Remove Cast to Device from Context Menu in Windows 10

Cast to Device is a feature Windows 10 got from previous Windows releases. Earlier known as Play To, it allows the user to stream media content from your Windows 10 device to another receiver device with Miracast or DLNA support. Explorer provides a context menu item called Cast to Device for folders and media files. If you found no use for this feature, you might want to get rid of the context menu command. Here is how it can be done.

In Windows 10, the Cast to Device feature is implemented via a special shell extension. If you block it from loading, this will remove the context menu item from File Explorer. This can be done with a simple Registry tweak.

Remove Cast to Device from Context Menu in Windows 10

1. Open Registry Editor.
2. Go to the following Registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked

   Tip: see How to jump to the desired registry key with one click.
   If you don't have such a key, then just create it. In my setup, the subkey "Blocked" did not exist, so I created it myself.

3. Create a new string value here named {7AD84985-87B4-4a16-BE58-8B72A5B390F7}. Leave its data value empty as shown below:
4. Now, restart the Explorer shell or sign out and sign in back to your user account.

The Cast to Device context menu item will disappear. You are done.
