Hendrikus, the Registry CSE is pretty much the descendant of the old NT 4 policies, it has GUID {35378EAC-683F-11D2-A89A-00C04FBBCFA2} (and is listed but no settings), it is very special and not a "true" CSE to 100%, for example when you register your own CSE, you can say that it should only process if the Registry CSE successfully executed etc. But to sum up it is the CSE that is responsible for anything under Administrative Templates, i.e. ADM/ADMX. Also a number of other extensions rely on the Registry CSE, for example the Software Restriction Policy as far as I recall, that in reality adds settings that the Registry CSE will manage but from its own GPOE snap-in.

I'm not quite sure though if I understand what you both mean by "Registry CSE". I guess you mean it's not one of the CSEs listed in my GPExtensions registry key? (I'm not sure whether there is one main "registry" CSE with some additional CSE extensions, or if the "registry CSE" is just one of those/ any of those extensions we can find under HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions). I'd like to optimize our GPOs, i.e. per GPO only add settings that are processed by a single CSE. (Goal: if the GPO version is incremented, have only CSE x update its list, and not CSE y) You are right Darren: the GPExtensions list is pretty straightforward, but they only cover a small percentage of the overall settings. If the "Registry CSE" does most everything, I'm wondering if my "optimization" would make sense....

In terms of which settings are processed by which CSEs, this is not completely straightforward but, for example, most everything under Administrative Templates is processed by the Registry CSE and then the rest of the CSEs are pretty self-explanatory. But I don't think you will find a definitive list of which CSE processes every setting.

I have found a list of default Client-Side Extensions on Technet: http://technet2.microsoft.com/windowsserver/en/library/824b4758-9430-4633-8d8f-3dad0f2bf8391033.mspx?mfr=true However, I'd like to see a complete list, just like the "Group Policy Settings Reference" on windows.com/downloads, with a column that says which CSE is responsible for processing which setting. For example: if we use the DFS.admx to change the DFS network policy. Is there a DFS CSE that processes this policy, or is it processed by one of the default CSEs? Does it require an extension at all? Maybe the CSE list on the link above is quite complete, and all other settings are processed by the Group Policy Engine itself? Is there such list around somewhere? (that links every possible GP setting to the GP Engine or CSE component that processes this setting) Many thanks in advance, Hendrikus TERWINT Consultant Avanade France hendrikus.terwint@xxxxxxxxxxx<mailto:hendrikus.terwint@xxxxxxxxxxx> Prestataire pour le compte de SEDI-RSI, site de Bagnolet Tél. : 01 55 82 39 70
