Defragment your HDD Harddisk

A SSD you don’t have to deframent. At the end of the cleaning proces defragment the HHD hard disk so that it can read and write faster. Choose a disk defragment program and let it do its work. This may also be repeated. After this last operation, your PC is clean and safe again and if got faster it was definitely worth it. If not, then there is probably not much speed to gain, but your PC is now completely up-to-date.
