In August of 2020, Microsoft announced that as of March 9, 2021 they would no longer provide security updates for their Edge Legacy web browser: the browser that launched with the Windows 10 introduction.
And starting April 13, in the form of a security update, Microsoft will uninstall the Edge Legacy browser and automatically install their new Microsoft Edge.
The new Edge is based on the Chromium open-sourced browser project that other companies like Google currently utilize for their Google Chrome browser. The idea behind the Chromium project is to assist in making browsing the internet faster and more secure.
With the new update to the browser, Microsoft has stated that any apps or sites created to work with Edge Legacy will still be functional in the new Edge. Microsoft has also added an “Internet Explorer mode” allowing users who rely on business critical legacy sites to utilize the new browser and the greater security it provides. Rather than switching between Internet Explorer for one purpose and back to your default browser for another, you’ll theoretically be able to stay in one browser for all your needs.
For a large number of users that have either already updated Edge or switched to an alternate browser, this change may go unnoticed. But for those that are still using the old Edge, expect to see the browser replaced mid-Spring.
