These is a question. And MS give the following answer:
“Internet Explorer provides an add-on–free experience, so browser plugins don’t load and any dependent content isn’t displayed. However, Internet Explorer for the desktop does support browser plugins, including ActiveX controls such as Adobe Flash and Microsoft Silverlight. For more information, see Browsing Without Plug-ins on IEBlog. ”

So should we take it as NO?
And what does it mean “Internet Explorer for the desktop”?
As a Windows Store app, i.e. such as you might have on a tablet device, it runs in plug-in free mode. But on a PC, it doesn’t unless you set it to. So Silverlight and other plugins are still fully supported in IE10 for a PC.
