It would be ideal if the Publisher was able to show somewhere how much disk capacity is used in the WsusContent and/or UpdateServicesPackages directory for updates belonging to the Patch My PC category. I think UpdateServicesPackages would be most valuable to know.
It is very common for us to receive queries asking why these directories are using so much disk space. While our content is stored by WSUS in these folders, other third party publishers also end up with their content there, too. It would provide the customer a quick way to understand which third party publisher is using the most space.
