We are rolling out a new application that needs to be able to access
registry key values and write to them. The problem is that our users are
standard users and do not have access to the registry. I have been able to
figure out what keys the application needs access to but I am unsure how
to allow users access to these registry keys, but I believe that it can be
done via group policy

We have implemented Group Policies via Zenworks.

Any ideas would be greatly appreciated.
