Windows 10: C drive space filling

My C drive space in Windows 10 is filling up rapidly. I tried deleting CBS files but that weren't occupying much space.

I used Treesize but not able to make sense of which file is occupying unnecessary space and which file to delete.

Unallocated Space to C Drive

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.

 

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.
