Interesting, it looks like it that Microsoft, despite earlier claims, will keep Flash in IE10. Internet Explorer 10 browser in Windows 8 will include an integrated version of the Adobe Flash plugin. Interestingly, the software giant will allow the use of Flash in Metro, but only for whitelisted websites.

In Windows 8, Microsoft's browser will come in two guises. There will be the traditional desktop browser, with its full support of plug-ins and extensions, and there will be the new Metro-style browser that will be plug-in free. But that's not quite the whole story. The browser will include an integrated and embedded version of Adobe Flash, and because this will be built-in, it won't be treated as a plug-in.

The result? Even the Metro-style browser will be able to use Flash.

Microsoft isn't opening the floodgates entirely. Use of Flash in the Metro-style browser will be limited to those sites included on a whitelist. The list is comprised of a mix of domains: video sites such as Hulu, YouTube, and Vimeo, news sites including CNN, the BBC, and Wired, and a number of entertainment and gaming sites, including Facebook and Zynga. Flash-based interactive content on these sites will work in the Metro-style browser. Flash content on other sites will require the use of the desktop browser.
