microsoft project spartan, the new Windows browser is to replace Internet Explorer


Last month Microsoft announced that they are discontinuing development of the nefarious Internet Explorer.

The last browser in the series is IE 11, which will be replaced by Project Spartan in the upcoming Windows 10. Spartan is claimed not to use any of IE code at all, and its GUI is radically different as well. Project Spartan evolved from a branch of Internet Explorer that never became what we know as IE11. Spartan doesn’t use webkit like Safari, Chrome and Opera and its way of rendering pages is very similar to Internet Explorer. Essentially Project Spartan is a Windows 10 app that can be resized (to a certain extent), minimized and closed with good old Windows buttons, but of such huge size that it demands a bigger cursor. A big disadvantage of Spartan and other Windows 10 apps is that they cannot be started by a built-in administrator. Apparently IT admins will have to use some other browser or create a special administrative account that is not built-in in Active Directory.

All other bugs will hopefully be gone by the time Microsoft releases Windows 10 in Fall 2015. If you haven’t tested a beta of Windows 10 with the latest build that contains Project Spartan, it’s very simple to download from Microsoft and install it on a virtual machine or, if you’re feeling lucky, alongside your current OS.
