Customer has small permission-based XP workgroup consisting of 4 PCs, NASs & NAPs. They have upgraded to Windows 7 & want as much security as reasonable/possible. In XP, we disabled switch user option, enabled ctrl+alt+del logon sequence, lockout policies, enforced complex passwords, etc. We have figured out how to do this in Windows 7 w/o being connected to a domain but want experts to advise how to setup the network since Windows 7 has created different networking arrangements. In addition, I have *not* located how to remove the auto username population (e.g. I need the username/password to be manually filled in by the user as I did in XP). I am pretty sure out of the 3 Windows 7 sharing options (Public folder sharing, individual folder sharing, and homegroups) the most secure would be individual folder sharing. How do you recommend using Encrypting File System (EFS)?. Lastly, I cannot find out where to turn off simple file sharing, if that is even an option, & if it’s recommended. In XP it obviously was.
