Internet Explorer 10 (IE10) is the tenth version of the Internet Explorer web browser and the successor to Internet Explorer 9. Released by Microsoft on September 4, 2012 – shortly after the completion of Windows Server 2012 – it was the default browser that shipped with Windows 8 and Windows Server 2012, and can also run on Windows 7 and Windows Server 2008 R2 at minimum.

IE10 expands on Internet Explorer 9 functionality with regard to CSS3 support, hardware acceleration,[1] and HTML5 support. 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. On 64-bit computers, the Metro edition runs in 64-bit mode by default. The desktop edition can be run in 64-bit mode by enabling Enhanced Protected Mode.[2]

History[]

Internet Explorer 10 was first announced on April 12, 2011 at the MIX 11 conference in Las Vegas.[3] In this conference, Microsoft showcased a demo version of Internet Explorer 10 along with a demo version of Windows 8.[4] On the same day, a Platform Preview of Internet Explorer 10 was released on the Microsoft Internet Explorer Test Drive website. It only supports Windows 7; later platform previews only support Windows 8. The beta and release candidate will be available for Windows 7.[5]

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 is Microsoft 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.[6][7]

On September 13, 2011, Microsoft released Windows 8 Developer Preview to the general public, which came with Internet Explorer 10 Developer Preview (the first full browser incarnation of Internet Explorer 10).[8] 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 to support auto-correct.[9][10][11][12]

On version ES5 of the ECMAScript standards conformance Test 262,[13] Internet Explorer 10 Consumer Preview scored 67/11563 (Tests To Run: 11563 | Total Tests Ran: 11563 | Pass: 11496 | Fail: 67 | Failed To Load: 0). Lower scores are better, as the figure represents the number of failed tests out of the total number of tests. This score of only 67 failed tests represented one of the best ECMAScript conformance score for all browsers on version ES5 of the test.[citation needed] Test 262 is still undergoing active development and is not yet complete. IE10 is also the first iteration of Internet Explorer to fully pass the Acid3 test.

User agent string[]
