faster pc : One of the easiest ways to make your PC run faster is to defragment your files. What does that mean? Well, Windows XP is notorious for storing segments of files in various locations, every time you create, modify or delete a file, it is further fragmented, and Windows has to spend more time trying to collate the pieces together before it can open, edit or delete it. Windows Vista has partially solved this problem, as it defragments in the background and thus your PC doesn’t slow down. Raxco has launched PerfectDisk to solve your defragmentation problems.
