Internet Explorer is gone, except where it isn’t
IE was retired on 15 June. Old internal apps still need it, through Edge’s IE mode. Plan their exit.
Last Wednesday Microsoft retired Internet Explorer 11 on most versions of Windows 10. Opening it now sends you to Edge. After 27 years, that’s the end of a browser most of us were happy to forget.
Except in companies. Many still run an old intranet, an ERP screen or a government portal that only works in IE. For those, Edge has “IE mode”, which keeps the old engine alive inside Edge.
What I’d do:
- List the sites that need IE mode. Your Edge policy’s site list is a good start.
- Keep that list short and controlled through policy, not users clicking “reload in IE mode” everywhere.
- Ask each vendor for a date when their app will work in a modern browser.
- Keep Windows patched. The old engine still gets security fixes, and attackers still target it.
IE mode is a bridge, not a home. Every app that leaves it is one less old engine to worry about.
