This is how to Enable or Disable Microsoft Edge VP9 which is in Windows 10. Microsoft Edge is a web browser that is optimized for the modern web and available on Windows 10 devices. To enable efficient compression for HD content streaming at lower bitrates. Likewise the browser supports VP9, an open source video format.
Enable or Disable Microsoft Edge VP9
Firstly the initial implementation of VP9 in Microsoft Edge will use Media Source Extensions to enable adaptive streaming. 
Secondly this was specifically designed to support websites that deliver video with VP9 in combination with other audio codecs already supported by Microsoft. Lastly these include the MP4/AAC. Likewise Microsoft plans to add support for VP9 for media tags and local playback in the future. This as well as considering support for additional audio formats like Opus. Additionally see the vp9 codec download on here as well as Kodi codecs. Likewise there is the Kodi Player troubleshooting.
Additionally this implementation of VP9 will support software decoding and, when possible, hardware decoding. However, since video decoding requires significant computation, the best experience with the software decoder will be on more powerful computers. Likewise the VP9 will initially be implemented behind an experimental flag, and a setting will be available to enable or disable VP9 support. Microsoft will continue to work with industry partners to expand hardware decoding support and evaluate support for additional audio formats.
