Prompted with a "The user name or password is incorrect" message when you tried to log on Windows 7 HP/Sony/Dell/Acer/Lenovo PC? It's really frustrating if you need to login in to your Windows 7 urgently. Believe it or not, this is always a solution to fix a problem of "Incorrect Windows 7 password".
Here are several possible solutions to fix this problem:
Check if Caps Lock is off or not. Passwords in Windows are case-sensitive. For example, if your password is "AaBbCcDd" and you turned on Caps Lock, you typed "AABBCCDD". Windows regards it as wrong. You should make sure capitalize each letter in exactly the same way that you did when you first created it.
Sometimes, smart people will make a stupid mistake as well. So ensure the password you are typing is for this account if there is more than one user account on your computer.
If there are other people that have accounts on your computer and one of them have administrator privilege, you can ask him for help. (Suppose You are the only user on this computer, skip to Way 4 to use Windows Password Key to directly reset lost Windows 7 password.)
Since administrator can manage the passwords for all the users in Windows 7, this person can change your Windows 7 password for you from within his or her account.
If you've tried confirming Caps Lock and account, there are no other users on your computer, then it's time to try something new. It's Windows Password Key. It is software designed to recover, reset or delete your Windows 7 password. It covers all kinds of accounts on your Windows 7 computer: administrator account, user account and guest account. You can follow some simple directions below to get you back into Windows.
Note: Due to the difference in different computer manufacturers, you may need to press F1 or Del button to enter BIOS. Usually you will see the indication on the login screen.
I am sure that you can login into Windows 7 with the new password now. If you encounter wrong Windows 7 password again in the future time, try Windows Password Recovery Software to reset wrong Windows 7 password.
