Who are authenticated users on my computer

[seraphio]

Hello, I was checking my C:\ permissions panel and saw that authenticated users had special privileges. being on a home network with room mates I do not want any of them to have access to my computer or files. I disabled sharing in windows 7, My question is:
How do I find out who are in this "authenticated users" group??

authenticated users are users who have successfully logged on to either specific machine or domain.

Ensuring you have disabled any sharing and have passwords on all accounts is broadly speaking enough to protect you from your room mates.

Note: this will not prevent them from shaving your eye brows off while you sleep.

Anyone that has an account on your PC and has authenticated against that account.
