Alongside the settings, it also possible to use the Group Policy Editor to configure the compatibility mode. If you have to use this compatibility mode, the version of Microsoft Edge available in the stable channel includes the “Internet Explorer compatibilities” settings to quickly enable IE Mode and a separate option to open Edge when browsing an incompatible website with Internet Explorer. The new approach loads the pages within Microsoft Edge like a regular website without using and managing multiple browsers. The feature is known as “IE Mode” and has been designed for organizations to load internal sites without using a separate browser or redesigning the site.
Alongside all the features and improvements in the roadmap for the new version of Microsoft Edge based on the Chromium engine, Microsoft includes a compatibility mode using the Internet Explorer rendering engine to load old websites.
