A new build of WWA has been uploaded to SourceForge. This one adds a new report to the main sidebar (filename: report7.asp). This report adapts the SQL code used by one of the SCCM Windows 7 Readiness web reports and adds a summary tabulation at the bottom. The target collection can be selected from a drop-down list at the top-right of the report page. Give it a try and let me know how it works for you.
