简介

WMI简介：

WMI(Windows Management Instrumentation,Windows 管理规范)是一项核心的 Windows 管理技术；用户可以使用 WMI 管理本地和远程计算机。

WQL简介：

WQL就是WMI中的查询语言，WQL的全称是WMI Query Language，简称为WQL，翻译成中文好像可以成为Windows管理规范查询语言。熟悉SQL语言的朋友会感觉它和SQL非常相似。

WQL其实非常简单，它有如下特点：

1、每个WQL语句必须以SELECT开始；

2、SELECT后跟你需要查询的属性名(我刚才对应SQL将其称之为字段名了)，也可以像SQL一样，以*表示返回所有属性值；

3、FROM关键字；

4、你要查询的类的名字；

5、另外，如果你想精确查询结果还可以加上WHERE条件从句。比如某个类有Enable属性，你可以在查询的时候加上WHERE ENABLE=true，条件可以添加and or等关系操作。

如以下的都是正确的WQL语句：

Select * From Win32_LogicalDisk where drivetype=3    ’‘’‘查询所有硬盘分区

SELECT * FROM Win32_share  ’‘查询所有共享目录

SELECT * FROM Win32_NetworkAdapterConfiguration WHERE DHCPEnabled=TRUE

SELECT Description FROM Win32_Account WHERE Name='Administrator'

SELECT Freespace,DeviceID FROM Win32_LogicalDisk

在搜索框输入wbemtest即可查看WQL测试工具

1、环境准备

a、windows要开启Remote Registry与Windows Management Instrumentation服务

b、禁用放火墙

c、window2008系统注册表越狱(高版本的win)

需要修改regedit中HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}的权限，windows2008不再给Administrators完全控制权。

http://files.helgeklein.com/downloads/SetACL/current/SetACL%20(executable%20version).zip

set_wmi_reg_acl.cmd

SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn setowner -ownr "n:Administrators"

SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn ace -ace "n:Administrators;p:full"

以超级管理员身份执行这个cmd，就会把owner与完全控制权限授予Administrators组

注意这里需要把这个cmd命令和SetACL.exe copy到C:\Windows\System32文件夹
