Internet Explorer will still exist in some versions of Windows 10 mainly for enterprise compatibility, but the new Project Spartan will be named separately and will be the primary way for Windows 10 users to access the web. Microsoft has tried, unsuccessfully, to shake off the negative image of Internet Explorer over the past several years with a series of amusing campaigns mocking Internet Explorer 6. The ads didn’t improve the situation, and Microsoft’s former Internet Explorer chief left the company in December, signalling a new era for the browser.

A number of recent reports have suggested that Microsoft was ready to move past Internet Explorer and introduce a new browser, code-named Spartan, to the world. Now, Microsoft has made that official by announcing that Project Spartan will be the new web browsing experience for Windows 10. The new browser will feature an all-new rendering engine, but beyond that Microsoft wanted to focus on three new features, some of which we learned about earlier this year.
