If there is a mix of Windows types and versions in the intranet, they all can be within the same organizational unit (OU). The problem could be: how to make a GPO be effective only for computers running a definite version/type of the operating system?
The answer is "WMI filtering". To add a filtering rule, open Group Policy Management Console, right-click on the WMI Filters node, select New, and add the following WMI query string:
Select * from Win32_OperatingSystem where Caption like "%string%"
where '%string%' is, for example, '%Vista%' if you choose to have a GPO working only for Windows Vista.
After the WMI filter has been added, you can use the WMI Filtering control at the bottom of the Scope tab when any GPO is selected to apply the filter to that GPO.
