Not that long ago I went to the house of one of my daughter’s friends. They needed to share in Internet connection and had also stuffed up the installation of some anti-virus software. Having fixed those two problems I also decided to take a look and see if the system needed any basic maintenance. To my shock I found that the hard drive was over 60% fragmented. I can only assume that disk defragment was never performed on the PC. The family couldn’t believe the speed boost they got!
