It is worth mentioning that if you are using Roaming profiles this will not work very well, especially if you are redirecting app data, or deleting profiles when users log off of machines.

Users will suddenly lose anything they have pinned as it doesn't sit within the normal areas of the appdata that get redirected.

The way that i have overcome this is by using a logon/logoff script to backup the users pinned items and to restore them when they log on.

Logon Script

DEL /F /S /Q /A "%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar\*"

copy /y "\\nas01\%username%\TaskbarPinnedItems" "%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar"

REG DELETE HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband /F

REG IMPORT \\nas01\%username%\TaskbarPinnedItems\Taskbar-Pinned-Items-Backup.reg

log off script

mkdir "\\nas01\%username%\TaskbarPinnedItems"

copy /y "%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar" "\\nas01\%username%\TaskbarPinnedItems"

REG EXPORT HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband \\nas01\%username%\TaskbarPinnedItems\Taskbar-Pinned-Items-Backup.reg /y

Any one using this will have to update the script to work in their environment, if someone has a better solution please comment and let me know!
