Internet Explorer Vista  9.0 Vista
IE9 is designed to enable a more immersive, more beautiful Web experience. The new version of IE takes advantage of the power of modern Windows PC hardware to improve all-around Web browsing performance. It is the only browser with hardware-accelerated HTML5 spanning all graphics, text, audio and video.
IE9 harnesses the power of the Graphics Processing Unit (GPU), unlocking 90 percent of the PC’s power that went previously untapped by Web browsers. Without hardware acceleration, browsers only use about 10% of the processing power your PC has to offer. IE9 unlocks that other 90%. IE9 can tap into your graphics processor via Windows to harness the full potential of your PC.
IE9 features a simplified yet enhanced interface to put the focus on websites. The address bar and search bar have been combined into the One Box. Tabs stack along the very top and the entire frame is significantly slimmer, thereby giving you more room for the looking at content.
IE9 has HTML5 support to allow developers to write the same markup. With extensive support for HTML5, SVG, Geolocation, CSS3, and DOM, developers have a new set of capabilities with IE9.
This is the download for Windows Vista (32-bit).
