For years now, my login page (when booting up) shows my password, with a bold border around it, at the top of the screen. To enter the PW would require only copying that, although it isn't obvious what it is. Nobody else ordinarily has access to this computer. Someone said it might be a BIOS (if that's what it's called in Vista) issue.
(1) what happened to create it,
(2) what might be a problem I haven't thought of, and
(3) what would happen if I fooled around with it -- changed the actual PW, for instance -- but wouldn't welcome any problem that could result.
Any suggestions? Is there any reason to "fix" it?
