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?
本·格里普卡的解决方案导致了无限循环。他的批处理是这样工作的(伪代码):
IF "no admin privileges?"
"write a VBS that calls this batch with admin privileges"
ELSE
"execute actual commands that require admin privileges"
正如你所看到的，如果VBS请求管理员权限失败，这将导致一个无限循环。
但是，尽管已经成功请求了管理权限，但仍可能发生无限循环。
本·格里普卡批处理文件中的检查很容易出错。我对批处理进行了研究，并观察到尽管检查失败，但管理权限可用。有趣的是，如果我从windows资源管理器启动批处理文件，检查按预期工作，但当我从我的IDE启动它时，它没有。
所以我建议使用两个单独的批处理文件。第一个生成VBS，调用第二个批处理文件:
@echo off
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
set params = %*:"=""
echo UAC.ShellExecute "cmd.exe", "/c ""%~dp0\my_commands.bat"" %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
del "%temp%\getadmin.vbs"
第二个文件名为“my_commands.bat”，与第一个文件位于同一目录，包含您的实际命令:
pushd "%CD%"
CD /D "%~dp0"
REM Your commands which require admin privileges here
这不会导致无限循环，也会删除容易出错的管理特权检查。
还有来自这篇文章的FSUTIL查询，也在ss64.com上有链接，有以下代码:
@Echo Off
Setlocal
:: First check if we are running As Admin/Elevated
FSUTIL dirty query %SystemDrive% >nul
if %errorlevel% EQU 0 goto START
::Create and run a temporary VBScript to elevate this batch file
Set _batchFile=%~f0
Set _Args=%*
:: double up any quotes
Set _batchFile=""%_batchFile:"=%""
Set _Args=%_Args:"=""%
Echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\~ElevateMe.vbs"
Echo UAC.ShellExecute "cmd", "/c ""%_batchFile% %_Args%""", "", "runas", 1 >> "%temp%\~ElevateMe.vbs"
cscript "%temp%\~ElevateMe.vbs"
Exit /B
:START
:: set the current directory to the batch file location
cd /d %~dp0
:: Place the code which requires Admin/elevation below
Echo We are now running as admin [%1] [%2]
pause
只要FSUTIL存在，它就是一个可靠的替代方案。
基于toster-cx的帖子和本页上其他有趣的帖子，我对如何配置和解决我的问题有了深入的了解。我也遇到过类似的问题，我希望磁盘清理工具每周在周一和周四的午餐时间(比如下午2点)运行两次。然而，这需要更高的权利。
共享批处理文件，这可能会帮助其他初学者像我-
@echo off
echo Welcome to scheduling 'PC Maintenance Activity'
ping localhost -n 3 >nul
echo -- Step - 1 of 3 : Please give 'Admin' rights on next screen
ping localhost -n 5 >nul
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit)
cls
echo -- Step - 2 of 3 : In next screen, select temp areas for cleaning
during routine scheduled activity
ping localhost -n 3 >nul
C:\Windows\System32\cleanmgr.exe /sageset:112
cls
echo Now scheduling maintenance activity...
SchTasks /Create /SC WEEKLY /D MON,THU /TN PC_Cleanup /TR
"C:\Windows\System32\cleanmgr.exe "/sagerun:112 /ST 14:00
cls
echo -- Thanks for your co-operation --
echo -- Maintenance activity is scheduled for --
echo -- Every Monday and Thursday at 2 pm --
ping localhost -n 10 >nul

他的帖子有助于在调度任务时配置可选参数。
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。
