While it might have taken Microsoft such a long time to transition from Internet Explorer to its Edge browser, the company is ready to move forward with its Chromium-based browser. Microsoft recently announced that when it releases its cumulative monthly security patch on April 13, it will take Edge's legacy version from Windows 10 machines. And those who don't have the new Edge version will receive it.
The legacy version is the browser that launched alongside Windows 10. It was based on Microsoft's EdgeHTML rendering, which the company rebuilt using Google's Chromium software and launched sometime in June 2020. It then announced a couple of months later that the Legacy Edge version wouldn't receive security updates after March 9 of this year.
