Here’s a list of all Chrome components, how to update them individually, and what they mean.
Google Chrome automatically updates itself in the background, just like Windows 10. The best thing is, unlike Windows 10, Chrome waits until you restart the browser manually to apply the downloaded updates. While updating the Chrome browser, it also automatically updates relevant components, if the update is available.
However, there will be times when Chrome might fail to update one or more of the components. In those situations, depending on the Chrome component, you might have to deal with crashes, odd behavior, and slowness.
When that happens, you can individually update any Chrome component with a single click.
What Are Chrome Components?
You can think of Chrome components as simple individual modules that help Chrome work properly. Each of these components is responsible for a wide range of features. For instance, Adobe Flash component is required to play Flash content, WideVine is required to decrypt DRM protect content like Netflix videos, etc.
All the Chrome components are listed in a single page along with their status and version number. You can visit that page by entering
chrome://components in the Chrome address bar. As of writing this, there are 13 components in Chrome. Each and every component has its own update button so that you can individually update the component.
Like I said before when one or more components are corrupted or not updated properly, Chrome can give you problems. If that’s the case, just click on the “Check for update” button underneath the component. This action will trigger the update process and if the update is available, it will be downloaded and installed automatically.
Of course, as and when needed, Google can add or remove components in Chrome. Which simply means that depending on the Chrome version, you might see less or more components.
Chrome Components List
MEI Preload: It’s a media module that is responsible for preloading media content in the browser. If there is a problem with this module or if it is outdated, it can cause problems with media playback and preloading.
Intervention Policy Database: Chrome has different policies in a contained databased that it pushes to user devices to make the browser work properly and securely. If your chrome browser is crashing constantly, the Intervention Policy Database might be the problem.
Subresource Filter Rules: This module hosts all the rules related to Subresource. Subresource is a simple mechanism that checks the filtered pages to identify and filter out malicious or dangerous content, like phishing and malicious links.
Additionally, the same Subresource filter rules are used to filter out ads that violate Better Ads Standard (https://www.betterads.org/standards/).
Certificate Error Assistant: CEA module is dynamically updated with the captive portal certificate list. This is list is used to handle any SSL errors or problems.

CRLSet: CRLSet module is responsible for blocking certificates in emergency and non-emergency situations.
pnacl: Portable Native Client (pnacl) module is developer component. This component lets a developer run and test untrusted code in a contained and secure Chrome sandbox.

Origin Trials: This is another developer-centric feature. This module allows devs to experiment with web platform features without messing up the Chrome browser.
Adobe Flash Player: This is your good old Adobe Flash Player component that is responsible for dealing with Flash content. Since flash content is slowly being removed, expect this module to be removed.
Widevine Content Decryption Module: Widevine Content Decryption module helps decrypt DRM protected media, like Netflix videos, Spotify music, etc..
Signed Tree Heads: This is a simple module that verifies the signed certificate timestamps.
That is all. Hope the Chrome component list helps you. If you like this article, do check out how to reduce Chrome cache size in Windows 10 to free up disk space.
