A 90-year-old relative just called me saying he had just upgraded to win10 (why, I don't know) but he's unable to log in because it asks for his password. He never had a password in win7. I haven't upgraded myself so don't know much about this. He's going to get his "better" hearing aid and call me back so I can talk him through this. Please for the love of all that is holy, can someone tell me what password this win10 upgrade wants.
