Microsoft launched Internet Explorer 10 first for Windows 8 and Windows RT. In doing so, it was also trying to get away from the third party plug-in model for web browsers. However, the Modern version of IE10 in Windows 8, as well as both the Modern and desktop version of IE 10 in Windows RT, can still run Flash-based websites without a plug-in.
That's the good news. The bad news is that domains that hosts Flash websites must also be compatible with the Flash support in Windows 8 and RT versions of IE10 in order for them to display correctly on the browser (the desktop version of IE10 in Windows 8 has no such issues).
ZDNet.com reports that over 4,300 domains are now listed on Microsoft's Compatibility View List for IE10 Flash viewing. That list is growing by about 1,000 domains a month. You can check out the current list online at Microsoft's website.
Websites owners and/or designers who have Flash-based domains that they want to add to the list can submit their sites to Microsoft. A regular web surfer who encounters a Flash site that doesn't run on IE10 in Windows 8 or RT might have to email the website owner directly and ask him or her to submit their site for inclusion in Microsoft's Compatibility View List.
