The string of numbers might be the SID for an account on the computer.


There are usually at least a couple account references on the computer - some are created (and controlled) by the system and others are those accounts added by the owner / administrator.



Open the Command Prompt:

Windows key + X + (then) A  (admin cmd prompt)


Type the command:

wmic useraccount get name, sid
