Microsoft have just released a web site that allows you to search for any group policy setting. You can either do a key word search or just browse particular setting. Using a web site like this is a lot easier than having to crack open an existing Group Policy Object to see what policy settings there are available.
The URL for the site is http://gps.cloudapp.net/
I STRONGLY recommend that if you have anything to do with Group Policy then add this site to your favourites. Even better click on â€œAdd Search Connectorâ€ from the settings menu option and add it as a search provider for you to use straight from Windows 7â€¦ AWESOME!!!
I really like the â€œRegistry Viewâ€ (see below) you can select from the Tree menu option which allows you to browse all the group policy settings based on the registry key of the policy.
Note: This search tool also has all the Microsoft Office 2007 and 2010 group policy settings included.

Update: Group Policy Blog has now posted about this search engine as well at Cross post: AskDS Group Policy Search Settings in the cloud
