Microsoft will talk about its plan for upcoming builds of Internet Explorer this week at the Professional Developers Conference -- though, it will not offer a preview of its next browser, according to CNET. It is also reported that the company is not planning to announce a move to the WebKit engine, despite speculation.

During a presentation today at the conference, chief software architect Ray Ozzie said Microsoft would make Internet Explorer the best Windows browser, but did not elaborate. Redmond is expected to offer more details during tomorrow's keynote speech, however, which will touch on some "focus areas" for the next version of IE.

Microsoft introduced the current version of Internet Explorer (IE8) in March of this year, and as of October, it held about 20% global market share. The company has struggled to move users away from IE6, which held some 23.3% of the market last month.
