加上我的意见。我的简单版本基于net session，到目前为止一直在Windows 7 / Windows 10中工作。为什么要过于复杂呢?

if (!(net session)) {$path =  "& '" + $myinvocation.mycommand.definition + "'" ; Start-Process powershell -Verb runAs -ArgumentList $path ; exit}

只需添加到脚本顶部，它将以管理员身份运行。

如果当前控制台没有被提升，并且您正在尝试执行的操作需要提升权限，那么您可以使用以管理员身份运行选项启动powershell:

PS> Start-Process powershell -Verb runAs

Microsoft Docs: Start-Process

您需要使用管理权限重新运行脚本，并检查脚本是否在该模式下启动。下面我写了一个脚本，它有两个函数:DoElevatedOperations和DoStandardOperations。您应该将需要管理权限的代码放在第一个中，将标准操作放在第二个中。IsRunAsAdmin变量用于标识管理模式。

我的代码是微软脚本的简化摘录，当你为Windows Store应用程序创建应用程序包时自动生成。

param(
    [switch]$IsRunAsAdmin = $false
)

# Get our script path
$ScriptPath = (Get-Variable MyInvocation).Value.MyCommand.Path

#
# Launches an elevated process running the current script to perform tasks
# that require administrative privileges.  This function waits until the
# elevated process terminates.
#
function LaunchElevated
{
    # Set up command line arguments to the elevated process
    $RelaunchArgs = '-ExecutionPolicy Unrestricted -file "' + $ScriptPath + '" -IsRunAsAdmin'

    # Launch the process and wait for it to finish
    try
    {
        $AdminProcess = Start-Process "$PsHome\PowerShell.exe" -Verb RunAs -ArgumentList $RelaunchArgs -PassThru
    }
    catch
    {
        $Error[0] # Dump details about the last error
        exit 1
    }

    # Wait until the elevated process terminates
    while (!($AdminProcess.HasExited))
    {
        Start-Sleep -Seconds 2
    }
}

function DoElevatedOperations
{
    Write-Host "Do elevated operations"
}

function DoStandardOperations
{
    Write-Host "Do standard operations"

    LaunchElevated
}


#
# Main script entry point
#

if ($IsRunAsAdmin)
{
    DoElevatedOperations
}
else
{
    DoStandardOperations
}

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

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"

你可以很容易地添加一些注册表项来为.ps1文件获得“以管理员身份运行”上下文菜单:

New-Item -Path "Registry::HKEY_CLASSES_ROOT\Microsoft.PowershellScript.1\Shell\runas\command" `
-Force -Name '' -Value '"c:\windows\system32\windowspowershell\v1.0\powershell.exe" -noexit "%1"'

(从@Shay更新为一个更简单的脚本)

基本上在HKCR:\Microsoft.PowershellScript。1\Shell\runas\命令设置默认值，使用Powershell调用脚本。
