Make the Start Screen yours
The Start button returns
The controversial Start button returns to Windows 8, and if you want you can almost combine it with the All Apps view to create a Start Menu of sorts. The button is simply a visual element that takes you back to the Start Screen, but you can also right click on it and access power user commands and the shutdown or restart options. Its return should help ease one of the usability complaints around Windows 8, but it does very little to change the way you have to interact with the Charms or the recently used apps with a mouse and keyboard. Fortunately the hot corners can be disabled so if you want to totally avoid the "Metro" world then it's possible to do so without third-party software now.

Search
Built-in Bing search
Search has been totally overhauled in Windows 8.1. Bing now powers the interface and underlying algorithms used to discover and fetch data from local PCs and the web. Microsoft has long been investing in desktop search, but it’s moved forward significantly in the 8.1 preview. You can simply type on the Start Screen and you’ll be able to instantly access web queries, recent searches, system settings, files, and other information. If you want to quickly launch an app then you can just type the first few letters and you’ll be presented with it. The search interface appears to favor apps over other content, but it also learns your search habits and adapts accordingly.Bing Heroes
Bing Heroes surfaces images, video, and audio content in a stylish wayPerhaps the biggest change to search here is a new hero interface powered by Bing. If you search for an artist like Rihanna you’re presented with a full-screen interface that surfaces images, video, and audio content. It’s done so in a useful but stylish way and it will even retrieve data from applications. One particularly impressive part of this search interface is that it shows web links with a thumbnail preview of the site you’re about to click on. If you want to play audio from a particular artist then it jumps straight into Xbox Music, or it will find YouTube videos from the web that are relevant.News is also presented, alongside key information from Wikipedia. The images can be expanded and viewed separately, and there’s even the option to filter them by color to find the exact image you need. Speaking of images, if you search for a location the new Search experience can even find pictures you may have taken there, surfacing them alongside web results. It’s clear Microsoft has put a lot of thought and effort into this interface, and it has paid off.
Apps
Mail and Office
Most of the Windows 8 apps are being improved, but one that’s not part of the preview is the Mail app. The company is demonstrating some of the improvements it’s working on, including drag-and-drop support, sweep (which can remove large quantities of older unwanted mail) and the ability to group social and newsletters in one place. The Mail app is clearly starting to take shape into something that’s more usable and powerful to use over on tablets and even desktops. In the preview release the improvements aren’t ready, but Microsoft tells us an updated app will ship with Windows 8.1 later this year. One thing that does work well now is Mail's ability to pop open an app, side-by-side with Mail, to quickly view a web link or attached photo.Metro Office is coming soonI also saw a brief glimpse of Windows 8-style Office applications which Microsoft is currently working on. Described as an alpha build, Microsoft was only prepared to show off a copy of PowerPoint running a presentation, but the suite should launch for Windows 8.1 tablets later this year.
Spin for better photography
Microsoft has some pretty intriguing user experiences for snapping shots and editing photos in Windows 8.1. With Photosynth, part of the Camera app, you can take a whole 360 degree photosphere — an entire room floor to ceiling — just by moving the tablet around, as if each image is filling in the pieces of a virtual jigsaw puzzle. The Photosynth software stitches them all together, and the results are surprisingly good. Meanwhile, the Photos app lets you enhance or mute colors through a different circular procedure: you drop a pin on any spot, then rotate a radial dial (which reminds me of OneNote) to adjust the intensity.Internet Explorer 11
Internet Explorer 11 largely looks the same as its IE10 counterpart. The tab interface has been moved to the bottom, and Microsoft is catching up to the competition with tab sync across Windows 8.1 devices and Windows Phone. WebGL is also supported in Internet Explorer 11, and website owners can create separate Live Tiles that can be pinned to the Start Screen to access RSS feeds.Unfortunately there are still separate desktop and Metro versions of IE11, and the tabs don't appear to keep in sync between the two. It's an odd disconnect given Microsoft's focus on cloud syncing in 8.1. IE11 will also detect phone numbers on sites so you can call them using apps like Skype, and the app fully supports the new Reading List feature that will let you bookmark web pages for later reading.
