Q: Is there any interactive website I can use to quickly see Group Policy settings for the different elements of Windows and Office?

A: Microsoft has made a great site available, hosted on Windows Azure, that offers an easy interface to view all Group Policy settings based around a related area.

Available at GPSearch, the policy tree at the site (see screen shot below) allows a policy to be selected in the Policy Tree or a search performed, and then displays details on the policy.
