If your using win98 and MS explorer, go to the control panel then select network and then scroll thru the log on options, and lookk for 'microsft FAMILY logon or something similiar. This will activate password save but you will have to log on each time yopu boot your computer unless your auto log on via TWEAK UI INF You can get the very excellent tweakuiinf file from your win98 CD via doing a file search for 'tweakui.inf'and then right click on 'install' and then reboot, go to you control panel then select Tweak ui and then you can takeover your desktop control to customise your setup and log on.
Have fun
