The instructions found on this blog saved me about 57 mouse clicks the other day. Maybe not 57 precisely, but a LOT OF CLICKING.
Basically you get into Windows WMIC and tell it to find all the software from the vendor “Autodesk” and remove it.
One tiny snag I hit was that it forced a reboot after one of the uninstalls. Just logged back in, ran the command again and voila! A ton of Autodesk software was gone!
Kudos and big thanks to the original author over at Prosoft.
