Forgot password for my Windows 7 OS. It won't let me go sat the Windows 7 login screen.

Question

I reinstalled Windows 7. It asks for my password (At the login Windows 7 screen). But I don't remember the password. Is there a way to reset my password without knowing my password when Installing Windows 7.

Hi,
If the computer have another account which have administrator privilege, you can use the account to help resetting your password.
Click start>control panel>User Account and Family Safety>User Account>Manage another account>click the account that you want to change the password for>click Change the Password.
But if not, you can refer to the article below to enable the built-in administrator account and then do the steps above.
After that, you’d better to create a password reset disk to avoid a problem like this in the future.
If no administrator account, and you don’t have a password reset disk, you may need to reinstall windows.
