IN MY HP PAVILION  LAPTOP  IN THE REGISTY UNDER HKEY USERS THERE IS A LIST  BY NAME AS FOLLOWS:
                                                                                                                                                                        S-1-5-18

                                                                                                                                                                        S-1-5-19

                                                                                                                                                                        S-1-5-20

                                                                                                                                                                        S-1-5-21

Hi,

SID means a security identifier. It is a part of the Operating System

https://support.microsoft.com/en-us/help/243330/well-known-security-identifiers-in-windows-operating...

SID: S-1-5-21-3580036505-2828148361-1391708163-1001
* A subkey named for the Security Identifier (SID) of the current local user. This subkey contains the current user's profile. The data in HKEY_USERS\SID also appears in HKEY_CURRENT_USER.

Caution: You might crash the OS if you accidentally delete an important file
