Automatically export history at end of powershell session

Another way to do it, just in case it's helpful for anyone.

Powershell now stores command history automatically in the file "%userprofile%\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt"

To display the history, I've added a function into my profile like so...

function h2 {
    $h = [System.Environment]::ExpandEnvironmentVariables("%userprofile%\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt")
    cat $h;
}

Now I can just type "h2" to display the full history. Not particularly clever, but effective.

Not perfect, but you can use a shortcut with a start command telling PowerShell to save all history on exit.

1. Right-click your desktop and select New -> Shortcut
2. Enter the following as the shortcut path:

powershell -NoExit -Command $histlog = Register-EngineEvent -SourceIdentifier ([System.Management.Automation.PsEngineEvent]::Exiting) -Action {Get-History | Export-Clixml ~\PowerShell\history.xml}

3. Choose a name for your shortcut and click OK.

If you launch from this shortcut, your history will be saved to ~\PowerShell\history.xml whenever PowerShell gets an exit event.
