从字面上看，在SE上有几十个答案和相关的问题，所有这些都在这样或那样的方式上存在缺陷，清楚地表明Windows没有提供可靠的内置控制台实用程序。所以，是时候推出你自己的了。

下面的C代码，基于检测程序是否以完全管理员权限运行，在Win2k+1中工作，在任何地方和所有情况下(UAC，域，可传递组…)-因为它在检查权限时与系统本身相同。它用消息(可以用开关使其静音)和退出代码表示结果。

它只需要编译一次，然后你可以复制。exe到处-它只依赖于kernel32.dll和advapi32.dll(我已经上传了一个副本)。

chkadmin.c:

#include <malloc.h>
#include <stdio.h>
#include <windows.h>
#pragma comment (lib,"Advapi32.lib")

int main(int argc, char** argv) {
    BOOL quiet = FALSE;
    DWORD cbSid = SECURITY_MAX_SID_SIZE;
    PSID pSid = _alloca(cbSid);
    BOOL isAdmin;

    if (argc > 1) {
        if (!strcmp(argv[1],"/q")) quiet=TRUE;
        else if (!strcmp(argv[1],"/?")) {fprintf(stderr,"Usage: %s [/q]\n",argv[0]);return 0;}
    }

    if (!CreateWellKnownSid(WinBuiltinAdministratorsSid,NULL,pSid,&cbSid)) {
        fprintf(stderr,"CreateWellKnownSid: error %d\n",GetLastError());exit(-1);}

    if (!CheckTokenMembership(NULL,pSid,&isAdmin)) {
        fprintf(stderr,"CheckTokenMembership: error %d\n",GetLastError());exit(-1);}

    if (!quiet) puts(isAdmin ? "Admin" : "Non-admin");
    return !isAdmin;
}

1MSDN声称api是XP+，但这是错误的。CheckTokenMembership是2k+，另一个甚至更老。最后一个链接还包含一种更复杂的方法，即使在NT中也可以工作。

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。

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

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 Call up just as the Administrator. Abbreviation can be done to the script and set:

echo Alternatively, a single run "Run as Administrator"
echo or in the Schedule tasks with highest privileges
pause > nul

还有两种方法——快速和向后兼容。

fltmc >nul 2>&1 && (
  echo has admin permissions
) || (
  echo has NOT admin permissions
)

fltmc命令在自XP以来的每个windows系统上都可用，所以这应该是相当可移植的。

在XP,8.1,7上测试的另一个真正快速的解决方案-有一个特定的变量=::，仅当控制台会话没有管理特权时才会显示。因为在它的名称中创建包含=的变量并不容易，这是一种相对可靠的检查管理权限的方法(它不调用外部可执行文件，所以它执行得很好)

setlocal enableDelayedExpansion
set "dv==::"
if defined !dv! ( 
   echo has NOT admin permissions
) else (
   echo has admin permissions
)

如果你想通过命令行直接使用，而不是从批处理文件，你可以使用:

set ^"|find "::"||echo has admin permissions
