Windows Internet Explorer 9 ( IE9) is the latest version of the Internet Explorer web browser from Microsoft.
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 XML Paper Specification (XPS) print pipeline.
Internet Explorer 9 also supports the HTML5 video and audio tags and the Web Open Font Format.
The system requirements for Internet Explorer 9 are Windows 7, Windows Server 2008 R2, Windows VistaService Pack 2 or Windows Server 2008 SP2 with the Platform Update. Internet Explorer 9 is the last version of Internet Explorer to be supported on Windows Vista.
Internet Explorer 9 includes significant alterations to its user interface when compared with previous versions. These include:
- Pinned Sites: Integrates with the Windows 7 taskbar to make web site experience more like an application where users may “pin” a site and then return to it later like a shortcut. In the release candidate, users can pin a site and add more homepages to that site (e.g. pin Facebook and add Twitter as another homepage to that pinned site, so it would become a social program)
- Security-enabled Download Manager: Manages file transfers and can pause and resume downloads and informs if a file may be malicious
- Enhanced Tabs and Tab Page: The new tab page can show most visited sites, and tabs are shown next to the address bar (there is an option to have a separate row, like in Internet Explorer with the feature of closing an inactive tab. Tabs can be “torn off” which means they can be dragged up and down to be moved from one IE window to another. This also ties in with the Aero Snap feature.
- Add-on Performance Advisor: Shows which third-party add-ons may be slowing down browser performance and then allows the option to disable or remove them
- Compact user interface: Includes the removal of the separate search box found in Internet Explorer 7 and 8. Also removed is the tab menu list found in Internet Explorer 8.
