The User Profiles command lets you create groups and users, so that you can share settings and lens information. For more information see, Using the profile manager with multiple users.
About Windows and User Profiles: Don't confuse the NeurolucidaProfile manager with a Windows login or account management function. The information you use to log on to Windows, use for your Internet account, and email are not necessarily the same as the group or profile information you use with User Profiles.
