簡(jiǎn)介

WMI簡(jiǎn)介：

WMI(Windows Management Instrumentation,Windows 管理規(guī)范)是一項(xiàng)核心的 Windows 管理技術(shù)；用戶可以使用 WMI 管理本地和遠(yuǎn)程計(jì)算機(jī)。

WQL簡(jiǎn)介：

WQL就是WMI中的查詢語(yǔ)言，WQL的全稱是WMI Query Language，簡(jiǎn)稱為WQL，翻譯成中文好像可以成為Windows管理規(guī)范查詢語(yǔ)言。熟悉SQL語(yǔ)言的朋友會(huì)感覺(jué)它和SQL非常相似。

WQL其實(shí)非常簡(jiǎn)單，它有如下特點(diǎn)：

1、每個(gè)WQL語(yǔ)句必須以SELECT開(kāi)始；

2、SELECT后跟你需要查詢的屬性名(我剛才對(duì)應(yīng)SQL將其稱之為字段名了)，也可以像SQL一樣，以*表示返回所有屬性值；

3、FROM關(guān)鍵字；

4、你要查詢的類的名字；

5、另外，如果你想精確查詢結(jié)果還可以加上WHERE條件從句。比如某個(gè)類有Enable屬性，你可以在查詢的時(shí)候加上WHERE ENABLE=true，條件可以添加and or等關(guān)系操作。

如以下的都是正確的WQL語(yǔ)句：

Select * From Win32_LogicalDisk where drivetype=3 ???’‘’‘查詢所有硬盤分區(qū)

SELECT * FROM Win32_share ?’‘查詢所有共享目錄

SELECT * FROM Win32_NetworkAdapterConfiguration WHERE DHCPEnabled=TRUE

SELECT Description FROM Win32_Account WHERE Name='Administrator'

SELECT Freespace,DeviceID FROM Win32_LogicalDisk

在搜索框輸入wbemtest即可查看WQL測(cè)試工具

1、環(huán)境準(zhǔn)備

a、windows要開(kāi)啟Remote Registry與Windows Management Instrumentation服務(wù)

b、禁用放火墻

c、window2008系統(tǒng)注冊(cè)表越獄(高版本的win)

需要修改regedit中HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}的權(quán)限，windows2008不再給Administrators完全控制權(quán)。

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"

以超級(jí)管理員身份執(zhí)行這個(gè)cmd，就會(huì)把owner與完全控制權(quán)限授予Administrators組

注意這里需要把這個(gè)cmd命令和SetACL.exe copy到C:\Windows\System32文件夾

2、程序代碼
