Thorbjorn wrote on this subject once before on this list. Essentially, there
is no built-in way to form a WQL statement to look for a particular registry
value. WMI uses the StdRegProv provider to talk to the registry and it does
not expose an information model that allows for simple select queries.
However, I believe Thorbjorn's approach involved writing and compiling your
own MOF file on each target system to expose this. Not trivial. 


I think your better bet is to simply do that reg. value query within the
startup script. That information is much more accessible using standard
vbscript methods than trying to make a WMI filter do this.

Subject: [gptalk] WMI filter on registry keys


Does any know how to use a WMI filter for a GPO that will return true if a
registry value (not key) contains expected data.  We are essentially trying
to make startup scripts run once to resolve major issues.  In that, once the
script completed it's work, it writes to the registry, then the WMI filter
would prevent subsequent attempts to apply the GPO (Denied WMI filter) if
the registry entry contained the defined value.

Apparently direct access to the registry is not available in a class.  But
the registry is exposed as a method in Root\CimV2
