One method of backing up the Win95 registry is to copy files \windows\system.dat and \windows\user.dat to other media. However, when 'user profiling' is active there is one user.dat file for each user in folder \windows\profiles\logon-ID (logon-ID is the ID used to logon with), as well as that in \windows. Am I right in thinking that during logon processing, \windows\profiles\logon-ID\user.dat is copied to \windows\user.dat and that the backup method mentioned above will still be valid *for that particular user*, thus leaving other profiled users 'user.dat' files unprotected?
