How to collect installed (non-Microsoft) software updates?

Hi all,

I'm trying to find a way to collect all the non-Microsoft updates that are installed on my clients (e.g. various Autodesk AutoCAD servicepacks installed) but everywhere I look I only find informations about Software Updates Management which is another matter.

Do I have to modify hardware inventory to collect the registry keys that I need or there's something I'm missing to collect third-part software updates/servicepacks?

I simply need to collect the list that you get in "Programs and Feature" under "View installed updates" in Windows 7.

Thanks

Davide
