VB中使用WMI获取系统硬件和软件有关信息

原帖地址：http://blog.csdn.net/ericbai/article/details/474308

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:

＆#39;用WMI,先工程-引用 Microsoft WMI Scripting V1.1 Library

获取显卡/声卡/内存/操作系统的信息

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
