This is my Sister laptop, caps key stuck, we finally got that to unstick, now she can't logon to her Windows 10...She has HP laptop...We tried running system repair, but she still couldn't add anything in the box...She made sure number lock wasn't on, so that is not the problem.. We also did a restore to previous time, it succeeded, but still could not add her Pin number... What else could keep her from adding her Pin in order too logon to her laptop?? Thanks for any and all help..

Thanks, patti686
