Hello,
In Windows Vista, programs that don't need admin power, don't receive it,
regardless of whether you are an administrator.
This is accomplished by prompting you for permission whenever a program runs
that needs admin power, if you are an administrator. This allows you to know
for sure which programs are running with admin privielges, and which aren't.
This behavior of the administrator account is new in Windows Vista, but the
nature of the admin account has not changed - i.e., both administrative and
non-administrative programs run inside of your single admin account (There
is not technically a non-admin user and an admin-user).
If you are NOT an admin and you run a program that requires admin access, it
will ask for the username and password for an administrator in order to
continue, and that program will run as if it was started by that
administrator account (like run as, in Windows XP).
Admin accounts and user accounts are still different.
Windows Vista takes great pains to ensure that many applications that do not
work correctly as a standard user will work in Vista. Of course, this isn't
perfect, but the situation is a lot better than it was with Windows XP.
The "built-in" administrator account is disabled by default in Windows
Vista, and is only kept around for an emergency- you can only use it in safe
mode if you accidentally delete or get locked out of [via password policy]
all of the other admin accounts on your computer.
This makes the admin account with a blank password not much of a risk, since
you cannot use it except in that limited way.
Also, by default Windows Vista prevents you for remotely administering your
machine using the admin shares unless you are part of a domain and are using
a domain admin account. This does not affect remote desktop. You can change
this behavior by modifying a registry value.
