System Mechanic essential software review
 

For us this is a vital item of software we use all the time to keep our computers running as efficiently as possible especially if you are using Windows XP software. We use System Mechanic once a week as we are using our computers all the time but you will only need to do it once a month probably. It all depends on what you do with your computer and how much you use it.
