Internet Explorer (IE) 11 is the last major version of Internet Explorer. Beginning June 15, 2022, the Internet Explorer 11 desktop app will no longer be supported on certain versions of Windows 10.
Microsoft encourages customers to switch to Microsoft Edge
, which provides support for older and
modern websites and apps. If your organization needs support for older browsers, you should set up IE mode in Microsoft Edge as soon as possible. To continue using older IE-based websites and apps in Windows 10 and Windows 11, you must configure your affected websites and apps to open in Microsoft Edge using Internet Explorer mode. Internet Explorer mode in Microsoft Edge enables backward compatibility and is supported until at least 2029.
