Can I Access the Console or Log in a Final Build?

I’d like to monitor my game’s log while it runs as a stand-alone final build (Windows exe). Is there a debugging mode that I can enter? Can I bring up the console?

Is a log written at all when running a windows standalone?

Can I configure it to do so, and perhaps where it should be output’ed?

Or do I need to pull in a custom logging system?

What have others done?
