Before: ``` PS C:\Users\vboxuser\rust> ./x x.ps1 PS C:\Users\vboxuser\rust> ``` After: ``` PS C:\Users\vboxuser\rust> ./x x.ps1 C:\Users\vboxuser\rust\x.ps1 : C:\Users\vboxuser\rust\x.ps1: error: did not find python installed help: consider installing it from https://www.python.org/downloads/windows/ At line:1 char:1 + ./x + ~~~ + CategoryInfo : NotInstalled: (:) [Write-Error], WriteErrorException + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,x.ps1 ``` The existing message from the shell script is already decent and I decided not to change it: ``` $ ./x Python was not found but can be installed from the Microsoft Store: ms-windows-store://pdp/?productid=9NJ46SX7X90P ```
