Final answer:
PowerShell v5+ stores the last 4096 commands in a file called ConsoleHost_history.txt, which is located in the user's AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine directory. This history can also be accessed using the Get-History cmdlet within PowerShell.
Step-by-step explanation:
In PowerShell version 5 and later, you can view a history of the last 4096 commands executed by using the feature known as console history. This console history is automatically saved and can be accessed using the Get-History cmdlet. However, if you want to see the actual history file, PowerShell uses a file located in your user profile directory to store this information. The file is called ConsoleHost_history.txt, and its default path is %userprofile%\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt. You can navigate to this directory in File Explorer or use the Get-Content cmdlet in PowerShell to view the contents of the file directly.
