Spartan, on the other hand, will still be based on Microsoft's Chakra JavaScript engine and Microsoft's Trident rendering engine, so similar performance to that in Internet Explorer is likely to be offered.īut what's entirely new is the functionality of the browser. Microsoft's plan is as simple as it could be: the company hopes that, by offering two different browsers, users would also be provided with a new application that can easily compete with Google Chrome and Mozilla Firefox and, at the same time, have Internet Explorer in case of compatibility issues with company apps or services. This isn't the first time that we're hearing about Spartan and it's worth knowing that at this point it's still a codename, but it appears that Microsoft is going forward with its plans to develop a new browser and this could see daylight in Windows 10 in fall 2015. Windows 10 is very likely to ship with a new version of Internet Explorer, intuitively called Internet Explorer 12, but it appears that Microsoft is also preparing a little bit of something for those who want to get Google Chrome and Mozilla Firefox-like performance on their desktops.Īccording to reports, Microsoft might actually introduce two different browsers in Windows 10, so in addition to Internet Explorer 12, PCs running this new version of the operating system could also get what's currently known as Spartan.
