IIRC, even Administrators can't run as SYSTEM. To run as SYSTEM, you need to
somehow coerce a process that runs as SYSTEM to do something for you. Usually
achieved by running a [temporary] service and having it do what you want to be
done.

Notably, SYSTEM (but not Administrator) can impersonate any other user without
needing a password (other users can only impersonate with a password - i.e.
they need to authenticate themselves). In that sense SYSTEM is the true root
(though there are other high-privilege accounts, such as Trusted Installer and
Local Service that might be able to do the same things).
