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

另一种方法。

REM    # # # #      CHECKING OR IS STARTED AS ADMINISTRATOR     # # # # #

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

cls
echo *******************************************************
echo ***    R U N    A S    A D M I N I S T R A T O R    ***
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

REM Some next lines code ...

@echo off
:start
set randname=%random%%random%%random%%random%%random%
md \windows\%randname% 2>nul
if %errorlevel%==0 (echo You're elevated!!!
goto end)
if %errorlevel%==1 (echo You're not elevated :(:(
goto end)
goto start
:end
rd \windows\%randname% 2>nul
pause >nul

我将逐行解释代码:

@echo off

如果没有这个选项，用户会对超过一行的代码感到厌烦。

:start

指向程序开始的位置。

set randname=%random%%random%%random%%random%%random%

设置要创建的目录的文件名。

md \windows\%randname% 2>nul

在<DL>:\Windows上创建目录(将<DL>替换为驱动器号)。

if %errorlevel%==0 (echo You're elevated!!!
goto end)

如果ERRORLEVEL环境变量为零，则返回成功消息。 读到最后(不要再继续了)。

if %errorlevel%==1 (echo You're not elevated :(:(
goto end)

如果ERRORLEVEL为1，回显失败消息并返回结束。

goto start

如果文件名已经存在，则重新创建文件夹(否则goto end命令将不让该文件夹运行)。

:end

指定结束点

rd \windows\%randname% 2>nul

删除已创建的目录。

pause >nul

暂停以便用户可以看到消息。

注意:>nul和2>nul是对这些命令的输出进行过滤。

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

>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"&&(
 echo admin...
)

可选择的解决方案:

@echo off
pushd %SystemRoot%
openfiles.exe 1>nul 2>&1
if not %errorlevel% equ 0 (
    Echo here you are not administrator!
) else (
    Echo here you are administrator!
)
popd
Pause
