通过 Powershell 作为 System32 创建任务

Question

我想通过 Powershell 创建一个任务，但我得到了这个错误：

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

• Register-ScheduledTask "Bot_Activation" -InputObject $Task
• 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...我该如何解决这个问题？是否可以将 Task 创建为 System32？

这是脚本：

$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 

这是调用脚本的代码：

subprocess.Popen([r'C:\\WINDOWS\\system32\WindowsPowerShell\\v1.0\\powershell.exe',
                         '-ExecutionPolicy',
                         'Unrestricted',
                         './setup_bot_task.ps1'], cwd=os.getcwd())

您需要使用“以管理员身份运行”选项运行这是一个提升的会话。

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
