Server Operators
ABOUT
Server Operators group allows members to administer Windows servers without needing assignment of Domain Admin privileges. It is a very highly privileged group that can log in locally to servers, including Domain Controllers.
Membership of this group confers the powerful SeBackupPrivilege
and SeRestorePrivilege
privileges and the ability to control local services.
As example we would use AppReadiness service because it has high privileges and starts as SYSTEM. But method could be used against other services too.
