The best way to describe and set apart the LocalService account is to say that it is a pre-defined local account, used by the service control manager. One NOT recognized by the security subsystem, with minimum privileges on the local computer, presenting anonymous credentials on the network.
Also referred to or named the NT AUTHORITY\LOCALSERVICE, having NO password.
The user SID is created from the SECURITY_LOCAL_SERVICE_RID value
Sports its own subkey under the HKEY_USERS registry key (associated with the LocalService account)
The LocalService account has the following rights, access and privileges:
Any privileges assigned to users and authenticated users
So to summarize, it is a non-privileged user on a local computer, presenting anonymous credentials to remote servers. Used best to minimize security risks. It is a service user account that runs with very limited privileges (see also LocalSystem for ‘opposite’).
