each objOperatingSystem in colOperatingSystems
objOperatingSystem.Win32Shutdown(1)
Next
