如何在 Windows 10 上停止关机并使用 Powershell 做一些事情

Question

我想创建一个脚本来检测并延迟 Windows 10 台 PC 的关机，并在关机时插入 U 盘时显示一条消息。

我的问题是我的脚本没有停止关机。我对 Powershell 很陌生。对不起我的英语。

这是我得到的：

[System.Reflection.Assembly]::Load("System.Management, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

$Man = New-Object System.Management.ManagementClass("Win32_USBHub")
[System.Management.ManagementObjectCollection]$Devs = $Man.GetInstances()

$global:shuttingDown = $false
$sysevent = [microsoft.win32.systemevents]
Register-ObjectEvent -InputObject $sysevent -EventName "SessionEnding" -Action {$global:shuttingDown = $true; Write-Host "  SessionEnding"} 
Register-ObjectEvent -InputObject $sysevent -EventName "SessionEnded"  -Action {$global:shuttingDown = $true; Write-Host "  SessionEnded"} 

do {
    Start-Sleep -Seconds 1
        if ($global:shuttingDown) {
            & "$env:SystemRoot\System32\Shutdown.exe" -a ;

            $Devs | ForEach-Object {
            if($_.GetPropertyValue("Name").ToString() -eq "USB-Massenspeichergerät"){

                Add-Type -AssemblyName PresentationCore,PresentationFramework
                $ButtonType = [System.Windows.MessageBoxButton]::Ok
                $MessageboxTitle = “USB-Stick gefunden”
                $Messageboxbody = “Es wurde ein USB-Stick gefunden. Nicht vergessen mitzunehmen ;)”
                $MessageIcon = [System.Windows.MessageBoxImage]::Warning
                [System.Windows.MessageBox]::Show($Messageboxbody,$MessageboxTitle,$ButtonType,$messageicon)

                Write-Output ""
                Write-Output $_.GetPropertyValue("Name").ToString()
                Write-Output ""
            }
            $Devs.Dispose()
            $Man.Dispose()
        }
    }
    Write-Host "  Waiting for Shutdown"
} while ($true)

谢谢你的帮助

所以基本上，如果 $global:shuttingDown 保持价值然后使用 Break

do {
    Start-Sleep -Seconds 1
    if ($global:shuttingDown) {break}
    Write-Host " Waiting for Shutdown"
} while ($true)
