“Windows has a built-in Disk Cleanup tool, and it works very well. Microsoft has been improving it, and it works even better in the latest versions of Windows 10. This tool removes temporary files, previous Windows installations, log files, old Windows updates, thumbnails, and various other cache files. If you’ve never run it, you can probably free up a few gigabytes of space by doing so. We don’t recommend a CCleaner alternative because Windows can already do a great job at freeing up space.”
