register-shutdown-task.ps1

# 從晚上十二點到早上八點、每隔 10 分鐘的每個時間點
$timeArray = for ($i = 0; $i -le 480; $i += 10) {
    $hours = [math]::Floor($i / 60)
    $minutes = $i % 60

    "{0:00}:{1:00}" -f $hours, $minutes
}

# shutdown action, the command is `shutdown.exe /s /t 0`
$action = New-ScheduledTaskAction -Execute "shutdown.exe" -Argument "/s /t 0"

foreach ($timeString in $timeArray) {
    # NOTE: Task 名稱不可包含冒號
    $taskName = "於 $timeString 分時將電腦關機" -Replace ":", " 點 "

    # run daily at the specified time
    $trigger = New-ScheduledTaskTrigger -Daily -At "$timeString"

    $null = Register-ScheduledTask -TaskName "$taskName" -Trigger $trigger -Action $action

    Write-Host "成功註冊排程: $taskName"
