If you have forgotten your Windows login information, the easiest way to access your account is by logging into an administrator account. This administrator account has enough control to fully manage your account, and remove the password. The other option is to use a password reset disk, but this method is available only if you've created the disk beforehand.
Ok, whether you have an administrative account or a password reset disk, you can follow the below steps to easily reset forgotten Windows password.
