Support for ActiveX has been discontinued in Microsoft Edge, and that includes removing support for Silverlight. The reasons for this have been discussed in previous blogs and include the emergence of viable and secure media solutions based on HTML5 extensions. Microsoft continues to support Silverlight, and Silverlight out-of-browser apps can continue to use it. Silverlight will also continue to be supported in Internet Explorer 11, so sites continue to have Silverlight options in Windows 10. At the same time, we encourage companies that are using Silverlight for media to begin the transition to DASH/MSE/CENC/EME based designs and to follow a single, DRM-interoperable encoding work flow enabled by CENC. This represents the most broadly interoperable solution across browsers, platforms, content and devices going forward.
Edge への QA がありますね。
Microsoft Edge has been designed and built to showcase Windows 10 features like Cortana, and is built on top of the Universal Windows Platform. We don't have any plans to bring Microsoft Edge to Windows 7 or Windows 8.1 at this time.
Windows 7,8.1 はサポートなしとのこと。そりゃそうだよね。
Yes, Adobe Flash is supported as a built-in feature of Microsoft Edge. We continue to work closely in partnership with Adobe to provide this version of Flash, which we support and service via Windows Update.
Microsoft Edge supports viewing PDFs and Adobe Flash as built-in features, but does not support any third-party installable plug-ins. This allows us to build a more secure and more reliable browser to make the Web a safer experience for everyone. We’re working on a new, modern extensibility model for Microsoft Edge in a future update.
PDF のビューワーもサポートする。それ以外の QA も呼んでみてください。
