Invoke WmiMethod - PowerShell


Invoke-WmiMethod invokes methods on Windows Management Instrumentation (WMI) classes to perform various operations on remote or local computers. It enables you to retrieve and modify data, configure settings, and control system components using WMI interfaces.


Invoke-WmiMethod [-Class] <string> [-ComputerName] <string[]> [-Method] <string> [-Parameters] <psobject> [-Namespace] <string> [-Provider] <string> [-UseAmendedNamespace]


-Class: Specifies the WMI class that contains the method to be invoked.

-ComputerName: (Optional) Specifies the name of the remote computer where the method will be invoked. Multiple computer names can be provided as an array.

-Method: Specifies the name of the method to be invoked.

-Parameters: (Optional) Specifies a hashtable of parameters to be passed to the method.

-Namespace: Specifies the WMI namespace where the class is located.

-Provider: Specifies the WMI provider to use when invoking the method. By default, the MSFT_WMIProvider provider is used.

-UseAmendedNamespace: (Optional) If specified, uses the amended namespace path for the WMI class instead of the canonical namespace path. This option should be used when working with classes that have been renamed or moved to a different namespace.
