Remove Powershell Pinned Item from taskbar for all users in 2008 R2 RDS server

Question

Im trying to remove the Powershell Pinned Item from the taskbar on a 2008 RDS server. I have setup a mandatory porfile from a 2008 SP2 server (because you cannot do this in R2 any more), Check the default user pinned items folder, check the registry for powershell.exe, loaded up the NTUSER.DAT file for default to see if any thing obious was there, tried some logon scripts that are suppose to remove pinned items and posted on several forums. This has to be one of the simplest dumb things i have ever worked on , and its been about a week. So how do i remove it?
P.S.
having the user click un pinn is not a solution
yes i have checked C:\Users\Default\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch

Hi Jeramy,
The default pinned items are created the first time a user logs in. Modifying the default user profile won’t help here.
The easiest option is to set the “Remove pinned programs from the Taskbar” to disable taskbar pinned items altogether. The default pinned items won’t show up, but the user won’t be able to pin anything else either.
If you don't want to disable pinning altogether the solution is a little more complicated. One option is to remove the shortcuts “Accessories\Windows PowerShell\Windows PowerShell.lnk” and “Administrative Tools\Server Manager.lnk” from the common start menu folder. These shortcuts are copied to create the pinned items. If they aren’t present they can’t be pinned. This is not a supported option but it may work.
Another option is to use IStartMenuPinnedList::RemoveFromList in a first run script to remove the pinned items. Not sure how reliable this would be due to the timing of when the default items are added compared to when the script would run.
One other option is to use shell scripting to invoke the pin & unpin verbs on items:

This would need to be done when the user first logs in (since unpinning default items in the default user profile won't affect each new user account), but it also need to be timed after Explorer sets up the default pinned items as explained above.
Hope one of these options work for you!
