Steve the cookie monster asked a great question during module 5 of the 6294 class. "How can i pre-seed taskbar links or pinned items. I’ve tried to "Copy profile" within the unattended.xml file, but have had no success"…
     I did some trolling of the Windows 7 forums and found a potential solution. i will have Steve test this for us and give us the results!
