使用CMD脚本检查管理权限的最干净的方法，我发现，是这样的:

@echo off

REM  Calling verify with no args just checks the verify flag,
REM   we use this for its side effect of setting errorlevel to zero
verify >nul

REM  Attempt to read a particular system directory - the DIR
REM   command will fail with a nonzero errorlevel if the directory is
REM   unreadable by the current process.  The DACL on the
REM   c:\windows\system32\config\systemprofile directory, by default,
REM   only permits SYSTEM and Administrators.
dir %windir%\system32\config\systemprofile >nul 2>nul

REM  Use IF ERRORLEVEL or %errorlevel% to check the result
if not errorlevel 1 echo has Admin privs
if     errorlevel 1 echo has only User privs

这个方法只使用CMD.exe内置程序，所以它应该非常快。它还检查流程的实际功能，而不是检查sid或组成员关系，因此测试有效的权限。这可以追溯到Windows 2003和XP。普通用户进程或非提升进程目录探测失败，而Admin进程或提升进程成功。

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

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

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。

替代方案:使用专门为此目的设计的外部实用程序，例如IsAdmin.exe(不受限制的免费软件)。

退出代码:

0 -当前用户不是Administrators组的成员

1 -管理员的当前用户成员和运行提升

2 -管理员的当前用户成员，但未运行提升
