The problem is the policies you are using are pre windows 7, some of the configuration items still work, but some dont. The easiest way (imo - there are multiple ways) would be to make a windows 7 policy and filter it ( using WMI) so its scoped to only windows 7 clients.
to do this, get a windows 7 machine with the remote admin tools, and edit a new policy, apply it to the OU containing machines or users and use a filter for windows 7. That way you can be sure to have a policy applied that designed for the windows 7 machines.
As i said, different ways of doing it but thats how i'd manage it.
