Windows – Disabling Password Complexity Requirements on Windows 7

You can set it through Local Security Policy in Windows 7. To enable Local Security Policy see this one

Once you Enable the local security policy

1.Type Local Security policy in search Box(other way can be achieved through control panel) 2.Expand Account Policies → Password Policy. In the Right pane, select and click Password must meet complexity requirements.

Notable things while you set Password Complexity :

• Not contain the user’s account name or parts of the user’s full name that exceed two consecutive characters
• Be at least six characters in length
• Contain characters from three of the following four categories:
  • English uppercase characters (A through Z)
  • English lowercase characters (a through z)
  • Base 10 digits (0 through 9)
  • Non-alphabetic characters (for example, !, $, #, %)
  • Complexity requirements are enforced when passwords are changed or created.

I've just taken a look at the Password Policy on my computer (Win 7 Ult 64-bit) and even though I am never prompted to change my password, the value of Maximum password age is set to 42 (default). I know that when it is set to 0, a user's password will never expire, so you should be having no problems setting a password.

I've also tried with the value set to 0 and I haven't been able to replicate your problem. You could try changing the value to something other than 0 and then changing it back to 0 and see if that helps. Or you could change the value to an x number of days and tick the Password never expires option when you create a user to bypass that setting.

Finally, you could try setting a password that meets the complexity requirements as the Group Policy Object may not be applying the settings properly.
