To add this feature in Windows 95/98, you can either edit the policies using Poledit, or use a third party program to control log ons. A client I have has been very happy using ScreenLock (they used to have a demo available, but I'm not sure if they still do... search for it in Google or on download.com). I'm sure there are many other third-party tools available as well. Just look around a bit, and I'm sure you can find something. By the way, why do you need to implement this? Generally, it's not that big of a deal not having passwords on a system, except in a corporate environment or on a computer which holds sensitive information.
