SolarWinds WMI Monitor Download 100% Free Tool Take the guesswork out of which WMI counters to use when scripting the operating system, Active Directory, or Exchange Server. Fortunately, SolarWinds have created a Free WMI Monitor for PowerShell so that you can discover these gems of performance information, and thus improve your PowerShell scripts. Windows Management Instrumentation (WMI) is one of the hidden treasures of Microsoft’s operating systems. Guy Recommends: Free WMI Monitor for PowerShell (FREE TOOL) Note 3: Please don’t use Stop-Process unless you understand what you are doing, for instance, you make a ‘walk-though’ of stopping the process with task manager. Stop-Process 5132, 5075, 5072 -ErrorAction Silentl圜ontinue Then substitute your PIDs for 5132, 5075, 5072 in my script below. Zapping processes is a classic job for Silentl圜ontinue … provided you know what you’re doing! If you would like to try this for real, then launch Task Manager and note the PID (process ID) of one real and two fictitious processes. “Cannot find a process with the process identifier 5132” The problem arises when the first process does not exist, consequently the script comes to a halt prematurely. Scenario you create a PowerShell script which will kill several processes. I made this deliberate mistake so as to create the error message.
Note 2: The actual name of this service is Print Spooler (not Print er). Action Point remove -ErrorAction Silentl圜ontinue from the above script. Note 1: While this example shows -ErrorAction, you must decide if it’s better than the built-in message ObjectNotFound.
$Service = Get-Service -display $SrvName -ErrorAction Silentl圜ontinue # PowerShell -ErrorAction Silentl圜ontinue example ErrorAction Example: Check If a Service Has Been Installed

If a PowerShell script halts, or a portion of the code does not work, what action do you want the error to trigger? One popular solution is to tell the script to silently continue.
