How does this work? Basically, in the background, Chrome will download the latest update whenever there is one available, and whenever you restart your browser or computer, the update will be applied the next time you launch the browser. This means that users never need to worry or wonder if they run the latest version of Chrome, because give it enough time and it will automatically download the latest update and install itself. One of the useful features of Google Chrome is that it can update itself automatically in the background.
