Oops! I changed my User Profile in Passwords (Control Panel) to “all users use the same preferences”. Now I can’t access background, passwords, TweakUI, can’t see “C” in My Computer, can’t do anything. I tried Sys Restore, reinstalling WinME, restoring a full system backup–no soap. Removed the CMOS battery for a minute or so. Jumper-cleared the CMOS and reset the BIOS, but system still thinks there’s an Administrator for me to check with and won’t let me in anywhere. Any help on this? Thanks so much.
