So I downloaded Eraser to delete loads of unnecessary information that Windows tends to collect, and make it as if each time I switched on the computer it would be like as if I'm the first person to use it ever. But not only do I not know where to start, I'm afraid I'm going to - for example - delete something that will prevent my computer from ever starting up again or permanently damage it in some way! I would be very grateful if someone could explain the steps for me to take or point me in the right direction(s)!
Big thanks in advance.
