I use CCleaner for maybe even 10 years, a great tool. But Windows 10 (a few older versions as well, but somewhat hidden) has something similar called "Disk Cleanup" (Win key > enter "Disk Cleanup" > "Clean up system files" > Check all marks). "Disk Cleanup" removes stuff that CCleaner doesn't, so I use them together. You can even remove system restore and shadow copies (Win key > enter "Disk Cleanup" > "Clean up system files" > "More Options" tab > "System Restore and Shadow Copies" > "Clean up" button).
