Are you referring to the UUID property of the Win32_ComputerSystemProduct WMI call?

This query is for a collection in NS 6.  If you want a report you can use that as a starting point and select the fields you are looking for.

SELECT  
 rkc.ResourceGuid as [Guid],  
 COUNT(DISTINCT LEFT(rkc.KeyValue, charindex('.',rkc.KeyValue)-1)) AS [Count]  
FROM ResourceKeyChanged rkc 
JOIN vComputerResource vcr ON vcr.Guid = rkc.ResourceGuid            
JOIN Inv_AeX_AC_Identification aci ON aci.[_ResourceGuid] = vcr.Guid 
 AND (lower(aci.[System Type]) = 'win32' OR lower(aci.[System Type]) = 'win64') 
WHERE rkc.ChangeTime > getdate() - 7  
 AND rkc.KeyName = 'name.domain'  
 AND rkc.KeyValue LIKE '%.%' 
GROUP BY rkc.ResourceGuid   
HAVING COUNT(DISTINCT LEFT(rkc.KeyValue, charindex('.',rkc.KeyValue)-1)) > 2
