Edit to add: So far it appears this update fixed the My Cloud not showing up under Computer issue (knock on wood). Started a new thread where I posted images showing pre/post update. People can use that thread to post their experiences with the KB 3140743 update rather than clutter up this thread. Will update OP post with new information if others report success with this update.
