GPO pinned taskbar icons Terminal Server 2012

I would like to pin several icons to the taskbar for all the users remoting into the terminal server. I have found many sites that say the same thing...
"------------------------------------------------------------------------------------
In the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband

In the hidden TaskBar folder:
C:\Users\(user-name)\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
------------------------------------------------------------------------------------"

I have exported the taskband registry entry and used http://www.runecasters.com.au/reg2gpp-upload to convert it to HTML.
I then open my group policy that I know works and has pushed other policies out to users. I computer configuration > preferences > window settings > registry and drag and drop my xml I created from above registry entry.

I have placed my coppied pinned shortcuts to a folder that i have access and have gone to the gpo files... computer configuration > preferences > windows settings > files.
Did new > file > action update, sources = c:\sharedfolder\taskbaricons\*, destination folder = %appdata%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar.

I can see the copied files in the users %appdata%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar that I have copied, but there are no icons on the taskbar itself other than powershell and windows explorer folder.

I have tried creating new users to test to see if this works each time I try, but no luck.
