hotmail

[Unregistered]

Can someone please explain hotmail accounts to me. I went to MSN the other day to sign in my hotmail account, and there was an account in the sign in thechop*0*@hotmail.com. I did not recognize this account therefore did not know what the password was. Everyone in our family says they did not enter this hotmail account. Someone told me to check the computer control panel, and look at user accounts, and then manage my passwords this account was visible here although no one remembers it. So we can't access our mail because no one remembers the password, or the answer to the secret question. How can I find out if this account was actually entered from my computer. Hotmail has been no help. Why would this hotmail account name be in my sign in box if we don;t recognize it. Help.
Thanks
