The C drive of the Windows system is updated by a few gigabytes every month.
After Windows updates every month, several GB of space are always lost from the C drive. It is necessary to find the specific location of the update residual files and delete them completely.
It's common for Windows updates to temporarily use additional disk space during installation, and sometimes old update files are retained, taking up several gigabytes. Windows has a built-in tool called Disk Cleanup that can help you safely delete these residual files, including old updates, without harming your system.
