Windows 10 Clean Up with the bulit-in Cleaner (No download and install) - Windows Disk Cleanup
We can cleanup Windows 10 in a very simple way by using built-in cleaner which is Disk Cleanup. We can simply type in 'Disk Cleanup' at the Start menu. Then you will open this. Now we can see the cleanup list and you can select what you want to clean. However, in this menu, we cannot clean up system files, so let's hit 'Clean up system files' button. Then we can see the below. Now we can see more comprehensive list of cleanup. Let's select what you want to clean and then hit the OK button. We will see the above image and will be finished!
