    There are a number of ways to do what you're talking about, but I don't
    think that's necessarily the correct approach to solving what you're worried
    about. There are two kinds of permissions on a microsoft system (assuming
    that you're running NTFS which XP normally does) share permissions and
    Access Control Lists. You should check your drive and make sure that any of
    your shares (folders with the little hand under them) are not set to
    everyone (the default), I usually use authenticated users or something like
    that but if you're really paranoid you could add each of your four accounts
    by name. ACLs on the other hand aren't really for protecting you from
    outsiders, they're more about protecting you from authorized users. For
    example you may not wish to give everyone who uses your machine access to
    your mp3 files, in case they might accidentally delete one.
        As you have an always on internet connection, the main three things you
    should do as a home user to protect your system are: 1) Install a firewall
    (zonealarm is free, there are lots of others that would work just fine as
    well) 2) Install and keep updated an anti-virus program. My personal
    favorite is norton corporate, its packed with features, but if you're on a
    limited budget you can get AVG for free. 3) Download and install all
    microsoft updates.
        There are lots of other things you can do to secure your computer, but
    just by doing these three you'll eliminate 95% of all trouble you'll
    probably experience as a home user.
