How to disable the Cast media feature in Microsoft Edge

You can disable the cast media feature in Microsoft Edge and the cast toolbar button for all users if you want to prevent them from broadcasting media content to other devices on the local network.

The Microsoft Edge browser has a built-in function for broadcasting media files to other DLNA-compatible devices, including computers, TVs and other modern gadgets, located within the same network. You can stream videos, photos, music, or even regular web pages. If you don’t need this feature or want to disable it for some reason, this tutorial will show you how to disable the cast media feature in Microsoft Edge.

You can access the Cast button in the context menu (right mouse click on the page), as well as in the main browser menu (the button with three dots in the upper right corner). When you turn on Cast, its button also appears on the browser toolbar.

To completely disable this option, you need to apply a Group Policy specially supported by the Edge browser. It is worth noting that when you define any of the Edge Group Policies, a small notification will appear in the browser’s menu and in Settings stating that Edge is managed by your organization.

Please be aware that following this instruction will completely disable the Cast (media streaming feature) in your Edge browser.

Finally, we note that in order to perform the actions described below, you need an Administrator account.
