I would like one that starts at boot and diaables the keyboard
No computer is ever really pasword protectable..
There is the Cmos eraser one that was mentioned..
For Win95 to win 98 (and me) there is a way to delete, or disable teh
password, and even for Win XP there is programs that youy can get that
totaly removed passwords....
there are some clever registry hacks, and ways to make the computer more
secure (like disabling the cancel button in windows logon so password is
mandatory, AND disable checking floppy drive first for bootup AND password
protect the setup for the bios, and disable the function startup keys.. that
is about the safest you'll be able to get that i know of.. however, clever
people can still get around it (linux may be a little harder to crack
though).
Good Luck
