Questions tagged [internet-explorer-9]

Windows Internet Explorer 9 (abbreviated as IE9) is a web browser developed by Microsoft, released on 14 March 2011. It is available for Windows Vista SP2 and above, Windows Phone 7.1–7.8, and the Xbox 360. It was replaced by IE10 on Windows 8, Windows Server 2012 and Windows Phone 8.

Internet Explorer 9 supports several CSS 3 properties, embedded ICC v2 or v4 color profiles support via Windows Color System, and has improved JavaScript performance. It also features hardware-accelerated graphics rendering using Direct2D, hardware-accelerated text rendering using DirectWrite, hardware-accelerated video rendering using Media Foundation, imaging support provided by Windows Imaging Component, and high fidelity printing powered by the XPS print pipeline. IE9 also supports the HTML5 video and audio tags and the Web Open Font Format. Microsoft has released IE9 as a major out-of-band version that is not tied to the release schedule of any particular version of Windows, unlike previous versions.

The system requirements for IE9 are Windows 7, Windows Server 2008 R2, Windows Vista Service Pack 2 or Windows Server 2008 SP2 with the Platform Update. Windows XP is not supported. Both 32-bit and 64-bit builds are available.

For more information on developing for IE9, see the Internet Explorer 9 Guide for Developers.
