SCCM WQL Query – Clients without latest version installed

If you want to create a collection in Configuration Manager to show you all the devices that are not up to a specified version, then you can use the WQL query below:

 select SMS_R_SYSTEM.ResourceID,  
 SMS_R_SYSTEM.ResourceType,  
 SMS_R_SYSTEM.Name,  
 SMS_R_SYSTEM.SMSUniqueIdentifier,  
 SMS_R_SYSTEM.ResourceDomainORWorkgroup,  
 SMS_R_SYSTEM.Client   
 from  
 SMS_R_System  
 where SMS_R_System.ClientVersion != "5.00.8412.1007"  

Where “5.00.8412.1007” is the latest version number that you are currently using.
