Windows 10: PERMISSION FROM S-1-5-21-210475555-2911152858-2912198334-1002

I created a new account because I wanted to change user folder name on my pc. Did all the necessary stuff but mistakenly deleted the new local account that I created and set as administrator. Now I want to clear the new account folder from my pc but to no avail. Any help?

I'm trying to delete a file, it requests administrator permission, I give it, but it says I still need permission? How do I fix this?

This computer was recently sent away for repair, and I've spent most of today setting it up. Whilst trying to delete a folder as part of re-installing a game that didn't install correctly, I was told I needed administrator permission to delete the file.

I have done this exact same thing multiple times before on the computer before it was sent away, but this time I got another popup saying I needed permission from "S-1-5-21-78511333-3158199425-1353651091-1002" in particular.

I have no idea who or what "S-1-5-21-78511333-3158199425-1353651091-1002" is, but I worry I'm not considered an admin on my own computer.

What happened, and is there any way to fix it?
