Periodically Check Your Network Profile List and Settings
Since any network you connect to can be added to your network profiles or preferred list, either by you or automatically by Windows, you should periodically check for other networks and remove them from the list. This is because Windows might try to automatically connect up with that other network sometime. As discussed in the previous tip, this compromises any shared files on the computer. You also want to make sure you don’t have the network settings on any Windows XP computers set to automatically connect to any available network.
