• 這個計划任務的計划是什么？

Answer 1

您可以使用Get-ScheduledTask和Get-ScheduledTaskInfo cmdlet 獲得所有這些

$task = Get-ScheduledTask <TaskName>
$task | Get-ScheduledTaskInfo # Contains LastRunTime,LastTaskResult
# The schedule info is in the triggers
foreach ($Trigger in $task.Triggers) {
    Switch ($Trigger.CimClass.CimClassName) {
        'MSFT_TaskTimeTrigger' { $TriggerWhen = 'Once' }
        'MSFT_TaskBootTrigger' { $TriggerWhen = 'AtStartup' }
        'MSFT_TaskLogonTrigger' { $TriggerWhen = 'AtLogon' }
        'MSFT_TaskWeeklyTrigger' { $TriggerWhen = 'Weekly' }
        'MSFT_TaskDailyTrigger' { $TriggerWhen = 'Daily' }
    }
    # Other properties of the trigger may be useful such as
    $Trigger.WeeksInterval
    $Trigger.DaysOfWeek # Sunday = 1, Monday = 2, Tuesday = 4, Wednesday = 8, Thursday = 16, Friday = 32, Saturday = 64
}
