当然，如果您有管理员帐户，还可以强制以管理员身份打开应用程序。

找到文件，右键单击>属性>快捷方式>高级，并选择以管理员身份运行

单击“确定”。

以下是对Shay Levi建议的补充(只需在脚本开头添加这些行):

if (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))  
{  
  $arguments = "& '" +$myinvocation.mycommand.definition + "'"
  Start-Process powershell -Verb runAs -ArgumentList $arguments
  Break
}

这将导致当前脚本以管理员模式传递给一个新的powershell进程(如果当前User具有管理员模式，并且脚本不是以管理员身份启动)。

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。

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.

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");

我最近需要在ansible上建立一个环境。我说马上——决定权不在我，但我不记得是从哪里得到的。是这样的:

powershell.exe -NoProfile -ExecutionPolicy Unrestricted -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Unrestricted -Command Get-Service -Name ssh-agent | Set-Service -StartupType Automatic' -Verb RunAs}";

本示例启用ssh-agent自动启动。 所需的命令在-Command后指定。唯一的问题是启动发生在一个新的PS实例上，但到目前为止，这是我所知道的以管理员身份执行命令而不需要额外步骤的唯一方法。
