Internet Explorer has been a cornerstone of Windows ever since 1995, but it looks like Microsoft is ready to leave its venerable (if sometimes infamous) web browser by the wayside. ZDNetunderstands that a previously rumored overhaul to Internet Explorer for Windows 10, nicknamed Spartan, is actually a brand new creation. It would still use the company's own web engines, but it would be far more "light-weight" and, if you believe earlier leaks, behave more like Chrome or Firefox. The break is reportedly sharp enough that the future Windows version will keep Internet Explorer 11 around in case you need it for certain apps or features.
