Internet Explorer, the Microsoft browser that is almost 20 years old, is to be killed off and replaced by a new operating system. Microsoft has confirmed that its new browser, code-named Project Spartan, that is due to be unveiled later this year, will not use the familiar Internet Explorer name. 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.
