Microsoft today confirmed that Internet Explorer 11 (IE11), which will be available with Windows 8.1 update, will be also ported to Windows 7. However, Microsoft declined to say when the new web browser will be available for Windows 7.

The announcement was made during a Wednesday session at the company's BUILD developers conference.

A beta version of IE11 was released on Wednesday as part of the Windows 8.1 public preview.

New features in IE11 include an improvement in touch responsiveness, live site tiles that display information from websites on the Start Screen, and support for the open-source WebGL 3-D graphics acceleration standard.
