[gptalk] Re: Can Group Policy Settings be accessed and set from an application

Thanks for the tip about you polviewer utility. I see how it works on XP. 
However, I'm not able to find and "pol" files in Vista. Does anyone know where 
they are located on Vista?

  Admin Templates in Vista, like OS' before it, are governed by template files. 
In Vista these are called ADMX files and are XML files that govern where a 
particular policy makes a setting in the registry. This was the same with ADMs 
in previous OS'. These files serve as the template for values that are written 
to the registry.pol files in the GPOs. This file is simply a Unicode-encoded 
text file that can be read to and written from (see my polviewer utility for a 
registry.pol reader). So, programmatically you could get into this file and 
write your setting provided you know the value in the registry that underlies 
it, which you can glean from the ADMX files in c:\windows\policydefinitions. 

  You might also look at the IGroupPolicy object interface. Others on the list 
have more experience with this interface than I do but it does provide some 
programmatic access into registry policy.

  In Vista, there is configuration parameter "Turn Off Program Compatibility 
Assistant" defined as a group policy under Computer 
Configuration->Administrative Templates->Windows Components->Application 
Compatibility. Do you think it's possible to access this configuration 
parameter through application code? I've looked up registry.pol on on MSDN but 
not seen anything that leads me directly to this parameter. If it's possible, 
Vista specific policy info probably not published on MSDN yet.

    Noting changes in particular in Vista. Note that policy areas such as Admin 
Templates, and Software Restriction policy store their settings in a published 
format (look up registry.pol in MSDN) so its not completely opaque, but I think 
that because each CSE has historically been owned by the respective product 
groups within MS, and no one dictated a standard set of interfaces, it would 
have been difficult for MS to publish this information. For example, Admin 
Template settings are driven by ADM/ADMX files but security settings, for 
example, are hard-coded into the GP editor DLL responsible for that extension 
(for the most part).

    So if I understand this correctly, it is possible to configure group 
policies through an appliction with Microsoft's gpedit.msc application, but 
Microsoft is just not sharing the methods with anyone so we're not forced to 
use their application. That's unbelievable, but not surprising. Up to now I 
think most users do not have a need to touch group policy settings. However, 
with Vista Microsoft is relying more heavily on group policy settings for Vista 
configuration settings.  

    Does anyone know a method for accessing group policies specific for Vista.

      Generally speaking, you can't do this. There is no API that will get you 
access to all GP settings. Part of the problem here is that each CSE that MS 
ships contains its own mechanism for writing and storing settings, with their 
own formats. So, there is no unified API that provides the single interface.

      Not a great answer, but one that I've been repeating since about 1999 :). 
Maybe one day it will get solved.

      Hello All,

      I have an application where I need to manage group policy settings from 
an application. I'm new to Group Policies in Windows, have been reading 
everything I can find but so far I've not definitive methods which enable group 
policy settings to be read and configured from a C++ application. Seems to me 
that if group policies can be configured with Windows group policy editor, it 
must be possible to implement my own application. 

      Appreciate any help anyone can provide to get me up to speed on this. 

      Thanks in advance,

      Dave
