Apple chief executive Steve Jobs unveiled Safari versions for Windows XP or Vista operating systems and said, "We‘d like Safari‘s market share to grow. We are bringing all the Safari innovations to Windows. We‘ve got the most innovative browser in the world and the fastest browser on Windows."

According to estimates by Apple Inc., Microsoft‘s IE browser is on 78 percent of the world‘s computers while Safari, made exclusively for Apple‘s Macintosh machines until Monday, has about 5 percent of the market.

Apple will distribute Safari software as part of its iTunes online store content for the company‘s iPod.

Safari supports all modern Internet standards so users can view websites as they were meant to be seen, including HTML, CSS, JavaScript, SVG and Java.

Safari 3 for Windows requires Windows XP or Windows Vista, a minimum of 256MB of memory and a system with at least a 500MHz Intel Pentium processor.

The free public beta of Safari 3 is available immediately as a download from Apple’s web-site and is preview software licensed for use on a trial basis for a limited time.
