通过Powershell作为System32创建任务

Question

我想通过Powershell创建一个任务，但是我得到了以下错误：

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

• Register-ScheduledTask "Bot_Activation“-InputObject $Task

(PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask)注册-ScheduledTask，CimException

• FullyQualifiedErrorId :HRESULT0x80070005，Register-ScheduledTask

我认为这与“管理员”还没有得到足够的rights...How有关，我能解决这个问题吗？是否可以将任务创建为System32？

这是一个脚本：

$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“”选项来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。见此测试

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
