This is a second computer for me that my nephew set up for me. I hardly used it after he set it up for me and now that I have Wi Fi, I'm using it again, but neither of us remembers the password he set up for me, and I have to continually sign in as a guest and then re-sign into email, etc, as nothing is saved. I need to know how to reset my password. When I try to reset it, it asks for my original password, which, again, I don't remember!
