If you can not log in to PC, and don't have a linked Microsoft account the there is nothing we can do to help you because it is against forum rules to tell anyone how to hack around passwords or security measures and that is the only remedy to this issue.
I know you think it is crappy that we wont help you, but when someone steals your laptop at the coffee shop and they feed us some made up lie sob story and we still tell them no, you will be glad.
