There are many reasons to prevent Windows from remembering passwords – these include..
A shared or public computer, Giving a computer to a friend or family member or selling a computer, in this case we would really recommend wiping the whole thing and reinstalling from scratch.

The types of password that Windows remembers generally falls into two categories.
Internet browser based
Separate applications such as messenger clients Yahoo, MSN etc

Internet Explorer – Tools menu – General tab. Delete – Then you have the option to delete any saved passwords.
Firefox – Tools – Options – Security tab – Saved Passwords under the password section.
