Right. And keep in mind that build number doesn't change for a given major release (i.e. all versions of XP are build 2600, all Vistas are build 6000, etc.) From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Nelson, Jamie R Contr 72 CS/SCBAF Sent: Thursday, July 26, 2007 1:58 PM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: WMI Question No there shouldn't be a problem with using a "generic" filter like that. Don't know about everyone else but I do that all the time. If you want to target a specific build or service pack just make a separate, more detailed filter that looks at the Build or Service Pack (CSDVersion) properties.

Instead of having my filters look for the exact string I use the "like" argument so it covers all versions and builds of XP or Vista. I guess the caveat would be if you wanted to apply ( or not apply) something to a specific build or service pack of an OS. Examples: WMI Filter looks for "Microsoft Windows XP" anywhere in the caption SELECT * from Win32_OperatingSystem WHERE Caption LIKE "Microsoft Windows XP%" WMI Filter looks "Vista" anywhere in the caption SELECT * from Win32_OperatingSystem WHERE Caption LIKE "%Vista%" Instead of looking for Vista's new caption "Microsoftr Windows VistaT Enterprise" For those looking for examples: http://grouppolicy.editme.com/WMIFilters Mark Mills
