One of the new features of Internet Explorer 10 in Windows 8 is that Microsoft integrated Adobe's Flash Player natively into the start screen version of the web browser. This native integration, much like Google does when it comes to the company's Chrome browser enabled Microsoft to integrate Flash in a way that it is technical no longer a plugin that needs to be loaded from external sources. By doing so, Microsoft bypassed the operating system's limitation on the start screen that would prevent the Flash plugin from being loaded otherwise.
The company made the decision to limit Flash contents to a list of whitelisted websites. If the site was on the list, Flash would run just fine, if the site was not on it, Flash would not be loaded. It was not really difficult to edit the site list and many users did so that used the app version of Internet Explorer 10.
Today Microsoft announced that it made the decision to change that behavior in Windows 8. Instead of using a whitelist approach, Microsoft from tomorrow's patch day on will use a blacklist approach instead. This means that Internet Explorer 10 will support Flash on all websites except for those that are on Microsoft's compatibility view list.
|Windows 8||Windows RT|
|Immersive IE||Enabled unless on CV list||Enabled unless on CV list|
|Desktop IE||Enabled for all sites||Enabled unless on CV list|
It needs to be noted that this affects only Flash in the app version of Internet Explorer 10, and not Flash on the desktop in Windows 8 or Windows 8 Pro. That version of Flash still needs to be installed separately and will run on all sites automatically.
Microsoft notes that the update will be made available via Windows Update tomorrow with this month's Patch Tuesday.
You are probably wondering why Microsoft made the decision to make a 180° degree turn in regards to Flash in Windows 8. The reason that Microsoft provides us with is that it has tested thousands of sites and discovered that only a small fraction of sites are not compatible with the Windows experience goals.
If you are asking me, it may have just realized that limiting Flash contents in IE10 is too limiting for users of the operating system. If your favorite sites do not work because of that, it is likely that users will blame Microsoft in the end and switch browsers if they can. On Windows RT though, they can't.Enjoyed the article?: Then sign-up for our free newsletter or RSS feed to kick off your day with the latest technology news and tips, or share the article with your friends and contacts on Facebook, Twitter or Google+ using the icons below.
