I wrote already that icon [TV] Samsung UE48HU8500 disappeared in Charms menu -> PC and Devices -> Devices after failing Miracast session so at this point there is nothing to remove. However new device Miracast display devices - [TV] Samsung UE48HU8500 appears in the Device Manager with an exclamation in a yellow triangle that indicates driver installation failure. Also grayed (disabled) icon [TV] Samsung UE48HU8500 appears in Settings -> Devices and printers .I have to constantly remove subj from these places after failing Miracast session. Otherwise the system does not can find a new device in the Charms menu ->PC and Devices -> Devices during new attempts establishing Miracast session.
But these manipulations do not lead positive results.
Attempts establishing Miracast session are finished unsuccessful driver installation for Miracast displaydevice - [TV] Samsung UE48HU8500.
