In 18 days, Internet Explorer will turn 20 years old. But rather than celebrating with a new version, as it did for birthday number 15, Microsoft will be shoving IE away into an obscure folder with other legacy applications -- you know, like Paint. Though the browser will live on, mostly for the sake of enterprise users, it will only receive security patches going forward (read: no new features or design changes). Just as important, it will no longer be the default browser in Windows. That honor now goes to Edge, a cleaner, leaner browser that makes its debut on Win 10. Microsoft hopes that with the name change, fresh design, smarter features and improved performance, Edge will be enough to convince people to set aside whatever negative impressions they may have had of Internet Explorer.
