Do you know by chance where it was saved? You can double click files with your mouse to open them, if thats whats being asked.
If not, can you possibly clarify a bit?
Edit: I just thought of something about a minute after posting. If the default Windows 10 player does not play it/audio, you can I believe right click on it to open a menu that should say "Open With" somewhere. Hover over that, and it should list what you could play it with.
(Keep in mind this is only if you have another player installed and if it does not play correctly at first. If not, ignore the extra complication.)
