The only thing you are missing is some error handling. You could add a #requires -module statement in the file,

Yeah... And esteemed colleague pointed that out to me.... 😉

Try/Catch didn't catch any errors, that's why I opted for show/query solution... I am curious though how to go about doing proper error-handeling for exe... $LastExitCode or $?

I feel a teachable moment coming on... 😃
