Windows server 2008 and vista now use an XML based administrative template structure which is now language and version agnostic. If you ever update a template within a GPO it’s only shown in that GPO. Now we have an ability to set up and use a Central repository for your ADMX based templates. This has to be created manually which kinda stinks, and also updated manually. So if you get a newer version of an ADMX file you’ll need to copy it to this admin created location. Once done though, all GPO’s will pull from the updated copy. Below is a link on how to do so, great video too!
