How to see contents of admx file

Hi, anyone knows how to see contents of admx file? I am not a AD guy. I was told you can see it on your local windows 7 computer by adding the admx file into %systemroot%PolicyDefinitions/ and then using gpedit.msc.

I tried that option but I don't see any new contents or contents from view agent, or connection broker in the Group Policy editor.

Any ideas??

Thanks
