That will sort of work but the issue is the collection has ALL our software updates applied to it. I want these clients to pickup the rest of the updates but there is one single update we are pushing out that I need to exclude these clients from getting.
Also how would SCCM cope with the conflict as the software update collection has a query to detect all our client machines, if I create a manual collection and add them to it they will then be in the include and exclude rule.
