Starting January 15, 2020, the version of Microsoft Edge based on the Chromium engine is expected to release and begin rolling out to devices running Windows 10 through Windows Update, replacing the legacy version of the browser.
However, if for some reason, you prefer to continue using the old version, Microsoft has published a documentation page explaining that after the installation of the Chromium version of Edge, the legacy version will be hidden from the user rather than removed. This means that you can get the Group Policy Editor to re-enable the browser to run it alongside the Chromium version of Edge.
In this guide, you’ll learn the steps to enable the legacy version of Microsoft Edge when the new Chromium version installs automatically through Windows Update.
How to enable legacy version of Microsoft Edge
To enable the legacy version of Microsoft Edge when the new Chromium version installs automatically, use these steps:
Search for gpedit and click the top result to open the Group Policy Editor app.
Browse the following path:
Computer Configuration > Administrative Templates > Microsoft Edge Update > Applications
On the right side, double-click the Allow Microsoft Edge Side by Side browser experience policy.
Select the Enabled option.
Click the Apply button.
Click the OK button.
Once you complete the steps, you’ll be able to run the older version and the new version based on the Chromium engine side by side.
Although Microsoft recommends to change this settings before the rollout of Chromium Edge, at the time of this writing, the “Microsoft Edge Update” settings may or may not be available in the Group Policy Editor.
