List of Chromium Components and Their Meaning (2019)

Google Chrome updates in the background so users never have to worry about updating the browser themselves. There is also an easy way to check for pending updates by going to the “About Google Chrome” page using the three-dot menu at the top right. However, both of these methods update Chrome as a whole, and users have no control over the updates. Sometimes a faulty update can cause Chrome to crash, which can frustrate users. Well, there is a way to debug Chrome updates yourself without the need for tech support and this is made possible by Chrome components. In this article, we’re going to talk about Chrome components, what they are, and how they can help you update different parts of Chrome manually.

List of Chrome components

Before we see the list of Chrome components and what they mean, let’s first learn a little about them.

What are Chrome components?

Contrary to settings and indicators of chromium that allow you to enable or disable new features on Chrome, Chrome components are the individual components of Chrome that run in the background and make those features possible. For example, there is a Chrome component called “Widevine Content Decryption Module”.

This module allows Google Chrome to play videos signed with Digital Rights . This means that every time you watch a movie on netflix , Amazon Prime Video or any other streaming service, this add-on allows Chrome to play these videos. Therefore, if your Chrome browser cannot play digital rights protected videos, it means that the “Widevine content decryption module” is corrupted.

How to open Chrome components

You can access the Chrome components page on Google Chrome using the Chrome URL feature. A user must only see the URL page chrome: // components and all the different components of Chrome will be presented to him. To update a Chrome component, it you just click on the button “ Search for bets up to date ”located under this component. The latter will be automatically updated if an update is available.
