Microsoft has said previously that it will keep Internet Explorer 11 as legacy code within the desktop version of Windows 10, designed to access older enterprise websites. But the company has also intimated that it will drop the Internet Explorer name. The Spartan browser comes with a brand-new rendering engine called Edge, reportedly much faster than the Trident engine that powers IE.
Mail and Calendar: The new apps integrate together, meaning that you won't have to go back and forth to the desktop to switch between email and the calendar, for example. Outlook Mail includes customizable Swipe Gestures, letting you swipe right or left to take actions like delete, flag, move, and mark as read/unread.
New Phone, Messaging apps: We'd expect the new Messaging apps to look somewhat like what we saw in Redmond in January, with the integration of Skype messaging and SMS. Unfortunately, if your phone had the January build on it (Build 9941) you'll need to roll back to Windows 8.1, then upgrade again to enable SMS.
New People app: Microsoft claims this has a new visual design, but will still keep track of all your contacts across services like Google, Facebook, and more.
New Maps app: Again, the new universal Maps app should look like what Microsoft showed off in January. Bing Maps will be plundered for its rich search results, Streetside views, and 3D imagery, and combined with navigation features. With a tap on a location, users can see the aerial view or the surrounding traffic. Rich search results are pre-populated with common search terms (e.g., "coffee") and search results yield Yelp reviews and the ability to book reservations via OpenTable.
Updated apps switcher: Microsoft reportedly has added a "four-up" view to the app switcher, so that you can now see more apps on the screen simultaneously.
