我希望我的批处理文件只运行提升。如果没有提升，为用户提供一个选项，以提升的方式重新启动批处理。
我正在编写一个批处理文件来设置一个系统变量，将两个文件复制到Program files位置，并启动一个驱动程序安装程序。如果Windows 7/Windows Vista用户(启用了UAC，即使他们是本地管理员)在没有右键单击并选择“以管理员身份运行”的情况下运行它，他们将得到“访问拒绝”，复制这两个文件并写入系统变量。
如果用户实际上是管理员，我想使用一个命令自动重新启动提升的批处理。否则，如果他们不是管理员，我想告诉他们，他们需要管理员权限来运行批处理文件。我使用xcopy复制文件和REG ADD写入系统变量。我正在使用这些命令来处理可能的Windows XP机器。我在这个主题上发现了类似的问题，但没有一个是关于重新启动批处理文件的。

当一个CMD脚本需要管理员权限，并且你知道它，添加这一行到脚本的最顶部(在@ECHO OFF之后):
NET FILE > NUL 2>&1 || POWERSHELL -ex Unrestricted -Command "Start-Process -Verb RunAs -FilePath '%ComSpec%' -ArgumentList '/c \"%~fnx0\" %*'" && EXIT /b
NET FILE检查现有的Administrator权限。如果没有，PowerShell将在提升的shell中启动当前脚本(带其参数)，并关闭非提升的脚本。

下面的解决方案是干净的，工作完美。
Download Elevate zip file from https://www.winability.com/download/Elevate.zip Inside zip you should find two files: Elevate.exe and Elevate64.exe. (The latter is a native 64-bit compilation, if you require that, although the regular 32-bit version, Elevate.exe, should work fine with both the 32- and 64-bit versions of Windows) Copy the file Elevate.exe into a folder where Windows can always find it (such as C:/Windows). Or you better you can copy in same folder where you are planning to keep your bat file. To use it in a batch file, just prepend the command you want to execute as administrator with the elevate command, like this:
提升网络启动服务…
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"
:--------------------------------------
对于某些程序，将超级秘密的__COMPAT_LAYER环境变量设置为RunAsInvoker可以工作。看看这个:
set "__COMPAT_LAYER=RunAsInvoker"
start regedit.exe
尽管这样，将没有UAC提示用户将继续没有管理权限。
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
我使用了Matt的精彩答案，但我发现在运行提升脚本时，Windows 7和Windows 8系统之间存在差异。
在Windows 8上提升脚本后，当前目录将被设置为c:\Windows\system32。幸运的是，有一个简单的解决方法，将当前目录更改为当前脚本的路径:
cd /d %~dp0
注意:使用cd /d确保驱动器号也被更改。
要测试这一点，可以将以下内容复制到脚本中。在两个版本上正常运行可以看到相同的结果。以Admin身份运行，看看Windows 8的区别:
@echo off
echo Current path is %cd%
echo Changing directory to the path of the current script
cd %~dp0
echo Current path is %cd%
pause
