The LocalService account is a predefined local account used by the service control manager. It has minimum privileges on the local computer and presents anonymous credentials on the network.

This account can be specified in a call to the CreateService and ChangeServiceConfig functions. Note that this account does not have a password, so any password information that you provide in this call is ignored. While the security subsystem localizes this account name, the SCM does not support localized names. Therefore, you will receive a localized name for this account from the LookupAccountSid function, but the name of the account must be NT AUTHORITY\LocalService when you call CreateService or ChangeServiceConfig , regardless of the locale, or unexpected results can occur.

The user SID is created from the SECURITY_LOCAL_SERVICE_RID value.

The LocalService account has its own subkey under the HKEY_USERS registry key. Therefore, the HKEY_CURRENT_USER registry key is associated with the LocalService account.

The LocalService account has the following privileges:

  • SE_ASSIGNPRIMARYTOKEN_NAME (disabled)
  • SE_AUDIT_NAME (disabled)
  • SE_CHANGE_NOTIFY_NAME (enabled)
  • SE_CREATE_GLOBAL_NAME (enabled)
  • SE_IMPERSONATE_NAME (enabled)
  • SE_INCREASE_QUOTA_NAME (disabled)
  • SE_SHUTDOWN_NAME (disabled)
  • SE_UNDOCK_NAME (disabled)
  • Any privileges assigned to users and authenticated users
