如何检查当前批处理脚本是否具有管理权限?

我知道如何使它调用自己与runas,但不知道如何检查管理权限。我所见过的唯一解决方案是粗糙的黑客工作或使用外部程序。好吧,其实我不在乎这是不是一份苦差事,只要它能在Windows XP或更新版本上运行就行。

我有两种检查特权访问的方法,这两种方法都非常可靠,而且几乎在每个windows版本上都非常可移植。

1. 方法

set guid=%random%%random%-%random%-%random%-%random%-%random%%random%%random%

mkdir %WINDIR%\%guid%>nul 2>&1
rmdir %WINDIR%\%guid%>nul 2>&1

IF %ERRORLEVEL%==0 (
    ECHO PRIVILEGED!
) ELSE (
    ECHO NOT PRIVILEGED!
)

这是最可靠的方法之一,因为它很简单,而且这个非常原始的命令的行为不太可能改变。这不是其他内置CLI工具的情况,比如可以通过管理/网络策略禁用的net session,或者像fsutils这样在Windows 10上改变输出的命令。

*适用于XP及以后

2. 方法

REG ADD HKLM /F>nul 2>&1

IF %ERRORLEVEL%==0 (
    ECHO PRIVILEGED!
) ELSE (
    ECHO NOT PRIVILEGED!
)

Sometimes you don't like the idea of touching the user disk, even if it is as inoffensive as using fsutils or creating a empty folder, is it unprovable but it can result in a catastrophic failure if something goes wrong. In this scenario you can just check the registry for privileges. For this you can try to create a key on HKEY_LOCAL_MACHINE using default permissions you'll get Access Denied and the ERRORLEVEL == 1, but if you run as Admin, it will print "command executed successfully" and ERRORLEVEL == 0. Since the key already exists it have no effect on the registry. This is probably the fastest way, and the REG is there for a long time. * It's not avaliable on pre NT (Win 9X).

*适用于XP及以后


工作示例

清除临时文件夹的脚本

@echo off :main echo. echo. Clear Temp Files script echo. call :requirePrivilegies rem Do something that require privilegies echo. del %temp%\*.* echo. End! pause>nul goto :eof :requirePrivilegies set guid=%random%%random%-%random%-%random%-%random%-%random%%random%%random% mkdir %WINDIR%\%guid%>nul 2>&1 rmdir %WINDIR%\%guid%>nul 2>&1 IF NOT %ERRORLEVEL%==0 ( echo ########## ERROR: ADMINISTRATOR PRIVILEGES REQUIRED ########### echo # This script must be run as administrator to work properly! # echo # Right click on the script and select "Run As Administrator" # echo ############################################################### pause>nul exit ) goto :eof

其他回答

下面尝试在Windows目录中创建一个文件。如果成功,它将移除它。

copy /b/y NUL %WINDIR%\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1
if errorlevel 1 goto:nonadmin
del %WINDIR%\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1
:admin
rem here you are administrator
goto:eof
:nonadmin
rem here you are not administrator
goto:eof

请注意,06CF2EB6-94E6-4a60-91D8-AB945AE8CF38是今天生成的GUID,假定它与现有文件名不太可能冲突。

whoami /groups | find "S-1-16-12288" > nul
if not errorlevel 1 (
  echo ...  connected as admin
)

whoami /groups在一种情况下不起作用。如果你已经完全关闭了UAC(不仅仅是关闭了通知),并且你从一个管理员提示开始,然后发出:

runas /trustlevel:0x20000 cmd

你将运行非提升,但发出:

whoami /groups

会说你升职了。这是错误的。这就是为什么它是错误的:

当在这种状态下运行时,如果IsUserAdmin (https://msdn.microsoft.com/en-us/library/windows/desktop/aa376389(v=vs.85).aspx)返回FALSE并且UAC完全禁用,并且GetTokenInformation返回TokenElevationTypeDefault (http://blogs.msdn.com/b/cjacks/archive/2006/10/24/modifying-the-mandatory-integrity-level-for-a-securable-object-in-windows-vista.aspx),那么进程不是在运行elevated,但是whoami /groups声称它是。

实际上,从批处理文件中做到这一点的最好方法是:

net session >nul 2>nul
net session >nul 2>nul
echo %errorlevel%

你应该做两次net session,因为如果有人事先做了at,你会得到错误的信息。

另一种方法。

FSUTIL | findstr /I "volume" > nul&if not errorlevel 1  goto Administrator_OK

cls
echo *******************************************************

echo.
echo.
echo Call up just as the Administrator. Abbreviation can be done to the script and set:
echo.
echo      Shortcut ^> Advanced ^> Run as Administrator
echo.
echo.
echo Alternatively, a single run "Run as Administrator"
echo or in the Schedule tasks with highest privileges
pause > nul
goto:eof
:Administrator_OK
