How to create a new instance

  • Artigo

This topic shows how to create a new instance using the CreateInstance intrinsic method.

[!Important]
This example uses the Win32_Environment class, defined in the root\cimv2 namespace, because it implements the CreateInstance method.

 

New-EnvironmentVariable -Name <string> -UserName <string> -VariableValue <string>

The following sample CDXML shows how to markup a CDXML file to use the CreateInstance method to create a new instance of an object.
