The latest Windows 10 build includes a preview version of the new browser. This means that the browser will be a stripped down version. Microsoft said that the browser was an internal testing version and it may contain bugs and issues. The all new Spartan browser will give users the following features :
Cortana is built-in and ready to assist: Cortana in Project Spartan is a personal assistant that helps make Web browsing easier for you, with whatever you’re trying to get done. Cortana offers help at just the right moment, based on what she knows about the Web, about you and what you might be trying to do. She remains in the background but provides additional information when you need it, making browsing easier and more efficient. Cortana in Spartan will be available in the US versions of this build, and available more broadly later. Inking and sharing so you can capture and communicate your thoughts: Everyone uses the Web routinely to share questions, thoughts, info and comments with friends and colleagues. Now with new inking capabilities, Project Spartan enables you to write or type directly on the page, comment on what’s interesting or clip what you want – then easily share this “Web Note” via mail, or a social network. Researching and collecting information from the Web is just as easy, as you can save your notes directly to OneNote. Distraction-free reading with Reading List and Reading View: Keeping up with information overload on the Web is one of the challenges that we all have to manage. Project Spartan helps with a beautiful new Reading List to collect everything you want to read, including the ability to save any webpage or PDF for convenient access later, and an integrated, distraction-free Reading View that keeps you focused on the content. A new engine for the modern Web: Project Spartan’s new rendering engine is built around the idea that the Web “just works,” while being fast, more secure and more reliable.
If you have signed up for Windows 10 Technical Preview and the fast update option, you can get the Build 10049 with the Spartan browser right away.
Microsoft has promised that Spartan will be updated at regular intervals to bring users latest features.
