Powershell 在启动时使用 ScheduledJob 以管理员权限运行作业 [英] Powershell run job at startup with admin rights using ScheduledJob

问题描述

为了减轻我的一些工作，我创建了一个 powershell 脚本，它需要:

To ease some of my work I have created a powershell script which needs to :

1. 在启动时运行.
2. 使用管理员权限运行，因为它必须写入 c:\program files 文件夹.

我使用 powershell 创建了启动服务，如下所示:

I created the startup service using powershell like this :

function MakeStartupService
{
    Write-Host "Adding script as a startup service"
    $trigger = New-JobTrigger -AtStartup -RandomDelay 00:00:15
    Try
    {
      Register-ScheduledJob -Trigger $trigger -FilePath "absolute_path" -Name "Job-name" -EA Stop
    }
    Catch [system.exception]
    {
        Write-Host "Looks like an existing startup service exists for the same. Overwriting existing job"
        Unregister-ScheduledJob "Job-name"
        Register-ScheduledJob -Trigger $trigger -FilePath "absolute_path" -Name "Job-name"
    }
}

该作业已成功注册为启动服务，并且在任务调度程序中可见.如果我使用 Start-Job -DefinitionName Job-name 或通过从 Task Scheduler 中右键单击来启动它，它可以正常工作，但在 Windows 启动时它不会启动.

The job is registered as a startup service successfully and is visible inside task scheduler. If I start it using Start-Job -DefinitionName Job-name or by right clicking from Task Scheduler, it works fine but it doesn't start when windows starts.

目前我正在我的个人 Windows 10 系统上对此进行测试，并在另一个 Windows 10 系统中进行了检查，但该行为仍然是名称.我正在附上这项工作的任务计划程序窗口的屏幕截图.

Currently I am testing this on my personal Windows 10 system, and have checked in another windows 10 system but the behavior remained name. I am attaching screenshot of task scheduler window for this job.

抱歉，如果这个问题听起来重复或愚蠢(我是 powershell 的初学者)，但相信我，我在网上找到的所有解决方案都无法解决这个问题.

Sorry if this questions sounds repeated or dumb (I am a beginner in powershell), but believe me, none of the solutions I found online worked for this.

提前致谢！！

推荐答案

这是我使用的已经在生产中的代码.如果它对您不起作用，那么您的系统肯定有其他问题.

This is code that is already in production that I use. If it does not work for you, you must have something else going on with your system.

function Invoke-PrepareScheduledTask
{
    $taskName = "UCM_MSSQL"
    $task = Get-ScheduledTask -TaskName $taskName -ErrorAction SilentlyContinue
    if ($task -ne $null)
    {
        Unregister-ScheduledTask -TaskName $taskName -Confirm:$false 
    }

    # TODO: EDIT THIS STUFF AS NEEDED...
    $action = New-ScheduledTaskAction -Execute 'powershell.exe' -Argument '-File "C:\Invoke-MYSCRIPT.ps1"'
    $trigger = New-ScheduledTaskTrigger -AtStartup -RandomDelay 00:00:30
    $settings = New-ScheduledTaskSettingsSet -Compatibility Win8

    $principal = New-ScheduledTaskPrincipal -UserId SYSTEM -LogonType ServiceAccount -RunLevel Highest

    $definition = New-ScheduledTask -Action $action -Principal $principal -Trigger $trigger -Settings $settings -Description "Run $($taskName) at startup"

    Register-ScheduledTask -TaskName $taskName -InputObject $definition

    $task = Get-ScheduledTask -TaskName $taskName -ErrorAction SilentlyContinue

    # TODO: LOG AS NEEDED...
    if ($task -ne $null)
    {
        Write-Output "Created scheduled task: '$($task.ToString())'."
    }
    else
    {
        Write-Output "Created scheduled task: FAILED."
    }
}
