Seasoned CM admins should already understand the difference between SQL and WMI queries and how to write a subselect query. If you do, you should be able to skip ahead with just this one reminder-with CM's ability to use exclude or include in a collection query, you won't have to make subselect queries as often.
Now for all of the rest of you, we're going to show you how to make a query to show all machines which have Office installed. Then we'll show how to find all machines which don't have Office 2010 installed (and for that we need a subselect). We'll do this first in SQL and then again in WMI. SQL is for reports where WMI is more commonly used for CM console queries and collections.
You will need access to any machine with Microsoft SQL Server Management Studio (SSMS) installed. You will need SQL access to your primary site or CAS.
