Windows 10: c drive keeps filling itself up after trying many suggestions

We have tried removing files and moving files, unhiding files and using disk cleanup and everything we can find short of formatting the drive. The c drive has 465 GB and when we select "all files" it reads only 135GB used, however when we open properties on the c drive it says 463 used. We cleared off everything we could, ran a cleanup and it temporarily a few hours had some space, but a few hours later it had refilled itself. We think it might be a corrupt system file but we do not have enough room to download a new version of Windows because of this issue. Please help.

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.
