How to print out information about Task Scheduler in powershell script?

Question

I am trying to print out information from the Task Scheduler from the local computer in a PowerShell script so other users can print out this information as well and not have to access the Task Scheduler. I need the script to print out

• name,
• status,
• triggers,
• next run time,
• last run time,
• last run result,
• author,
• created.

I can print out the information about the name, next run time, and last run time, but the rest won't print out when I run the script.

I have already got a little start on my script and got the fields down.

$schedule = new-object -com("Schedule.Service") 
$schedule.connect() 
$tasks = $schedule.getfolder("\").gettasks(0)

$tasks | select Name,Status,Triggers,NextRunTime,LastRunTime,LastRunResult,Author,Created | ft

foreach ($t in $tasks)
{
foreach ($a in $t.Actions)
{
$a.Path
}
}

Any help or suggestions would be appreciated.

Below is a screenshot with what i am looking for and what fields arent printing out data:

Server 2012 R2 and Windows 8.1 have Task Scheduler cmdlets, and this module can be copied and used on a Windows 7 machine, presumably it probably needs the latest .NET and the Windows Management Framework as well. I'm able to disable and re-enable scheduled tasks, as well as display task information. Currently I don't know of built-in cmdlets that give me this information or allow this control.

To list all the scheduled tasks on the machine:

Get-ScheduledTask

You can get the following members from the task sequence object:

PS C:\BigHomie> $A = Get-ScheduledTask | select -First 1

PS C:\BigHomie> $A

This could be cleaned up a bit (i.e. mapping LastRunResult codes). Let me know if you need help. Triggers are a bit more difficult since I don't think the plain English representation you see when viewing a task in the GUI exists in the COM object. I believe it would have to be built from the TriggerCollection stored in RegisteredTask.Definition.Triggers

$sched = New-Object -Com "Schedule.Service"
$sched.Connect()
$out = @()
$sched.GetFolder("\").GetTasks(0) | % {
    $xml = [xml]$_.xml
    $out += New-Object psobject -Property @{
        "Name" = $_.Name
        "Status" = switch($_.State) {0 {"Unknown"} 1 {"Disabled"} 2 {"Queued"} 3 {"Ready"} 4 {"Running"}}
        "NextRunTime" = $_.NextRunTime
        "LastRunTime" = $_.LastRunTime
        "LastRunResult" = $_.LastTaskResult
        "Author" = $xml.Task.Principals.Principal.UserId
        "Created" = $xml.Task.RegistrationInfo.Date
    }
}

$out | fl Name,Status,NextRuNTime,LastRunTime,LastRunResult,Author,Created
