Easyfix Tools work just like a computer boffin... they scan through your computers registry and pick out all the corrupted files.
Because your Windows registry is basically like a central nervous system for your computer, if it has any blockages or corruptions, your whole system is going to slow down. Errors start to appear and you generally have a growing problem on your hands.
However, as bad this might sound, the fact is that the Windows registry is the same on ALL Windows PC's. This means that a central piece of software can be used to fix the most common & damaging problems in it.
