The following table describes changes in SID implementation in the Windows operating systems that are designated in the list. Capabilities represent an unforgeable token of authority that grants access to resources Examples: documents, camera, locations etc Any Capability SID added to Windows by first or third-party applications will be added to this location.

All values up to, but not including, the last value in the series collectively identify a domain in an enterprise. This part of the series is called the domain identifier. The last value in the series, which is called the relative identifier RID , identifies a particular account or group relative to a domain. A security identifier to be replaced by the security identifier of the user who created a new object.
A security identifier to be replaced by the primary-group SID of the user who created a new object. A group that represents the current owner of the object. A group that includes all service processes configured on the system. Membership is controlled by the operating system. A group that includes all users who are logged on to the system by means of a dial-up connection.
You can use this SID when restricting network logon to local accounts instead of "administrator" or equivalent. This SID can be effective in blocking network logon for local users and groups by account type regardless of what they are actually named. A group that includes all users who are logged on by means of a network connection.
Access tokens for interactive users do not contain the Network SID. A group that includes all users who have logged on by means of a batch queue facility, such as task scheduler jobs. A group that includes all users who log on interactively. A user can start an interactive logon session by logging on directly at the keyboard, by opening a Remote Desktop Services connection from a remote computer, or by using a remote shell such as Telnet.
In each case, the user's access token contains the Interactive SID. A user who has connected to the computer without supplying a user name and password.
Strictly speaking, such access is not anonymous because the security principal is known even though unidentified people are using the account.
When you grant permissions to Self, you grant them to the security principal that is represented by the object. During an access check, the operating system replaces the SID for Self with the SID for the security principal that is represented by the object. A group that includes all users and computers with identities that have been authenticated.
Authenticated Users does not include Guest even if the Guest account has a password. This group includes authenticated security principals from any trusted domain, not only the current domain.
An identity that is used by a process that is running in a restricted security context. In Windows and Windows Server operating systems, a software restriction policy can assign one of three security levels to code: unrestricted, restricted, or disallowed. When code runs at the restricted security level, the Restricted SID is added to the user's access token.
A group that includes all users who log on to the computer by using a remote desktop connection. This group is a subset of the Interactive group. A group that includes all users from the same organization. Only included with Active Directory accounts and only added by a domain controller. An identity that is used locally by the operating system and by services that are configured to sign in as LocalSystem.
System is a hidden member of Administrators. That is, any process running as System has the SID for the built-in Administrators group in its access token. When a process that is running locally as System accesses network resources, it does so by using the computer's domain identity. Its access token on the remote computer includes the SID for the local computer's domain account plus SIDs for security groups that the computer is a member of, such as Domain Computers and Authenticated Users.
An identity that is used by services that are local to the computer, have no need for extensive local access, and do not need authenticated network access. Services that run as LocalService access local resources as ordinary users, and they access network resources as anonymous users.
As a result, a service that runs as LocalService has significantly less authority than a service that runs as LocalSystem locally and on the network. An identity that is used by services that have no need for extensive local access but do need authenticated network access.
Services running as NetworkService access local resources as ordinary users and access network resources by using the computer's identity. As a result, a service that runs as NetworkService has the same network access as a service that runs as LocalSystem, but it has significantly reduced local access.
A user account for the system administrator. Every computer has a local Administrator account and every domain has a domain Administrator account. The Administrator account is the first account created during operating system installation. The account cannot be deleted, disabled, or locked out, but it can be renamed. By default, the Administrator account is a member of the Administrators group, and it cannot be removed from that group.
A user account for people who do not have individual accounts. Every computer has a local Guest account, and every domain has a domain Guest account. By default, Guest is a member of the Everyone and the Guests groups. Unlike Anonymous Logon, Guest is a real account, and it can be used to log on interactively.
The Guest account does not require a password, but it can have one. The account exists only on domain controllers. A global group with members that are authorized to administer the domain. By default, the Domain Admins group is a member of the Administrators group on all computers that have joined the domain, including domain controllers.
Domain Admins is the default owner of any object that is created in the domain's Active Directory by any member of the group. If members of the group create other objects, such as files, the default owner is the Administrators group.
A global group that includes all users in a domain. When you create a new User object in Active Directory, the user is automatically added to this group.
A global group that includes all computers that have joined the domain, excluding domain controllers. A global group that includes all domain controllers in the domain.
New domain controllers are added to this group automatically. A global group that includes all computers that host an enterprise certification authority. Cert Publishers are authorized to publish certificates for User objects in Active Directory.
A group that exists only in the forest root domain. It is a universal group if the domain is in native mode, and it is a global group if the domain is in mixed mode. The Schema Admins group is authorized to make schema changes in Active Directory. By default, the only member of the group is the Administrator account for the forest root domain.
The Enterprise Admins group is authorized to make changes to the forest infrastructure, such as adding child domains, configuring sites, authorizing DHCP servers, and installing enterprise certification authorities. By default, the only member of Enterprise Admins is the Administrator account for the forest root domain. The group is a default member of every Domain Admins group in the forest. By default, the only member of the group is Administrator.
Objects that are created by members of Group Policy Creator Owners are owned by the individual user who creates them. Objects that are created by members of these groups are owned by the group rather than by the individual. A local domain group. By default, this group has no members.
Computers that are running the Routing and Remote Access service are added to the group automatically. A built-in group. After the initial installation of the operating system, the only member of the group is the Administrator account. When a computer joins a domain, the Domain Admins group is added to the Administrators group.
When a server becomes a domain controller, the Enterprise Admins group also is added to the Administrators group. After the initial installation of the operating system, the only member is the Authenticated Users group. By default, the only member is the Guest account. The Guests group allows occasional or one-time users to log on with limited privileges to a computer's built-in Guest account. By default, the group has no members.
Power users can create local users and groups; modify and delete accounts that they have created; and remove users from the Power Users, Users, and Guests groups. Power users also can install programs; create, manage, and delete local printers; and create and delete file shares. A built-in group that exists only on domain controllers. By default, Account Operators have permission to create, modify, and delete accounts for users, groups, and computers in all containers and organizational units of Active Directory except the Builtin container and the Domain Controllers OU.
Account Operators do not have permission to modify the Administrators and Domain Admins groups, nor do they have permission to modify the accounts for members of those groups. Description: A built-in group that exists only on domain controllers. Server Operators can log on to a server interactively; create and delete network shares; start and stop services; back up and restore files; format the hard disk of the computer; and shut down the computer.
By default, the only member is the Domain Users group. Print Operators can manage printers and document queues. Backup Operators can back up and restore all files on a computer, regardless of the permissions that protect those files. Backup Operators also can log on to the computer and shut it down. A built-in group that is used by the File Replication service on domain controllers.
Do not add users to this group. An alias added by Windows A backward compatibility group that allows read access on all users and groups in the domain. An alias. Members in this group can have some administrative privileges to manage configuration of networking features. Members of this group have remote access to schedule logging of performance counters on this computer. Members of this group have access to the computed tokenGroupsGlobalAndUniversal attribute on User objects.
A group for Terminal Server License Servers. When Windows Server Service Pack 1 is installed, a new local group is created. A group for COM to provide computer-wide access controls that govern access to all call, activation, or launch requests on the computer. A built-in local group. Members of this group are allowed to connect to Certification Authorities in the enterprise. Servers in this group enable users of RemoteApp programs and personal virtual desktops access to these resources.
In Internet-facing deployments, these servers are typically deployed in an edge network.
