Microsoft today released the seventh developer preview build of its Windows Internet Explorer 9 browser. The new preview build, includes new demos, including HTML5 Galactic, Shakespeare's Tag Cloud and an HTML5 Sudoku Solver game. The preview -- unlike the beta release -- doesn't include the new user interface.

Microsoft's claiming the latest preview build includes tweaks affecting positively its JavaScript performance. Microsoft's also claiming the latest IE 9 preview is the fastest browser as measured by the SunSpider benchmark. It sounds like Mozilla is disputing Microsoft's claims on that front, however.

Microsoft also said that "13 million people have downloaded the IE 9 test builds" since the company first made its browser available to testers in March, 2010.

Here's a video of changes in action:
