One of the problems with the canned compliance reports is the lack of easily isolated Service Pack information, so I created a report that allows you to select Windows 2000, XP, or Vista and then filter out the most recent SP for that OS.
Here's some SQL that'll query computers with MS Office 2003 without the Office 2007 compatibility pack. Just go to reports, create a new one, and select 'Enter SQL Directly', then copy and paste the sql into there.
