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
