Create a scheduled task to run after a service is started using Powershell?

Question

I've looked at this question where it's shown how to create a trigger to run after a service is started, but I'm struggling to figure out how to do this via Powershell.

New-ScheduledTaskTrigger seems to only support time-based triggers, but not based on an event, like a service starting. Any pointers?

New-ScheduledTaskTrigger unfortunately does not have a way to create event driven triggers. The PS community has requested that this be implemented.

We should be able to combine the XML you're working with with code that creates tasks using .NET. Just replace the user, pass, and service name.

$taskRunAsuser = "domain\user"
$taskRunAsUserPwd = "password"
$Service = new-object -ComObject ("Schedule.Service")
$Service.Connect($env:computername)
$RootFolder = $Service.GetFolder("\")
$TaskDefinition = $Service.NewTask(0)
$settings = $taskDefinition.Settings
$settings.Enabled = $true
$settings.StartWhenAvailable = $true
$settings.Hidden = $false
$Triggers = $TaskDefinition.Triggers
$Trigger = $Triggers.Create(0)
#$Trigger.Id = '4800'
$Trigger.Subscription = "<QueryList> 
<Query Id='0'> 
   <Select Path='System'> 
      *[EventData[Data[@Name='param1'] and (Data='YOUR SERVICE NAME')]] 
      and
      *[EventData[Data[@Name='param2'] and (Data='running')]] 
    </Select> 
</Query> 
</QueryList>"
$Trigger.Enabled = $true
$Action = $TaskDefinition.Actions.Create(0)
$Action.Path = 'ping.exe'
$Action.Arguments = '8.8.8.8 > C:\ping.log'
$rootFolder.RegisterTaskDefinition('Test',$TaskDefinition,6,$taskRunAsUser,$taskRunAsUserPwd,1)
