Previously this version of the browser was set to not play interactive Flash content by default, unless the site in question was on a Compatibility View whitelist. People who wanted to play Flash content could switch to the desktop version of Internet Explorer in Windows 8 as an alternative.
With the new update, Microsoft is switching things up. Flash will play across IE10 in Windows 8 and Windows RT unless the site in question is on a “block list.” Rob Mauceri, Internet Explorer group program manager, explains in a blog post …
Looking at our engineering experience with Flash and Windows 8 and RT, as developers improve their Flash content, the vast majority of sites with Flash content that we have tested are now compatible with the Windows experience goals. Of the thousands of domains tested for Flash compatibility to date, we have found fewer than 4% are still incompatible, in the most part because the core site experience requires other ActiveX controls in addition to Flash. With Windows 8 in the hands of customers and developers, we listened to feedback around the experience of Web sites with Flash.
The update is slated to roll out starting tomorrow.
