To fix this, you can do it from the working account.
In short, I am not to familiar with computers but my son is. We both have passwords to get into our own session (?) in XP (when you first turn the computer on). My son figured out my password so he could change the parental blocks and has also changed my password. He claims he can't remember what he changed my password to (yeah right). Is there I way I can figure out the password or override it, or do I have to uninstall something and lose all of my saved files and pictures.
