我最近需要一个用户友好的方法，我根据这里和其他地方的贡献者的宝贵见解想出了这个方法。只需将这一行放在.bat脚本的顶部。欢迎您的反馈。

@pushd %~dp0 & fltmc | find "." && (powershell start '%~f0' ' %*' -verb runas 2>nul && exit /b)

无畏：

@pushd %~dp0 ensures a consistant working directory relative to this batch file; supports UNC paths fltmc a native windows command that outputs an error if run unelevated | find "." makes the error prettier, and causes nothing to output when elevated && ( if we successfully got an error because we're not elevated, do this... powershell start invoke PowerShell and call the Start-Process cmdlet (start is an alias) '%~f0' pass in the full path and name of this .bat file. Single quotes allow spaces in the path/file name ' %*' pass in any and all arguments to this .bat file. Funky quoting and escape sequences probably won't work, but simple quoted strings should. The leading space is needed to prevent breaking things if no arguments are present -verb runas don't just start this process...RunAs Administrator! 2>nul discard PowerShell's unsightly error output if the UAC prompt is canceled/ignored. && if we successfully invoked ourself with PowerShell, then... NOTE: in the event we don't obtain elevation (user cancels UAC), then && allows the .bat to continue running without elevation, such that any commands that require it will fail but others will work just fine. If you want the script to simply exit instead of running unelevated, make this a single ampersand: & exit /b) exits the initial .bat processing, because we don't need it anymore; we have a new elevated process currently running our .bat. Adding /b allows cmd.exe to remain open if the .bat was started from the command line...it has no effect if the .bat was double-clicked

如果你不关心参数，那么这里有一个紧凑的UAC提示脚本，只有一行长。它不会传递参数，因为没有万无一失的方法来处理所有可能的有毒字符组合。

net sess>nul 2>&1||(echo(CreateObject("Shell.Application"^).ShellExecute"%~0",,,"RunAs",1:CreateObject("Scripting.FileSystemObject"^).DeleteFile(wsh.ScriptFullName^)>"%temp%\%~nx0.vbs"&start wscript.exe "%temp%\%~nx0.vbs"&exit)

在批处理文件的@echo off下面粘贴这一行。

解释

net sess>nul 2>&1部分是用来检查海拔高度的。Net sess只是Net session的简写，Net session是一个命令，当脚本没有提升权限时返回错误代码。我从这个SO答案中得到了这个想法。这里的大多数答案都是网络文件，尽管它的工作原理是一样的。该命令快速且在许多系统上兼容。

然后使用||操作符检查错误级别。如果检查成功，它将创建并执行一个WScript，该WScript在删除自己之前重新运行原始批处理文件，但具有更高的权限。

选择

WScript文件是快速可靠的最佳方法，尽管它使用临时文件。这里有一些其他的变化和他们的缺点/优点。

PowerShell

net sess>nul 2>&1||(powershell saps '%0'-Verb RunAs&exit)

优点:

很短的。 没有临时文件。

缺点:

缓慢。PowerShell启动可能很慢。 当用户拒绝UAC提示时，喷射红色文本。PowerShell命令可以封装在try{…}catch{}来防止这种情况。

Mshta WSH脚本

net sess>nul 2>&1||(start mshta.exe vbscript:code(close(Execute("CreateObject(""Shell.Application"").ShellExecute""%~0"",,,""RunAs"",1"^)^)^)&exit)

优点:

快。 没有临时文件。

缺点:

不可靠。一些Windows 10系统会阻止脚本运行，因为Windows防御器会拦截它作为一个潜在的木马。

正如jcoder和Matt提到的，PowerShell使它变得很容易，甚至可以在不创建新脚本的情况下嵌入到批处理脚本中。

我修改了马特的剧本:

:: Check privileges 
net file 1>NUL 2>NUL
if not '%errorlevel%' == '0' (
    powershell Start-Process -FilePath "%0" -ArgumentList "%cd%" -verb runas >NUL 2>&1
    exit /b
)

:: Change directory with passed argument. Processes started with
:: "runas" start with forced C:\Windows\System32 workdir
cd /d %1

:: Actual work

一行批处理用户提升(带参数)

以下是我对这个古老的批量用户提升问题的单行版本，这个问题在今天仍然是相关的。 只需将代码添加到批处理脚本的顶部，就可以开始了。

沉默

这个版本不会输出任何东西，也不会在出错时暂停执行。

@setlocal disabledelayedexpansion enableextensions
@echo off

:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" ((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul)))& exit /b)

详细的

详细版本，告诉用户正在请求管理权限，并在退出前暂停错误。

@setlocal disabledelayedexpansion enableextensions
@echo off

:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" (echo Requesting administrator privileges...&((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul))) else (echo This script requires administrator privileges.& pause))& exit /b)

echo Has admin permissions
echo Working dir: "%cd%"
echo Script dir: "%~dp0"
echo Script path: "%~f0"
echo Args: %*

pause

操作方法

Uses fltmc to check for administrator privileges. (system component, included in Windows 2000+) If user already has administrator privileges, continues operation normally. If not, spawns an elevated version of itself using either: powershell (optional Windows feature, included in Windows 7+ by default, can be uninstalled/otherwise not available, can be installed on Windows XP/Vista) mshta (system component, included in Windows 2000+) If fails to acquire elevation, stops execution (instead of looping endlessly).

