how do i prevent passwords from being saved on all user accounts
Forgot your Windows admin password? Don't worry! I had the same problem as you. when i try to boot up in safe mode, but opened in the same window as before, still asking for my password. This situation can only use the third party software. I solved that with Windows Password Reset 9.0. http://www.reset-windows-password.com/reset-windows-7-password.html
