Microsoft Edge has Internet Explorer mode (“IE mode”) built in, so you can access those legacy Internet Explorer-based websites and applications straight from Microsoft Edge. With Microsoft Edge capable of assuming this responsibility and more, the Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022, for certain versions of Windows 10.

Note: This retirement does not affect in-market Windows 10 LTSC or Server Internet Explorer 11 desktop applications. It also does not affect the MSHTML (Trident) engine. For a full list of what is in scope for this announcement, and for other technical questions, please see our FAQ.
