Summary: Use Windows PowerShell in Windows 8.1 to show all running tasks in Task Scheduler.

 Sometimes I get CPU spikes on a server. As part of troubleshooting, I need to know the processes and which
          are scheduled tasks. Is there a way for Windows PowerShell to show me which tasks are running now?

 Use the Get-ScheduledTask cmdlet and filter on the State:

Get-ScheduledTask | Where { $_.State –eq ‘Running’ }
