That comment is utterly uninformed. If you want to run a script simultaneously on a number of hosts, you use the Invoke-Command cmdlet (or it's alias icm ). If you want to stop a process, you use Stop-Process (or it's alias

Silly me, I assumed that the executable path was the requirement. My bad. If you need to find a process just by it's name, it is even simpler: Just indicate the process name (possibly with wildcards) to Get-Process (alias ps ): ps Not
