Why Low Free Space Slows a PC
Windows constantly creates temporary files and uses disk space for paging memory. When the system drive is nearly full, Windows has to work harder to find room for these operations which results in pauses and slow launches.
Large update packages, old installers, and cached media can accumulate without you noticing. Cleaning them frees gigabytes and reduces background maintenance tasks that scan and manage those files.
