So, there is no excuse for Windows and Mac users to run Chrome with an old version of Flash. The only downside is that on Chrome OS (tested on version 49) Flash is not an available component. In my tests, the Chrome Component Updater worked consistently across Windows, OS X and Chrome OS. If your computer is slow and/or the component is large, you may briefly see a "component downloading" message too. If there is no available update, the button click response is "Component not updated". The "Component updated" message in the screen shot above is the result of upgrading Flash from version 21.0.0.213 to 21.0.0.216.
Simply click the gray "Check for update" button and the Chrome Component Updater will not only check for updates, it will also download and install an available update. The Flash Player is identified as "pepper_flash". There are six components on OS X 10.10, eight on Windows 7, nine on Windows 8.1 and two on Chrome OS 49.
The screen shot above, taken on Windows 10, indicates there are nine, only the first five are shown. When a user logs in to their eFiling page and clicks on the My Tax Return (ITR12) link to submit their return, they may be greeted with a you need the latest version of Flash to access this.
The number of Chrome components varies by operating system. The interface is a URL, chrome://components
The tip that I received (thanks Michael) was that there is, in fact, an interface to it, and, that the Component Updater can be used to update Flash. The latest version of google browser prompts Adobe Flash Player plug has been blocked Turn: Solve the problem that the browser Adobe Flash Player is not the latest version Install the latest Adobe Flash Player on Ubuntu 18. The downside, for me at least, has been that there was no interface to the Chrome Component Updater. The article says that the "Chrome Component Updater allows the Chrome engineering team to release small updates to parts of Chrome on a very rapid schedule." Compared to the full browser update, the article notes that the Component Updater uses a small amount of bandwidth and only runs when the browser itself is running. Google mentions this in an article targeted at IT administrators called Manage Chrome updates on Windows. It makes a good first impression.
