Access WMI Objects from PowerShell
Note that you can also access and manipulate WMI objects using PowerShell. PowerShell helps administrators to access the richness and power of WMI in several ways:
  • The Get-WMIObject cmdlet enables you to get any WMI object that is represented in the CIM. You can also use Get-WMIObject to list out the WMI classes present to aid in discovery.
  • The [wmi], [wmiclass] and [wmisearcher] type accelerators that simplfy accessing WMI objects.
  • Default formatting for core objects to aid in discovery.
Some of the WMI classes here have been decorated with samples using PowerShell.