这个解决方案与其他解决方案的区别是什么?

实际上，解决这个问题的方法有数百种，但我迄今为止发现的所有方法都有其缺点，这是解决其中大多数问题的尝试。

Compatibility. Using fltmc as the means of checking for privileges and either powershell or mshta for elevation works with every Windows version since 2000 and should cover most system configurations. Does not write any extra files. Preserves current working directory. Most of the solutions found conflate "script directory" with "working directory" which are totally different concepts. If you want to use "script directory" instead, replace %cd% with %~dp0. Some people advocate using pushd "%~dp0" instead so paths inside networked UNC paths like "\\SOMEONES-PC\share" will work but that will also automagically map that location to a drive letter (like Y:) which might or might not be what you want. Stops if unable to acquire elevation. This can happen because of several reasons, like user clicking "No" on the UAC prompt, UAC being disabled, group policy settings, etc. Many other solutions enter an endless loop on this point, spawning millions of command prompts until the heat death of the universe. Supports (most of) command-line arguments and weird paths. Stuff like ampersands &, percent signs %, carets ^ and mismatching amount of quotes """'. You still definitely CAN break this by passing a sufficiently weird combinations of those, but that is an inherent flaw of Windows' batch processing and cannot really be worked around to always work with any combination. Most typical use-cases should be covered though and arguments work as they would without the elevation script.

已知的问题

If you enter a command-line argument that has a mismatched amount of double-quotes (i.e. not divisible by 2), an extra space and a caret ^ will be added as a last argument. For example "arg1" arg2" """" "arg3" will become "arg1" arg2" """" "arg3" ^. If that matters for your script, you can add logic to fix it, f.ex. check if _ELEV=1 (meaning that elevation was required) and then check if the last character of argument list is ^ and/or amount of quotes is mismatched and remove the misbehaving caret.

日志输出到文件的示例脚本

您不能轻易地使用>进行标准输出日志记录，因为在提升时将生成一个新的cmd窗口并切换执行上下文。

你可以通过传递越来越奇怪的转义字符组合来实现它，比如raise .bat testarg ^^^> test.txt，但你需要让它总是生成新的cmd窗口，或者添加逻辑来去掉插入符号，所有这些都增加了复杂性，在许多情况下它仍然会中断。

最好和最简单的方法是在批处理脚本中添加日志记录，而不是尝试从命令行重定向。这样你就不用再头疼了。

这里有一个例子，你可以很容易地实现你的脚本日志:

@setlocal disabledelayedexpansion enableextensions
@echo off

:: Admin check
fltmc >nul 2>nul || set _=^"set _ELEV=1^& cd /d """%cd%"""^& "%~f0" %* ^"&&((if "%_ELEV%"=="" (echo Requesting administrator privileges...&((powershell -nop -c start cmd -args '/d/x/s/v:off/r',$env:_ -verb runas >nul 2>nul) || (mshta vbscript:execute^("createobject(""shell.application"").shellexecute(""cmd"",""/d/x/s/v:off/r ""&createobject(""WScript.Shell"").Environment(""PROCESS"")(""_""),,""runas"",1)(window.close)"^) >nul 2>nul))) else (echo This script requires administrator privileges.& pause))& exit /b)

set _log=
set _args=%*
if not defined _args goto :noargs
set _args=%_args:"=%
set _args=%_args:(=%
set _args=%_args:)=%
for %%A in (%_args%) do (if /i "%%A"=="-log" (set "_log=>> %~n0.log"))
:noargs

if defined _log (echo Logging to file %~n0.log) else (echo Logging to stdout)
echo Has admin permissions %_log%
echo Working dir: "%cd%" %_log%
echo Script dir: "%~dp0" %_log%
echo Script path: "%~f0" %_log%
echo Args: %* %_log%

echo Hello World! %_log%

pause

执行:logtest.bat -log 通过添加参数-log，输出将记录到文件中，而不是记录到stdout。

封闭的思想

让我困惑的是，即使在UAC存在了15年之后，一个简单的“ELEVATE”指令还没有被引入到批处理中。也许有一天微软会振作起来。在那之前，我们只能求助于这些黑客。

您可以使用psexec的-h选项让脚本调用自身以提升运行。

我不确定你如何检测到它是否已经处于升高状态……也许只有在出现“访问被拒绝”错误时才会重新尝试提升烫发?

或者，你可以简单地让xcopy和reg.exe命令总是使用psexec -h运行，但是如果最终用户每次都需要输入密码(或者如果你在脚本中包含密码则不安全)，这对他们来说会很烦人……

我把这个粘贴在脚本的开头:

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\icacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    echo args = "" >> "%temp%\getadmin.vbs"
    echo For Each strArg in WScript.Arguments >> "%temp%\getadmin.vbs"
    echo args = args ^& strArg ^& " "  >> "%temp%\getadmin.vbs"
    echo Next >> "%temp%\getadmin.vbs"
    echo UAC.ShellExecute "%~s0", args, "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs" %*
    exit /B

:gotAdmin
    if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
    pushd "%CD%"
    CD /D "%~dp0"
