Sftdcc.exe does not timeout after closure of application launched via GP in kiosk mode.

Question

We are configuring a group policy to launch an application upon login to the Remote Desktop Server.
The following group policy object is configured;
User Configuration\Policies\Administrative Templates\Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment
By default, Remote Desktop Services sessions provide access to the full Windows desktop, unless otherwise specified with this setting, by the server administrator, or by the user
in configuring the client connection. Enabling this setting overrides the "Start Program" settings set by the server administrator or user. The Start menu and Windows Desktop are not displayed, and when the user exits the program the session is automatically
logged off.
Start a program on connection - Enabled 
Program path and file name "C:\Program Files (x86)\Microsoft Application Virtualization Client\sfttray.exe" /launch "universe 1"
Working Directory
This has also been tested running Notepad.exe
The application launches successfully.
Upon exiting the application the App-V client shuts the application down successfully but the RDS session does not log the user out or end the RDS session. The sftdcc.exe process
does not timeout.
Using Task Manager to end the sftdcc.exe process initiates the logout process.
Is the following still valid for Server 2008 R2 and App-V v4.6 x64?
Can’t find any reference to it via;

How To Deal With Microsoft App-V sftdcc.exe when Sessions are not closed properly After installing Microsoft App-V for terminal servers
users sessions are not closed properly after logoff. You can see through the Citrix Advanced Management Console that the session is in disconnected state and sftdcc.exe is running in the user session.
There are two registry keys you can set for this problem to disappear:
HKEY_LOCAL_MACHINE\Software\Softricity\SoftGrid Client\CurrentVersion\Configuration\
Value Name: DCCSeamlessTimeout
Type: REG_DWORD
String: 0
 I have tried adding the DCCSeamlessTimeout to the HKLM\Software\Wow6432Node\Microsoft\Softgrid\4.5\Client\Configuration
but this does not have any effect.

Updates on this issue.
if you are running window server 2008 R2 install this hot fix:
KB2815716-v2-x64
then add this registry values:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs" /v sftdcc.exe /t REG_DWORD /d 0
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs" /v splwow64.exe /t REG_DWORD /d 0
then reboot, and that will fix it.
if you are running 2012 r2, then only add the registry values and reboot.
