Howto remove powershell and server manager from taskbar in Windows 2008

We are running Windows 2008 Terminal Server.
I am trying to control the icons created on the taskbar when a new terminal server profile is created.
at the moment all users get Server Manager and Power Shell in the taskbar.
I want that removed and at the same time deny users to run Powershell from the search functions.

How to I control the icons created in taskbar?
How to I prevent the users to run PowerShell from the search box?

Thanks for your time
