Windows 10: Password forgotten - stuck on login screen

I got my brothers old laptop with Windows 10, and i removed the picture password which was the only way me or my brother could get into the computer. Me and my brother can't remember the password or the pin. I am stuck on the login page, with no way possible to get back into the computer.

Forgotten login password

My son has loaned his laptop to me. But he has forgotten his login password! Therefore I cannot change user on login screen.

 

Forgotten Password!!

Thanks, Brink!

Was successful in changing the password on the person's local account. But leaving the 2 accounts showing on the login screen will be very confusing for the 82 yr old person owning the laptop..

As suggested, I signed in to the built-in Administrator account, and now both accounts are local account and Administrator?? Did I do something wrong?

Is this way to stop the built-in Administrator account from showing on the login screen:

1. Hold the Windows Key while pressing “R” to bring up the Windows Run dialog box.
2. Type: net user administrator /active:no
3. Press “Enter“.

 

Forgotten Password

If you use a Microsoft Account of any form to login to the computer, you can use the Microsoft
Account Password Reset page to prove your identity and reset your password. You’ll need access to a phone number or alternate email address already known on your account to verify your ownership.

• This won’t help if your computer is not already logged-in. You can change the password on the website all you want, but the computer won’t “know” the new password yet, so you’ll need to use your older password to login. If you don’t know that and are still
  stuck, read on to see how to force reset the password.

If that fails, any administrator-level user can reset other user’s passwords on the computer. If you have another admin-level user on the computer, login to the account, then go to the Control Panel to reset
the forgotten account’s password using
these instructions here.
