Internet Explorer 9&39's release candidate.

Microsoft says the release candidate for Internet Explorer 9 has been downloaded more than 2 million times since its release late last week.

Microsoft first released the software to the public last Thursday, after a five-month beta run with a total download count that topped 25 million. Later this month the company will offer an upgrade through the Windows Update software to those beta users who have not yet updated to the release candidate.

Included in this new version of the browser software are some 2,000 changes made since the last beta. The build also includes two new security and privacy features: tracking protection, and ActiveX filtering, alongside performance and UI enhancements, which you can read more about here.
