Windows 10's new browser is now called "Microsoft Edge," a much better name than the "Project Spartan" codename it was previously known by.
Edge is spartan, though. The new browser is noticeably trimmer than Internet Explorer, without the sea of menu options and bells and whistles. Settings are mostly straightforward and super-slimmed down -- just the bare essentials.
Most importantly, Edge is noticeably fast. It runs a new engine that Microsoft says it built from scratch. That appears to have paid off. Spartan loads complex websites quickly, and there's practically no delay when playing videos.
It also supports extensions and applications, offline reading and reading mode, lets you write directly on websites, and integrates Cortana to give you directions to restaurants and other locations.
