I am trying to write a batch file for my users to run from their Vista machines with UAC. The file is re-writing their hosts file, so it needs to be run with Administrator permissions. I need to be able to send them an email with a link to the .bat file. The desired behavior is that when they right-click on the file and say Open, they will get one of those UAC dialogs that makes the screen go dark and forces them to answer whether they want to give the application permission to run as administrator. Instead, they are just seeing "Access denied" on the command line window.

有可能采取不同的做法吗?

另一个PowerShell解决方案…

这不是关于作为管理员运行批处理脚本,而是如何从批处理提升另一个程序…

我有一个批处理文件“包装”的exe。它们具有相同的“根文件名”,但扩展名不同。我能够启动exe作为管理员,并将工作目录设置为一个包含脚本,与以下一行powershell调用:

@powershell "Start-Process -FilePath '%~n0.exe' -WorkingDirectory '%~dp0' -Verb RunAs"

更多信息

还有一大堆额外的Start-Process选项,你也可以申请!查看:https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.management/start-process?view=powershell-6

注意,我使用了@前缀。这相当于一行的@echo off。我在这里使用%~n0来获得批处理脚本的“根名称”,然后连接.exe以指向相邻的二进制文件。%~dp0的使用提供了批处理所在目录的完整路径。当然,-Verb RunAs参数提供抬高。

其他回答

由于我在这个脚本弹出一个新的命令提示符并在无限循环中再次运行时遇到了麻烦(使用Win 7 Pro),我建议您尝试另一种方法:我如何自动提升我的批处理文件,以便它在需要时请求UAC管理员权限?

小心,你必须在脚本的末尾添加这个,就像在编辑中说的那样,这样你就可以在权限提升后回到脚本目录: CD /d %~dp0

你不能从批处理文件中请求管理权限,但是你可以在%temp%中编写一个windows脚本主机脚本并运行它(它反过来以管理员身份执行你的批处理)。使用“runas”作为动词的应用程序对象

@echo off 
Net session >nul 2>&1 || (PowerShell start -verb runas '%~0' &exit /b)
Echo Administrative privileges have been got. & pause

上述操作适用于我的Windows 10 1903版

这是我的代码!它看起来很大,但主要是注释行(以::)开始的行)。

特点:

全参数转发 不更改工作文件夹 错误处理 接受带圆括号的路径(%TEMP%文件夹除外) 支持UNC路径 映射文件夹检查(警告你如果管理员不能访问映射驱动器) 可以用作外部库(查看我在这个主题的帖子:https://stackoverflow.com/a/30417025/4932683) 可以调用时/如果需要在您的代码中的任何地方

只需将其附加到批处理文件的末尾,或将其保存为库(如上所示)

:RequestAdminElevation FilePath %* || goto:eof
:: 
:: By:   Cyberponk,     v1.5 - 10/06/2016 - Changed the admin rights test method from cacls to fltmc
::          v1.4 - 17/05/2016 - Added instructions for arguments with ! char
::          v1.3 - 01/08/2015 - Fixed not returning to original folder after elevation successful
::          v1.2 - 30/07/2015 - Added error message when running from mapped drive
::          v1.1 - 01/06/2015
:: 
:: Func: opens an admin elevation prompt. If elevated, runs everything after the function call, with elevated rights.
:: Returns: -1 if elevation was requested
::           0 if elevation was successful
::           1 if an error occured
:: 
:: USAGE:
:: If function is copied to a batch file:
::     call :RequestAdminElevation "%~dpf0" %* || goto:eof
::
:: If called as an external library (from a separate batch file):
::     set "_DeleteOnExit=0" on Options
::     (call :RequestAdminElevation "%~dpf0" %* || goto:eof) && CD /D %CD%
::
:: If called from inside another CALL, you must set "_ThisFile=%~dpf0" at the beginning of the file
::     call :RequestAdminElevation "%_ThisFile%" %* || goto:eof
::
:: If you need to use the ! char in the arguments, the calling must be done like this, and afterwards you must use %args% to get the correct arguments:
::      set "args=%* "
::      call :RequestAdminElevation .....   use one of the above but replace the %* with %args:!={a)%
::      set "args=%args:{a)=!%"

如何使用它的例子

:EXAMPLE
@echo off

 :: Run this script with elevation
 call :RequestAdminElevation "%~dpfs0" %* || goto:eof
 
  echo/I now have Admin rights!
  echo/
  echo/Arguments using %%args%%:    %args%
  echo/Arguments using %%*: %*
  echo/%%1= %~1
  echo/%%2= %~2
  echo/%%3= %~3

  echo/
  echo/Current Directory: %CD%
  echo/
  echo/This file: %0
  echo/

pause &goto:eof

[here you paste the RequestAdminElevation function code]

另一种方法是

在本地创建快捷方式并将其设置为调用管理员权限(属性,高级,以管理员身份运行)

然后

向用户发送快捷方式(或指向快捷方式的链接,而不是指向批处理文件本身的链接)。
