Internet Explorer 11 desktop app retires June 15, 2022
As previously announced, the future of Internet Explorer on Windows is in Microsoft Edge. Internet Explorer mode (IE mode) provides legacy browser support within Microsoft Edge. Because of this, the Internet Explorer 11 (IE11) desktop application will be retired on June 15, 2022, for certain versions of Windows 10. This means that the IE11 desktop application will no longer be supported and afterward will redirect to Microsoft Edge if a user tries to access it. ..
