WMI是英文Windows Management Instrumentation的简写，它的功能主要是：访问本地主机的一些信息和服务，可以管理远程计算机（当然你必须要拥有足够的权限），比如：重启，关机，关闭进程，创建进程等。
实例如下:

说明:
大家可能会发现一个规律,实际上WMI对信息的提取都是使用了WIN32_类库名这样的规律,下列表格就是微软的操作系统各种硬件类的描述
其它WMI管理的类的信息在
/library/default.asp?url=/library/en-us/wmisdk/wmi/accessing_hardware_and_software_through_wmi.asp
可以找到,其中也还有部分示例代码
