Unknown account appeared in my computer

Account unknown and a lot of numbers... What is it and why is it on my computer?

@OriginalUser556 

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
