Microsoft has officially introduced its new 'Project Spartan' power browser for Windows 10, announcing exciting features and functionality all around.

On Wednesday, Jan. 21, Microsoft held its Windows 10 event to offer more details regarding the next major version of its operating system. Amid a number of neat announcements, Microsoft's new browser is shaping up as one of the highlights of the new OS.

The company will not ditch the famous-infamous Internet Explorer, as the two browsers will coexist in Windows 10. While Internet Explorer has been losing ground, however, Spartan is expected to be the preferred choice among consumers.

Project Spartan aims to deliver a browser that's faster and can easily handle modern web-programming standards, while putting content front and center. As previously rumored, the new browser will also bring Cortana to the desktop, allowing consumers to interact with their device through Microsoft's much-touted digital assistant. Moreover, Project Spartan will also allow users to annotate web pages with a stylus or mouse, as well as share content through email and social media or save it to the cloud.

"A new web experience for Windows 10 - Code-named 'Project Spartan,' the next generation browser was built with greater interoperability, reliability and discoverability, with a new look and feel built just for Windows 10," Microsoft touts in a new post on the Windows blog. "Advanced features include the ability to annotate by keyboard or pen directly on the webpage and easily share with friends, a reading view that is distraction free, displaying the article in a simplified layout for a great reading experience for Web articles online and offline, and the integration of Cortana for finding and doing things online faster."

Microsoft has not explained the exact relationship between Internet Explorer and Spartan, but it's clear that both browsers will be available in Windows 10. At the same time, Project Spartan will also be available on mobile devices, as Windows 10 aims to unify Microsoft's platforms and bring the experience across all form factors. As an increasing number of consumers now do their browsing on smartphones and tablets, having Spartan on mobile should help Microsoft better compete against rivals.
