It was back in January that Microsoft showed off its long-awaited replacement for Internet Explorer, currently named "Project Spartan." The new browser is designed to be light, nimble and secure, with the company stressing how deeply Cortana, Microsoft's virtual assistant, is baked into the software. Now, thanks to WinBeta, we've gotten the first sense of how that'll work out in the real world. For instance, visit the homepage of a restaurant and the blue circle in the address bar will bounce to advise you that more information is available. In addition, you can highlight and right-click a word to define it, and typing in keywords in the address bar -- such as weather -- will bring up relevant information. The video is short, but you can expect plenty more like that when the previews of Windows 10 (with Spartan) arrive at the end of the month.
