Most home users may have no need for IE Mode, but companies may, as certain applications and services may have been created exclusively for Internet Explorer.

IE Mode ensures that Internet Explorer specific content can still be loaded. Since Edge is based on Chromium, it does not support Internet Explorer technologies. The browser supports a legacy mode, called IE Mode, which companies and users may utilize to load IE-specific content in Microsoft Edge. Microsoft Edge will be the sole Microsoft browser going forward.

The Internet Explorer files will not be removed from devices after support ends, as these are required for IE Mode. The desktop application won't start anymore after it is retired and Microsoft Edge will be loaded instead. Internet Explorer 11 will be retired on Jaccording to Microsoft.
