Not too long ago we've seen images of build 10009 of the Windows 10 Technical Preview leak on the web.
The same people group that released the last set of images have now released more images that show a rather interesting new feature that is present in build 10009. The screenshots show Microsoft's Project Spartan web browser running on a Windows build that was compiled at the end of January, which means Insiders might get a chance to play with it sooner than expected.
The new web browser is going to replace Internet Explorer as the default in Windows 10, and will have a plethora of new features, such as Cortana integration, annotation capabilities, a reading list, and proper extension support.
Spartan is not just a visual redesign, it's also powered by an entirely new engine created specifically for the modern web called EdgeHTML, which is no longer bloated with legacy code. Its name is not final, but a lot of people want Microsoft to keep calling it 'Spartan'.
