In Windows, you can also right-click on your drive in 'This PC', select properties, and then go to the 'Disk Cleanup' menu, where the OS will show you a few files that can usually be safely be cleared up. Deleting system files can result in a computer that won't work anymore, requiring a Windows repair, or worse, re-installation.
