Microsoft has unveiled the latest developer preview for IE10 - but you'll have to be running an advance version of Windows 8 to try it out.
Microsoft has been releasing developer previews of its next browser, letting users have a sneak peek at the new Internet Explorer, and giving developers a chance to prepare their sites.
The latest preview adds more support for HTML5, including video captions, as well as cross-origin resource sharing, allowing files to be safely shared across domains, such as for drag and drop file sharing. However, only people running the preview of Windows 8 will be able to see the latest features.
The move caused some confusion, with commentors on the Microsoft blog post initially unsure whether IE10 would be for Windows 8 only, after IE9 was released without support for XP.
"We will release an IE10 Beta and Release Candidate on Windows 7 prior to IE10’s general availability," Microsoft promised in the blog comments, without explaining why the preview wouldn't work on Windows 7.
Despite Microsoft making the developer preview of Windows 8 available to download here, some commentors still took issue with the set up.
"Software companies that are interested in developers to test their products are encouraged to make them available in the OS that are used on a daily base, not a pre-alpha OS that can't be used," said one user.
"The lack of a Windows 7 (or Vista for that matter) build makes this useless for testing of our web apps," said another. "Please make a standalone version available for at least Windows 7."
"The entire point of the platform preview program was to make the development of IE more transparent, but by locking new previews to a OS barely in beta state, you are pretty much killing the entire point," added another.
