You could usually keep getting a message telling you that the user name or password is incorrect when you tried to log in windows. Here are some tips for fixing this forgotten or lost Windows password problem:
1. Windows password is case-sensitive, which means that every time you type the password, you have to type each letter exactly in the same way when you first create it. If you press CAPS LOCK accidentally, then you are typing your password in all capital letters inadvertently, then you must remember password have been make in capital letters when you log on next time. So, please make sure CAPS LOCK is on or off, and then type your password again in order to recover Windows password.
2. If you forgot Windows password, you need to reset your password, either with a windows password recovery tool or an administrator account. For more information, see How to Recover Windows Password with CD/DVD or How to reset windows password with USB Flash.
3. If your computer is on a network, a network administrator has the ability to reset Windows password. If you think this might be the problem, check it with your network administrator. If your computer is in a work group, anyone who has an administrator account on the computer can change Windows password.
4. If you have more than one user account on the computer, you might be trying to log on the wrong user account. So, make sure you are logging on by the account that matches the password you are using.
