Windows 10: How do I use command prompt to erase information and change logins?

I found an HP laptop somebody had thrown away in the trash. The laptop actually works but upon starting the computer up, it has a user account and password on the device that obviously I do not know. It does not give me the option to use an administrator account or guest. I know that I can access the bios and use command prompt to access something inside the computer allowing me to either alter the password or to remove the account and password or something of the sort allowing me to log into the device so that I am able to factory reset the device. Please help. Why do I need to type into comm

:)

 

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

You can also change password by clicking on Sign-in options in the left pane and choose change password in the right pane.
