WMI First using sample：Method 2：To connect to WMI and retrieve an object using a moniker --- Creating a Registry Key Using VBScript

WMI monikers can consist of three parts: one mandatory component and two optional components. The mandatory component is the "winmgmts:" prefix.

All WMI monikers must begin with "winmgmts:" as shown here:

Set objSWbemServices = GetObject("winmgmts:")

After you have obtained a reference to SWbemServices, you can then invoke one of the object methods as shown here:

Set colSWbemObjectSet = objSWbemServices.InstancesOf("Win32_LogicalDisk")

Step 1、write the vb script as following, and save it as "NEW_RegistryKey.vbs"

WMI First using sample：Method 1： To connect to WMI using SWbemLocator--- Creating a Registry Key Using VBScript

You can use the methods of the SWbemLocator object to obtain an SWbemServices object that represents a connection to a namespace on either a local computer or a remote host computer. You can then use the methods of the SWbemServices object to access WMI.

You can use the methods of an SWbemServices object to perform operations against a namespace on either a local host or a remote host. This object cannot be created by the VBScript CreateObject call.

Step 1、write the vb script as following, and save it as "NEW_RegistryKey.vbs"

Windows WMI的架構簡介

Windows Management Instrumentation (WMI)是management data和操作Windows-based (OS)operating systems的infrastructure。 可以寫WMI scripts或applications來自動化管理remote computers，但是WMI也支援operating system的其他部分和其他產品，如System Center Operations Manager、早期的Microsoft Operations Manager (MOM)、Windows Remote Management (WinRM)。

下圖顯示WMI infrastructure、 WMI providers and managed objects的關係，並且顯示WMI infrastructure、WMI consumers之間的關係。

在 WMI infrastructure，WMI service (Winmgmt，operating system component)作為 management applications和WMI data providers的mediator ，he WMI repository 是一個WMI-related static data 的storage area。

當management application或 script 呼叫連接到一個WMI namespace，WMI service 開始執行。 WMI service經由COM interface 和management applications互動。
