What makes Internet Explorer 9 different is that it pushes itself into the background and is tightly integrated with the company's Windows operating system and Bing search engine. It currently is in beta version.
Microsoft also is promising a faster, more secure version of its new browser, one that will support evolving technologies, such HTML5.
HTML5, which is currently under development, will include video playback and other graphics-intensive features that, in the past, could only be done by adding third-party software.
With Internet Explorer 9, the rendering of graphics and text has shifted to the graphics card from the CPU, accelerating speed and visuals.
"This is going to make the Windows platform more attractive, and Microsoft hopes, help stop people from leaking away to other browsers," said Dean Hachamovitch, general manager for Internet Explorer.
Internet Explorer has been the market leader for years and still holds a 51 percent share, according to StatCounter, but it has been losing share to Mozilla's Firefox and Google's Chrome, which compare to 31 percent and 11 percent respectively.
Apple Inc's Safari and Opera Software's browser had about 4 percent and 2 percent.
