public class Sample
{
    public static void Main()
    {

        ManagementClass envClass =
            new ManagementClass("Win32_Environment");
        ManagementObject newInstance =
            envClass.CreateInstance();
        newInstance["Name"] = "testEnvironmentVariable";
        newInstance["VariableValue"] = "testValue";
        newInstance["UserName"] = "<SYSTEM>";
        newInstance.Put(); //to commit the new instance.
    }
}

Imports System.Management


Class Sample
    Public Overloads Shared Function _
        Main(ByVal args() As String) As Integer

        Dim envClass As New ManagementClass( _
            "Win32_Environment")
        Dim newInstance As ManagementObject

        newInstance = envClass.CreateInstance()
        newInstance("Name") = "testEnvironmentVariable"
        newInstance("VariableValue") = "testValue"
        newInstance("UserName") = "<SYSTEM>"
        newInstance.Put()  'to commit the new instance.

    End Function
End Class

Remarks

Note that the new instance is not committed until the Put() method is called. Before committing it, the key properties must be specified.
