Last week I noticed on http://get.adobe.com/flashplayer/, when viewed in Metro IE10 that there was instructions on how to get your site able to run Flash in Metro's version of IE10. The link provided, however, didn't include said instructions. So my first question is: how do I get a site included on that list?
Secondly, the page currenetly reads "This content requires a newer version of the Flash Player. Please download and install the latest version of Flash Player from the Windows Update site before continuing."
However, no updates are available from Windows Update.
Are you speaking about the Compatibility View list in Internet Explorer 10? To view your content in Modern IE mode, the content needs to be in the Compatibility View list. The following artcile from Microsoft has the details: http://msdn.microsoft.com/en-us/library/ie/jj193557(v=vs.85).aspx
I think the Windows update mechanism is not in place yet.
