The GPO seems to be set right, everything looks right, but it just does not work !

The user right clicks, pin to task bar and it does nothing ?

But if I go to the app data and delete the quicklaunch folder it works ?!? from the user area.

User reboots and the icon is in the task bar, but it wont let you add any more, if you un pin the pinned item, it won't let you re add it.

Only way to fix it, is to delete the above folder and do it again ?!?!

I have a redirected start menu to the C drive, a shared desktop in the Netlogon folder

I have tried this with app data redirected and left local, and same results
