Consider the following scenario:
You connect to a Remote Desktop Protocol (RDP) session by using Mstsc.exe.
You start Windows Internet Explorer 11 or Windows Internet Explorer 10 in Kiosk mode.
You disconnect from the RDP session, reestablish the connection, and then start Internet Explorer in Kiosk mode again.
In this scenario, Internet Explorer freezes, and a black bar is displayed at the top of the screen.
To resolve this issue, install the most recent cumulative security update for Internet Explorer. To do this, go to Microsoft Update. Additionally, see the technical information about the most recent cumulative security update for Internet Explorer.
Note This update was first included in the August 2015 security update for Internet Explorer (MS15-079).
Microsoft is researching this problem and will post more information in this article when the information becomes available.
