Not only has this contributed to the gap between Chromium browsers and Edge, but it also serves as a good reason for Microsoft to base its new browser on Chromium. It is a fact that Windows 10 is now used by over 400 million users globally but lately, its updates have been causing users a great deal of trouble and especially with Microsoft's October 2018 update for Windows 10 version 1809. Further, it's also unlikely they'll ship a version of Edge that's simply powered by the Chromium engine, but instead will probably build a specific fork of the Chromium engine designed for the specific goals they want to meet with this new version of Edge.
It's still unknown whether this new web browser will carry forward the Edge branding or adopt a completely new identity. This will mean Microsoft is ditching its own EdgeHTML. These browsers were faster and more advanced than Internet Explorer and they slowly chipped away at Microsoft's browser market share, prompting Microsoft to essentially kill IE in 2015 and replace it with Edge.
There's still no official name for the browser. For example, if Microsoft does something innovative with its fork of the Chromium engine, Google could then easily add that to Chrome.
The success of Google's Chromebook hardware and Chrome OS software wasn't an inevitability, but the ease of use they afford ended up allowing Google to carve out a niche in a very crowded PC marketplace.
The current Edge browser has been criticised since launch.
Microsoft is finally getting ready to throw in the towel and admit that it can't make web browsers, with Edge apparently getting ready to be replaced by a new browser built on Google's Chromium.
Additionally, Microsoft engineers have partnered with Google to work on developing a version of the browser that works with Windows on ARM. As to whether the interface will be radically changed or not, we do not know, but we can expect some change on that front as well.
