After the redirection phase completes, IE will be permanently disabled through a future Windows Update on all devices with Windows platforms that are in-scope for IE retirement. The second phase of retirement is the Windows Update phase.
During the first phase-the redirection phase-devices will be progressively redirected from IE to Microsoft Edge over the following months. Today, the Internet Explorer (IE) 11 desktop application goes out of support and will be retired for certain versions of Windows 10.
