通过Powershell作为System32创建任务

编程问答 2022-06-13

问题描述

我想通过Powershell创建任务，但出现此错误：

Register-ScheduledTask：访问被拒绝 在C：\ Users \ 4TL4S \ Documents \ Coding \ Bot_Dev \ juri_exc \ ui \ setup_bot_task.ps1：8 Zeichen：1

  • Register-ScheduledTask“ Bot_Activation” -InputObject $ Task 
  • db.response_graphs.aggregate(
    [
        {
            $match : {
                "Response_measure" : "MasksMandatory"
            }
        },{
            $project : {
                date_end: { $replaceAll: { input: "$date_end",find: "NA",replacement: "2020-08-01" }}
            }
        }
        ]
    )
  • CategoryInfo：PermissionDenied：（PS_ScheduledTask：Root / Microsoft / ... S_ScheduledTask） [Register-ScheduledTask]，CimException
  • FullyQualifiedErrorId：HRESULT 0x80070005，Register-ScheduledTask

我认为这与“管理员”没有足够的权限有关...我该如何解决？是否可以将Task创建为System32？

这是脚本：

这是调用脚本的代码：

$Action = New-ScheduledTaskAction -Execute "cmd.exe"
$Trigger = New-ScheduledTaskTrigger -At "0am" -DaysOfWeek 1 -Weekly
$Principle = New-ScheduledTaskPrincipal "Administrator" -RunLevel Highest
$Settings = New-ScheduledTaskSettingsSet
$Task = New-ScheduledTask -Action $Action -Principal $Principle -Trigger $Trigger -Settings $Settings
Register-ScheduledTask "Bot_Activation" -InputObject $Task

解决方法

您需要使用“以管理员身份运行”选项来运行此提升的会话。

您可以将Start-Process与参数-Verb和参数runas一起使用。看这个测试

Start-Process powershell -ArgumentList @'
$Action = New-ScheduledTaskAction -Execute "cmd.exe"
$Trigger = New-ScheduledTaskTrigger -At "0am" -DaysOfWeek 1 -Weekly
$Principle = New-ScheduledTaskPrincipal "Administrator" -RunLevel Highest
$Settings = New-ScheduledTaskSettingsSet
$Task = New-ScheduledTask -Action $Action -Principal $Principle -Trigger $Trigger -Settings $Settings
Register-ScheduledTask "Bot_Activation" -InputObject $Task 
'@ -Verb runas
