i have a Windows 7 Professional and i logged in administrator account. i want to change the password so i go to the control panel>user accounts and family safety>user accounts>create password for your account. after i complete typing the New password and confirm new password i click the create password button. and a window appears that the window cannot change the password. what would be the problem??

If you are logging in as Administrator (the account whose password you want to change), then try typing CTRL+ALT+Del and then choose "Change a password". Also, right-click Computer and click Manage. Select "Local Users and Groups" and then select Users. Click the properties of the Administrator account and make sure "User cannot change password" is unchecked.
