Software useful for a thorough maintenance computer (up to 3 machines), especially if it is older and begins to be very dirty. Some actions are automatic, others recommended (one can deny), others are triggered by the user according to his needs. Everything is well explained, but you still have to know it to avoid panic by validating (or not) actions. After the first "clean" and personal standby configuration software optimizes the system in the background. This software will give some oxygen to your old machine, but do not expect still recover its original youth. Nothing worth a total relocation of the System, but always hesitate to get there ... On a newer machine TuneUp Utilities allows regular maintenance quite useful, without going into the maze of hidden features of Windows. And if you like the fantasy a module even allows you to change the look of your entire system.
