A "duplicated clone"? No. It means that whatever operating system you are
using should have at least one user account with administrative privileges
that isn't used on a daily basis so you can get out of a pickle with it if
you need to.
In Unix and Linux, this is root. We almost *never* log into root's actual
account when working in those operating systems. I can't remember the last
time I logged into root in Linux. It just isn't necessary.
In XP, this means we don't use the built-in Administrator account for daily
work. In XP Home, you can't do this anyway since the built-in Administrator
is hidden by design. The only way you can access Administrator in XP Home
is to boot into Safe Mode. And that's A Good Thing because it means the
user can't mess it up and it will be there when you need it to fix the
system.
In XP Pro, this means that you don't use the built-in Administrator for your
own account. From a security standpoint, it is better to run as a Limited
user in XP but from a practical standpoint (because of older software that
won't work unless it has write-access to directories and registry keys that
are off-limits to non-administrative users) most people's daily user
accounts have administrative privileges in XP. Normally when you install XP
Pro, at the end of the installation routine you're asked to provide a
password for Administrator (this is the built-in Administrator). After you
do that, you're asked to provide the names of other user accounts you want
on the system (you don't assign the passwords then). If you don't create
other user accounts, you'll be logged into the built-in Administrator. If
you do (properly) create other user accounts, the built-in Administrator
will not have an icon on the Welcome Screen (to "hide" it). Unlike XP Home,
it will still be accessible from Regular Mode, however.
In Vista and Win7, the built-in Administrator account is disabled by default
for security purposes. Other operating systems such as OS X and some Linux
distros also do this. This makes having an extra user account with
administrative privileges extremely useful because, unlike XP, it is
completely practical and desirable to run as a Standard user (equivalent of
Limited user in XP) in Vista and Win7.
I hope this has exhausted your questions about user accounts. However, if it
hasn't then please let me know.
