在VB中使用WMI获取系统硬件和软件有关信息
http://dev.csdn.net/develop/article/23/23371.shtm
简介:
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:
'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

操作系统信息
Private Sub Command1_Click()

For Each obj In wmiObjSet
MsgBox "你当前使用的系统是 " & obj.Caption

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

可以找到,其中也还有部分示例代码
