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");

我正在使用下面的解决方案。它通过转录特性处理stdout/stderr，并将退出码正确地传递给父进程。您需要调整文本路径/文件名。

If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{ 
  echo "* Respawning PowerShell child process with elevated privileges"
  $pinfo = New-Object System.Diagnostics.ProcessStartInfo
  $pinfo.FileName = "powershell"
  $pinfo.Arguments = "& '" + $myinvocation.mycommand.definition + "'"
  $pinfo.Verb = "RunAs"
  $pinfo.RedirectStandardError = $false
  $pinfo.RedirectStandardOutput = $false
  $pinfo.UseShellExecute = $true
  $p = New-Object System.Diagnostics.Process
  $p.StartInfo = $pinfo
  $p.Start() | Out-Null
  $p.WaitForExit()
  echo "* Child process finished"
  type "C:/jenkins/transcript.txt"
  Remove-Item "C:/jenkins/transcript.txt"
  Exit $p.ExitCode
} Else {
  echo "Child process starting with admin privileges"
  Start-Transcript -Path "C:/jenkins/transcript.txt"
}

# Rest of your script goes here, it will be executed with elevated privileges

我找到了一个方法…

创建一个批处理文件打开你的脚本:

@echo off
START "" "C:\Scripts\ScriptName.ps1"

然后创建一个快捷方式，在桌面上说(右键单击新建->快捷方式)。

然后粘贴到位置:

C:\Windows\System32\runas.exe /savecred /user:*DOMAIN*\*ADMIN USERNAME* C:\Scripts\BatchFileName.bat

第一次打开时，您必须输入一次密码。然后将其保存在Windows凭据管理器中。

在此之后，您应该能够以管理员身份运行，而无需输入管理员用户名或密码。

在Shay Levy的答案之上，遵循下面的设置(只有一次)

以管理员权限启动PowerShell。 在堆栈溢出问题PowerShell说“脚本的执行在这个系统上是禁用的。” 例如，将.ps1文件放在任何PATH文件夹中。Windows \ System32系统文件夹

设置之后:

按Win + R 调用powershell Start-Process powershell -Verb runAs <ps1_file>

现在，您可以在一个命令行中运行所有内容。上述操作适用于Windows 8 Basic 64位。

@pgk和@Andrew Odri的回答的问题是当您有脚本参数时，特别是当它们是强制性的时。可以通过以下方法解决此问题:

用户右键单击.ps1文件并选择“使用PowerShell运行”:通过输入框向他询问参数(这是比使用HelpMessage参数属性更好的选择); 用户通过控制台执行脚本:允许他传递所需的参数，并让控制台强制他通知必须的参数。

下面是如何将是代码，如果脚本有计算机名和端口强制参数:

[CmdletBinding(DefaultParametersetName='RunWithPowerShellContextMenu')]
param (
    [parameter(ParameterSetName='CallFromCommandLine')]
    [switch] $CallFromCommandLine,

    [parameter(Mandatory=$false, ParameterSetName='RunWithPowerShellContextMenu')]
    [parameter(Mandatory=$true, ParameterSetName='CallFromCommandLine')]
    [string] $ComputerName,

    [parameter(Mandatory=$false, ParameterSetName='RunWithPowerShellContextMenu')]
    [parameter(Mandatory=$true, ParameterSetName='CallFromCommandLine')]
    [UInt16] $Port
)

function Assert-AdministrativePrivileges([bool] $CalledFromRunWithPowerShellMenu)
{
    $isAdministrator = ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

    if ($isAdministrator)
    {
        if (!$CalledFromRunWithPowerShellMenu -and !$CallFromCommandLine)
        {
            # Must call itself asking for obligatory parameters
            & "$PSCommandPath" @script:PSBoundParameters -CallFromCommandLine
            Exit
        }
    }
    else
    {
        if (!$CalledFromRunWithPowerShellMenu -and !$CallFromCommandLine)
        {
            $serializedParams = [Management.Automation.PSSerializer]::Serialize($script:PSBoundParameters)

            $scriptStr = @"
                `$serializedParams = '$($serializedParams -replace "'", "''")'

                `$params = [Management.Automation.PSSerializer]::Deserialize(`$serializedParams)

                & "$PSCommandPath" @params -CallFromCommandLine
"@

            $scriptBytes = [System.Text.Encoding]::Unicode.GetBytes($scriptStr)
            $encodedCommand = [Convert]::ToBase64String($scriptBytes)

            # If this script is called from another one, the execution flow must wait for this script to finish.
            Start-Process -FilePath 'powershell' -ArgumentList "-ExecutionPolicy Bypass -NoProfile -EncodedCommand $encodedCommand" -Verb 'RunAs' -Wait
        }
        else
        {
            # When you use the "Run with PowerShell" feature, the Windows PowerShell console window appears only briefly.
            # The NoExit option makes the window stay visible, so the user can see the script result.
            Start-Process -FilePath 'powershell' -ArgumentList "-ExecutionPolicy Bypass -NoProfile -NoExit -File ""$PSCommandPath""" -Verb 'RunAs'
        }

        Exit
    }
}

function Get-UserParameters()
{
    [string] $script:ComputerName = [Microsoft.VisualBasic.Interaction]::InputBox('Enter a computer name:', 'Testing Network Connection')

    if ($script:ComputerName -eq '')
    {
        throw 'The computer name is required.'
    }

    [string] $inputPort = [Microsoft.VisualBasic.Interaction]::InputBox('Enter a TCP port:', 'Testing Network Connection')

    if ($inputPort -ne '')
    {
        if (-not [UInt16]::TryParse($inputPort, [ref]$script:Port))
        {
            throw "The value '$inputPort' is invalid for a port number."
        }
    }
    else
    {
        throw 'The TCP port is required.'
    }
}

# $MyInvocation.Line is empty in the second script execution, when a new powershell session
# is started for this script via Start-Process with the -File option.
$calledFromRunWithPowerShellMenu = $MyInvocation.Line -eq '' -or $MyInvocation.Line.StartsWith('if((Get-ExecutionPolicy')

Assert-AdministrativePrivileges $calledFromRunWithPowerShellMenu

这里有一些答案是接近的，但比所需的工作多了一些。

为脚本创建一个快捷方式，并将其配置为“以管理员身份运行”:

创建快捷方式。 右键单击快捷方式并打开属性… 编辑目标从<script-path>到powershell <script-path> 单击高级…并启用以管理员身份运行
