Internet Explorer has been designed to make everyday tasks easier, provide dynamic security protection and improve the development platform and manageability. End user improvements include a streamlined interface, tabbed browsing, printing advances, improved search functionality, instant feeds (RSS), dynamic security protection, and more. Internet Explorer provides improved navigation through tabbed browsing, web search right from the toolbar, advanced printing, easy discovery, reading and subscription to RSS feeds, and much more. It also provides security through a robust new architecture, security features that help defend against malicious software, and new ways to better protect against the theft of personal data from fraudulent websites. The Platform Preview is an early look at the IE platform so some features are incomplete, some may change, and some may be added.

Internet Explorer Platform Preview is released periodically to give web developers, designers, and enthusiasts an advanced look at what’s to come in the next major release of Internet Explorer. It is not intended to be your daily browser, and in fact will not replace the version of Internet Explorer you have installed on your computer. The binaries that ship in the Platform Preview Build package do not replace system binaries; instead, they are placed in an iepreview.exe.local folder under the Internet Explorer Platform Preview path.
By default, pages are rendered in Internet Explorer Platform Preview with the latest rendering engine. However, if the page’s markup instructs the browser (via an “X-UA-Compatible” meta tag, a custom HTTP header from the web server, a !DOCTYPE declaration, or a combination of the three) to display it in an older document compatibility mode (for instance, IE9 mode, EmulateIE7 mode, “quirks” mode, and so on), Internet Explorer Platform Preview displays the page in that compatibility mode. (For more information about compatibility modes, see Defining Document Compatibility on MSDN.)
Internet Explorer Platform Preview must be in ”IE10 Standards Mode” to correctly display webpages that take advantage of the new features described in this document. The best way to ensure that Internet Explorer Platform Preview renders your webpages using the latest rendering engine is to include the following !DOCTYPE declaration at the beginning of the page’s HTML:
In addition, do not use an “X-UA-Compatible” meta tag on the page or send a custom HTTP header from the web server. To force a webpage you are viewing in Internet Explorer Platform Preview into a particular document compatibility mode, on the Debug menu, click the corresponding Force … Document Mode selection, or use its keyboard shortcut.
Compatibility View is a display mode within Internet Explorer 8 and later that displays webpages as if they were viewed by an earlier version of the browser. The Compatibility View List contains a number of websites known to have problems when viewed in the latest document mode of Internet Explorer; when Internet Explorer opens a webpage from a site on the Compatibility View List, it automatically displays the page in a way that allows it to be viewed correctly.
Internet Explorer Platform Preview has a smaller, targeted Compatibility View List. This ensures that you have a compatible experience with the top sites that matter to you most. You can see the list of sites on the Internet Explorer Platform Preview Compatibility View List by navigating to the following path on your computer: C:\Program Files\Internet Explorer Platform Preview\iecompatdata.xml
If your computer is running a 64-bit version of Windows 7, the Internet Explorer Platform Preview folder will be located inside the Program Files (x86) folder.
