Microsoft announced in an IEBlog post that the newest update to the Internet Explorer 10 in the modern tile-UI on Windows 8 and Windows RT will allow Adobe Flash content to run by default. Earlier, the modern UI version of the IE browser did not run interactive Flash out of the box unless the site hosting that content was on a Compatibility View whitelist. Most of the sites having Flash content have been under test for the last couple of months, for compatibility with the touch-based modern UI and also battery life and performance. Barring the 4 per cent of websites that are still incompatible with Windows 8’s touch experience and depend on other plug-ins whose Flash content will be blocked, all other sites having Flash on board will now run within the IE 10 browser.

Microsoft has worked with Adobe to include a version of Flash which is optimised for touch, performance, security and battery life. They have also posted this document on MSDN for developers building sites with Flash content. It has pointers on best practises to guide and help developers, designers and content publishers. It goes into the more technical details about the criteria used to places sites on theb lock list and how developers can test their content in the immersive IE browser so as to take their site of the blocked list and make it compatible with the touch experience on Windows 8 and RT.
