I'm just finishing up building a new PC with Windows 8 Pro 64-bit, and I noticed that when I started Windows Media Player 12, a Vista Home PC with Windows Media Center on the network displays a notification in the system tray "Windows Media Player found: <Win8-PC-Name>."

If I open that, I get a dialog with title "Windows Media Player Library Sharing" and the question "Do you want to allow this device to play content from your Windows Media Player library?  You can customize the music, pictures, and video to share."

Below that there is the Windows 8 PC name beside an icon representing it, and to the right of that a Sharing Settings button.

Below that there is a check-box to Disable Future Notifications.

In the lower right corner there are Allow and Deny buttons.

Of course there is the option to Disable future notifications on this Vista PC, but I don't want the Win 8 machine to broadcast/expose this information over the network.  Can I cleanly disable this on the Win 8 PC?

More info: The Win 8 machine, for the sake of acting as a specific-purpose file server, has the network connection configured with Sharing turned on, with the Private network profile in its default settings, and among the All Networks settings, Media Streaming is not turned on.

Hi,

Please turn off Media Steaming on Windows 8. You can refer to this article.
