@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

{

要将命令的输出附加到包含当前日期的文本文件名，可以这样做:

$winupdfile = 'Windows-Update-' + $(get-date -f MM-dd-yyyy) + '.txt'
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`"" -Verb RunAs; exit } else { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`""; exit }

下面是Powershell脚本的自我提升代码片段，它保留了工作目录:

if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
    Start-Process PowerShell -Verb RunAs "-NoProfile -ExecutionPolicy Bypass -Command `"cd '$pwd'; & '$PSCommandPath';`"";
    exit;
}

# Your script here

保存工作目录对于执行路径相关操作的脚本很重要。几乎所有其他答案都不保留此路径，这可能会在脚本的其余部分中导致意外错误。

如果您不愿意使用自我提升的脚本/片段，而只是想以管理员身份简单地启动脚本(例如;从浏览器上下文菜单)，在这里看到我的另一个答案:https://stackoverflow.com/a/57033941/2441655

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。

我发现最可靠的方法是将其包装在一个自动提升的。bat文件中:

@echo off
NET SESSION 1>NUL 2>NUL
IF %ERRORLEVEL% EQU 0 GOTO ADMINTASKS
CD %~dp0
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 0); close();"
EXIT

:ADMINTASKS

powershell -file "c:\users\joecoder\scripts\admin_tasks.ps1"

EXIT

.bat检查您是否已经是管理员，并在需要时以管理员身份重新启动脚本。它还防止多余的“cmd”窗口打开ShellExecute()的第4个参数设置为0。

另一个更简单的解决方案是，你也可以右键单击“C:\Windows\System32\cmd.exe”，并选择“以管理员身份运行”，然后你就可以以管理员身份运行任何应用程序，而无需提供任何密码。
