I am trying get a list of all the Windows Task Scheduler tasks, to be later filtered by their Action.

I noticed in Both Windows PowerShell and Powershell ISE when running
Get-ScheduledTask

I only get semi results:

But after running Get-ScheduledTask | Get-ScheduledTaskInfo
Which returns empty:

And then running Get-ScheduledTask
again, it does return full results:

Why Get-ScheduledTask behave diffrently before and after Get-ScheduledTask | Get-ScheduledTaskInfo?
