After windows 10 has perform an update I can't login to windows. (The computer is not mine, it is my friend computer)
I have used a PIN code to login to windows, and after the update it no longer accept the PIN code.
I don't know the email address nor the password.
I already tried to restart with command prompt, to enabled administrator.
Nothing worked, i always asked to provide a password that i don't have.
I don't want to erase and reinstall again.
Any suggestions?
