The Powershell Automatic Variables are created and stored automatically in the Powershell session. This type of variables is read-only. Above all, I don’t recommend you trying to assign some value to these variables.

The Profile variable contains the path to your profile file. For example, in this file you can modify and customize your Powershell environment. To clarify, I wrote more in the post How to speed up your work with Powershell profile.


The next variable is more difficult to explain. By definition, this variable contains the object taken from pipeline.
