这种行为是经过设计的。因为微软真的不想让.ps1文件成为最新的电子邮件病毒，所以有多层安全措施。有些人认为这与任务自动化的概念相悖，这是公平的。Vista+安全模型是“去自动化”的，这样用户就可以接受。

但是，我怀疑如果你启动powershell本身作为提升，它应该能够运行批处理文件，而不需要再次要求密码，直到你关闭powershell。

乔纳森和谢伊·列维发布的代码对我不起作用。

请在下面找到工作代码:

If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{   
#"No Administrative rights, it will display a popup window asking user for Admin rights"

$arguments = "& '" + $myinvocation.mycommand.definition + "'"
Start-Process "$psHome\powershell.exe" -Verb runAs -ArgumentList $arguments

break
}
#"After user clicked Yes on the popup, your file will be reopened with Admin rights"
#"Put your code here"

您可以创建一个批处理文件(*.bat)，在双击时使用管理权限运行powershell脚本。通过这种方式，您不需要更改powershell脚本中的任何内容。要做到这一点，创建一个与powershell脚本名称和位置相同的批处理文件，然后将以下内容放入其中:

@echo off

set scriptFileName=%~n0
set scriptFolderPath=%~dp0
set powershellScriptFileName=%scriptFileName%.ps1

powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"%scriptFolderPath%`\"; & \`\".\%powershellScriptFileName%\`\"`\"\" -Verb RunAs"

就是这样!

下面是解释:

假设powershell脚本位于路径C:\Temp\ScriptTest。ps1，您的批处理文件必须有路径C:\Temp\ScriptTest.bat。当有人执行这个批处理文件时，会发生以下步骤:

The cmd will execute the command powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"C:\Temp\`\"; & \`\".\ScriptTest.ps1\`\"`\"\" -Verb RunAs" A new powershell session will open and the following command will be executed: Start-Process powershell "-ExecutionPolicy Bypass -NoProfile -NoExit -Command `"cd \`"C:\Temp\`"; & \`".\ScriptTest.ps1\`"`"" -Verb RunAs Another new powershell session with administrative privileges will open in the system32 folder and the following arguments will be passed to it: -ExecutionPolicy Bypass -NoProfile -NoExit -Command "cd \"C:\Temp\"; & \".\ScriptTest.ps1\"" The following command will be executed with administrative privileges: cd "C:\Temp"; & ".\ScriptTest.ps1" Once the script path and name arguments are double quoted, they can contain space or single quotation mark characters ('). The current folder will change from system32 to C:\Temp and the script ScriptTest.ps1 will be executed. Once the parameter -NoExit was passed, the window wont be closed, even if your powershell script throws some exception.

使用

#需要-RunAsAdministrator

还没有声明。它似乎是从PowerShell 4.0开始出现的。

http://technet.microsoft.com/en-us/library/hh847765.aspx

当这个switch参数被添加到require语句时， 它指定您所在的Windows PowerShell会话 运行脚本时必须使用提升的用户权限 (以管理员身份运行)。

对我来说，这似乎是一个很好的方法，但我还不确定现场经验。PowerShell 3.0运行时可能会忽略这一点，甚至更糟，会给出一个错误。

当脚本以非管理员身份运行时，会给出以下错误:

脚本“StackOverflow.”Ps1 '不能运行，因为它包含 以管理员身份运行的“#requires”语句。当前的 Windows PowerShell会话没有以管理员身份运行。开始 Windows PowerShell使用“以管理员身份运行”选项，然后 尝试再次运行脚本。 + CategoryInfo: PermissionDenied:(StackOverflow.ps1:String) []， ParentContainsErrorRecordException + fullyqualifiederrid: ScriptRequiresElevation

Benjamin Armstrong发表了一篇关于自提升PowerShell脚本的优秀文章。他的代码有一些小问题;下面是基于评论中建议的修复的修改版本。

基本上，它获取与当前进程相关联的身份，检查它是否是管理员，如果不是，就创建一个具有管理员权限的新PowerShell进程，并终止旧进程。

# Get the ID and security principal of the current user account
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);

# Get the security principal for the administrator role
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;

# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole))
{
    # We are running as an administrator, so change the title and background colour to indicate this
    $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
    $Host.UI.RawUI.BackgroundColor = "DarkBlue";
    Clear-Host;
}
else {
    # We are not running as an administrator, so relaunch as administrator

    # Create a new process object that starts PowerShell
    $newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";

    # Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
    $newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"

    # Indicate that the process should be elevated
    $newProcess.Verb = "runas";

    # Start the new process
    [System.Diagnostics.Process]::Start($newProcess);

    # Exit from the current, unelevated, process
    Exit;
}

# Run your code that needs to be elevated here...

Write-Host -NoNewLine "Press any key to continue...";
$null = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown");
