My thoughtless cousin created a new account on my Grandmothers PC and now her account its the only one that appears at login. But shes not talking to the family so my grandmother is at a crossroads with the PC either find out the password and delete the account or reset the PC. But i found that one of the login options is a use of a 4 digit pin. Is this something that is made when creating a MS account to sign in? Or could i be trying to guess this 4 digit pin for nothing.
