"Authenticated Users" vs. "Users"

Question

I'm setting up a profiles structure on a server starting with the master folder that'll house all the profile subfolders.  the default permissions on a newly created folder always has the admins and creator/owner and system accounts, but by default
it also has Users.  Yet in some pre-existing installations I've come across I've seen Authenticated Users put there instead, so the admin must have had a reason. 
So the question is, what's the difference?  Since any domain user would have to authenticate to get into any resourcse anyway, is this not just the same thing?  What would be a scenario whereby you should use one over the other? 
Thanks! 

Answer 1

Authenticated user group is builtin user group & any user created in domain default became member of this group, where as you can't see or manually modify authenticated user group to add or remove members. Authenticated user group can't be added into
user created groups like Global/Domain local/Universal group but it can be added to built in domain local group in AD. Even it contains member of trusted forest. Authenticated user group membership is controller by OS.
Domain user group is a global group & it too contains all the users from domain where as its member can be managed like manually can be added or removed by administrators. Domain user group is visible in ADUC console.
