Mastering Windows PowerShell Scripting - Second Edition

Creating instances

The arguments for Win32_Process.Create include a ProcessStartupInformation parameter. The ProcessStartupInformation is described by a WMI class, Win32_ProcessStartup.

There are no existing instances of Win32_ProcessStartup (Get-CimInstance), and the class does not have a Create method (or any other constructor).

New-CimInstance can be used to create a class:

$class = Get-CimClass Win32_ProcessStartup 
$startupInfo = New-CimInstance -CimClass $class -ClientOnly 

New-Object can also be used:

$class = Get-CimClass Win32_ProcessStartup 
$startupInfo = New-Object CimInstance $class 

Properties may be set on the created instance; the effect of each property is documented on the MSDN:
