Always Show Cast Media Icon on Toolbar in Microsoft Edge

You can make the cast icon always show on toolbar for your user or for all user accounts in Windows. By default the cast media button doesn't appear on the toolbar in Microsoft Edge unless you are casting.

If you are not familiar with Miracast, it is a wireless display standard that allows mirroring your PC, laptop, or smartphone's screen to an external screen like a TV over Wi-Fi. These days it is less popular than Chromecast.

The Edge browser supports media casting to any DLNA or Miracast-enabled devices on your local network. Media casting is supported by plenty of modern TVs, and other popular devices like Amazon Fire TV. Note that implementation in Edge does not support Google’s Chromecast, but overall the purpose is similar even though Miracast is about screen mirroring via a Wi-Fi Direct network while Chromecast streams the media from the internet.
