in Windows 2000, you can copy a user's profile if you have Administrator priviledges and go under Control Panel|System|User Profiles. one of the buttons copies from one user to another. this only copies the settings for the user interface preferences, not application preferences. these won't be copied, although i have heard of tools that will do that. however, the settings sometimes have hard coded user names and path names specific to the login, so you may have to edit the registry to fix things.

for automatic login, Windows 2000 allows you to set the default user under Control Panel|Users and Passwords. you can uncheck the box that requires a password to access the computer. Windows 2000 then asks which user you want to make the default.

i run Windows XP Home and not Pro, so i don't know if the settings are the same under Windows XP, but they should be in the general area.
