Windows Home Premium does not contain any of the Windows group policy provisions or tools. However, it is not clear that this item is part of Windows. The fact that you have a policy file at all seems to indicate that this is a Java item, and the link seemed to indicate the same. It's possible that it is a developer tool and as an end user, you're not supposed to be over-riding the policies. Explore whether you can download the tool. I would start with that link.
