WMI (Windows Management Instrumentation) 子產品可用于擷取 Windows 内部資訊，在使用Python擷取Windows系統上的相關的資訊可以使用WMI接口來擷取，
什麼是wmi？
WMI是一項核心的Windows管理技術，WMI作為一種規範和基礎結構，通過它可以通路、配置、管理和監視幾乎所有的Windows資源，比如使用者可以在遠端計算機器上啟動一個程序；設定一個在特定日期和時間運作的程序；遠端啟動計算機；獲得本地或遠端計算機的已安裝程式清單；查詢本地或遠端計算機的Windows事件日志等等。
該子產品需要 win32com 的支援，環境安裝如下，
pip install wmi
pip install pypiwin32 測試安裝結果
>>> import win32con
>>> import wmi 導入子產品沒有報錯，證明安裝完成
wmi.WMI() 用于生成wmi執行個體 >>> wmi.WMI()
<_wmi_namespace: <COMObject winmgmts:>> 查詢CPU資訊
用于擷取CPU處理器資訊對象，并存以清單形式
wmi.Win32_Processor() 方法
傳回參數: processorList
processorList: list類型，list中每個元素均為一個含cpu資訊的object對象
