wmic WMIC - Take Command-line Control over WMI
WMI 命令行 (WMIC) 實用工具為 Windows Management Instrumentation (WMI) 提供命令行接口。 WMIC 與現有 shell 和實用工具命令兼容， 自 Windows 10 版本 21H1 和 Windows 服務器的 21H1 半年頻道版本起棄用。
wmic csproduct list
通常情況下，可以通過命令行來獲取主板ID：
wmic csproduct get uuid
獲取CPU的標識符：
wmic cpu get processorid
獲取硬盤序列號：
wmic diskdrive get serialnumber
