Reset PowerShell and Command Prompt contains a registry file and four shortcuts that enable you to restore PowerShell or the Command Prompt to their default settings as explained in this tutorial.
Both Windows PowerShell and the Command Prompt can be customized or modified; however, there is no option to reset to the default settings if problems occur; until now.
You can replace the Powershell links with the included files to reset PowerShell or delete a registry key or use the included registry file to reset Command Prompt.
A tutorial link is also included in the ZIP file if you forget where you got the files from.
