Hi, I'm not an expert with computers. I'm running a windows 8 laptop that's almost 2 1/2 years old, I mainly listen to music and browse web/play games on off through out the day on it. I don't do any high end gaming on though I do play modern 3d games like FFXIV, Ultra Street Fighter IV and Counterstrike: GO. I've noticed it get a bit slower over the years and I know that's normal, but I'm sure something can be done software/file side to improve things. What tasks should I perform other than defrag and cleaning registry to increase performance? What can I do every week to maintain it better?
