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

PowerShell有人吗?

param (
    [string]$Role = "Administrators"
)

#check for local role

$identity  = New-Object Security.Principal.WindowsIdentity($env:UserName)
$principal = New-Object Security.Principal.WindowsPrincipal($identity)

Write-Host "IsInRole('$Role'): " $principal.IsInRole($Role)

#enumerate AD roles and lookup

$groups = $identity::GetCurrent().Groups
foreach ($group in $groups) {
    $trans = $group.Translate([Security.Principal.NTAccount]);
    if ($trans.Value -eq $Role) {
       Write-Host "User is in '$Role' role"
    }
}

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

编辑:版权已指出这是不可靠的。使用UAC批准读访问将允许dir成功。我有更多的脚本来提供另一种可能性，但它不是只读的。

reg query "HKLM\SOFTWARE\Foo" >NUL 2>NUL && goto :error_key_exists
reg add "HKLM\SOFTWARE\Foo" /f >NUL 2>NUL || goto :error_not_admin
reg delete "HKLM\SOFTWARE\Foo" /f >NUL 2>NUL || goto :error_failed_delete
goto :success

:error_failed_delete
  echo Error unable to delete test key
  exit /b 3
:error_key_exists
  echo Error test key exists
  exit /b 2
:error_not_admin
  echo Not admin
  exit /b 1
:success
  echo Am admin

旧答案如下

警告:不可靠

根据and31415提出的其他一些很好的答案和观点，我发现我是以下人的粉丝:

dir "%SystemRoot%\System32\config\DRIVERS" 2>nul >nul || echo Not Admin

依赖性少，速度快。

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。
