Are you referring to the 'toast' popup that shows the artist, title and album of the current song, and contains a seekbar? To prevent that from popping up, open the Start Menu, type regeditin the Search field, and press Enter. In Regedit, navigate to HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences , create a DWORDvalue named DeskbandFlyoutTimeout , and set it to 0x0 .
