How can I get the path of a Windows shortcut that runs my PowerShell script?

If you're looking to do something like allow the script to run just once, that's a bit tricky. Shortcuts don’t communicate back to PowerShell, so you might consider using a command-line argument when launching the script. A simpler way to manage script runs could be to use a system where you check for a ticket or a record to see if it has been executed.

The Windows shortcut doesn’t provide that kind of direct feedback. You could explore using `$PSBoundParameters`, `$PSScriptRoot`, and `$MyInvocation` for some details, but if you require certainty, try using a batch file that utilizes `%~dp0` to execute your PowerShell script.

To get the shortcut path from your script, you might want to check out the `Get-StartupInfo` function from jborean93's `ProcessEx` module. You can find out whether your script was launched via a shortcut by checking certain flags.

Unfortunately, the script itself can't inherently know if it was launched through a shortcut or what that shortcut's path is. You'd either need to pass that information as a parameter when calling the script, but that creates a bit of a problem because the code calling the script would also need to know where to get the shortcut path from, which can feel like a catch-22. Separating the script execution and shortcut removal might be the best route here.
