Jobs were introduced in PowerShell 2.0 and helped to solve a problem inherent in the command-line tools. In a nutshell, if you start a long running task, your prompt is unavailable until the task finishes. As an example of a long running task, think of this simple PowerShell command:

Get-ChildItem -Path c:\ -Recurse

It will take a while to fetch full directory list of your C: drive. If you run it as Job then the console will get the control back and you can capture the result later on.


PowerShell Jobs run in a new process. This has pros and cons which are related.


  1. The job runs in a clean process, including environment.
  2. The job can run asynchronously to your main PowerShell process


  1. Process environment changes will not be present in the job.
  2. Parameters pass to and returned results are serialized.
    • This means if you change a parameter object while the job is running it will not be reflected in the job.
    • This also means if an object cannot be serialized you cannot pass or return it (although PowerShell may Copy any parameters and pass/return a PSObject.)
