C Drive Keeps Filling Up

Thanks. Extremely interesting article. I followed the steps as outlined, but when I was as the step to Stop the Windows Modules Installer Service, it was already stopped. So I was not quite sure how to proceed, so I abandoned the process. Since I had
already manually deleted most of the cab files, I now have 190 GB free space. I will closely monitor the free space to see how quickly it fills up, and if it fills up as quickly as the article suggests might happen, I will try again to follow the instructions
to see if I can get it to work. With the service already stopped, and set to Manual, if I get to that point again, do you have any suggestions on how to proceed? Thanks again for this very insightful article -- it sure explains a lot.
