Template:Use dmy dates Template:Infobox web browser Template:Infobox image Internet Explorer 10 (IE10) is a version of the Internet Explorer web browser released by Microsoft in 2012, and is the default browser in Windows 8. IE10 expands on Internet Explorer 9 functionality with regard to CSS3 support, hardware acceleration,[1] and HTML5 support.

On 12 April 2011, Microsoft released the first "IE10 Platform Preview", which runs only on Windows 7 and later.[2][3] While the second platform preview was also available for Windows 7 and later, the next four platform previews ran only on Windows 8. The first preview release came four weeks after the final release of Internet Explorer 9.[4] IE10 reached general availability on 4 September 2012 as a component of Windows Server 2012. A preview of IE10 for Windows 7 was made available for download in November 2012.

On 26 February 2013, Internet Explorer 10 was made available for download to all Windows 7 SP1 users.

On Windows 8, it is divided into two editions with different user interfaces: a Metro app that does not support plug-ins and a traditional desktop application that retains plug-in support.[5] On 64-bit computers, the Metro edition runs in 64-bit mode by default.[6] The desktop edition can be run in 64-bit mode by enabling Enhanced Protected Mode.[7]


Internet Explorer 10 was first announced on 12 April 2011 at the MIX 11 conference in Las Vegas.[8] In this conference, Microsoft showcased a demo version of Internet Explorer 10 along with a demo version of Windows 8.[9] On the same day, a Platform Preview of Internet Explorer 10 was released on the Microsoft Internet Explorer Test Drive website.[1] It only supports Windows 7; later platform previews only support Windows 8.[10] Internet Explorer 10 Platform Preview 1 supports CSS3 grid layout, CSS3 flexible box layout, CSS3 multi-column layout, CSS3 gradient, and full hardware acceleration.[11][12]

Reviewers' responses to the release of Internet Explorer 10 Platform Preview were varied; however, they noted how soon (29 days) after the release of Internet Explorer 9 Microsoft began talking about the next version. While Don Reisinger of eWeek listed his requested features for the next version, Michael Muchmore of PC Magazine tested Platform Preview 1's performance and HTML5 support with both Microsoft's and third-parties' test suites. In his test, Platform Preview 1 performed better than Internet Explorer 9 but not always better than the competing web browsers.[13][14]

On 13 September 2011, Microsoft released the developer preview of Windows 8 to general public, which came with Internet Explorer Developer Preview (the first full browser incarnation of Internet Explorer 10).[15] Although Internet Explorer is the last major web browser – among Mozilla Firefox, Google Chrome, Opera, and Safari – to support spell checking, it is the first desktop browser on Windows to support autocorrection.[16][17][18][19]

Internet Explorer 10 was released to manufacturing along with Windows 8 and Windows Server 2012. The latter reached general availability on 4 September 2012[20] while the former reached general availability on 26 October 2012. A preview of Internet Explorer 10 for Windows 7 and Windows Server 2008 R2 was released on 13 November 2012.[21][22] It is not compatible with previous versions of Windows.[23]

New featuresEdit

Adobe Flash integrationEdit

On Windows 8, Internet Explorer 10 includes a built-in Adobe Flash Player.[31] Microsoft and Adobe worked together to ensure that the version of Adobe Flash included with Internet Explorer 10 does not drain the battery or impact performance in negative ways.[31] In the "Metro" version of Internet Explorer, only some of the features of Adobe Flash will be included for battery life, performance and security purposes.[32] Some features that do not work well with touch have also been removed from the "Metro" version of Internet Explorer. However, originally, not all websites can use Adobe Flash in the "Metro" version of Internet Explorer as Microsoft and Adobe maintain a list of approved websites that are, reportedly, video content and some games.[32] In the desktop version of Internet Explorer 10, all of the features of Adobe Flash are available.[32]
On March 12, 2013 Microsoft changed this behavior from allowing only sites on a whitelist to display flash content, to allowing all sites to display flash content except those on a curated Compatibility View (CV) list (blacklist) maintained by Microsoft.[33]

User interfaceEdit

The desktop version of Internet Explorer 10 (available for Windows 7 and Windows 8) retains the user interface (UI) of Internet Explorer 9 with minor refinements, such as removing gradients. The Metro version of Internet Explorer 10 (available on Windows 8) includes a new UI, most of which is hidden so that the webpage being viewed takes up the entire screen.

The UI can be revealed by a right click of the mouse or by a swipe from the top or bottom edges of a touchscreen.[34] When the UI is shown, the tabs are listed on the top of the screen, with a small preview of the webpage on each tab. A button to add a new tab is placed in the top-right corner. At the bottom of the screen, the address bar and navigational buttons are shown. Navigational buttons include the Back button (to navigate to the previous page), the Refresh button (to reload active page), the Pin button (which create a new shortcut tile for the active page on the Start screen), and a wrench-shaped icon, which opens the only menu of IE10. It contains options such as "View on Desktop", which opens the current webpage on the desktop version of Internet Explorer 10, and "Find on page", which can find a text string (a word, phrase or arbitrary set of letters) in the active page.[34]

Flip AheadEdit

Internet Explorer 10 also introduces a new feature called Flip Ahead.[32] This works in both Metro and desktop versions of Internet Explorer 10. It allows users to move through articles that span multiple pages as well as search results and other web pages with a "next page" or similar button. This feature is turned off by default as a user's browsing history is sent to Microsoft in order to provide the feature.[31][32] According to the Windows SuperSite,[32] Microsoft has said that some sites may need to be updated to ensure it will work as intended.
