What is the Lifecycle policy for Internet Explorer?

Internet Explorer is a component of the Windows operating system and follows the Lifecycle Policy for the product on which it is installed.

Beginning January 12, 2016, only the most current version of Internet Explorer available for a supported operating system receives technical support and security updates. Products whose lifecycle ended on or before January 12, 2016 were not impacted and therefore are not represented in the table below:

IE 11 is now available via Microsoft Update Catalog, Windows Update and Windows Server Update Service (WSUS).

For customers running on an older version of Internet Explorer, we recommend customers migrate to the latest version of Edge.

Is Internet Explorer 11 the last version of Internet Explorer?

Yes, Internet Explorer 11 is the last major version of Internet Explorer. Internet Explorer 11 will continue receiving security updates and technical support for the lifecycle of the version of Windows on which it is installed.

What if my enterprise line-of-business (LOB) application has a dependency on a version of Internet Explorer that reached end of support?

Upgrading web apps to modern web standards is the best long-term solution, but customers can use the backward compatibility in Internet Explorer 11 and upgrade web apps on their own schedules. For web apps written for earlier versions of Internet Explorer, Microsoft introduced backward-compatibility features and resources to help customers upgrade to Internet Explorer 11.

In order to ease the migration to Internet Explorer 11, Enterprise Mode offers better backward compatibility and enables customers to run many legacy web applications. To help customers who have a business need for using Internet Explorer 11 with Enterprise Mode, Microsoft is committed to supporting Enterprise Mode as a feature of Internet Explorer 11 through the duration of the operating system's lifecycle.

What is the Microsoft guidance if customers run an application that depends on specific Internet Explorer runtime DLLs?

Microsoft will release security updates only for the latest version of Internet Explorer for each Windows operating system. Customers must install the latest version of Internet Explorer to update the Internet Explorer runtime DLLs, receive updates, and to remain in a supported configuration.

If a customer has turned off the Internet Explorer feature but has third-party software that uses Internet Explorer runtime DLLs, how can the Internet Explorer runtime DLLs be updated?

If customers need an update to the Internet Explorer runtime DLLs, they must install the latest version of Internet Explorer (IE 11) to update the runtime DLLs. After doing so they will continue to receive security updates.
