Determine which type of account you have, then reset the password.

Microsoft account
Microsoft Account is set up using an email address, you can reset your password online. Use any device connected to the Internet to open the Microsoft password reset page from below link:

local user account
Reset your local user account password using a password reset disk, but to use this option, you must have previously created a password reset disk (or USB drive).

last option, Install new Windows.
