Windows 10: I'm trying to delete a file, it requests administrator permission, I give it, but it says I...

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?

Deleting a file that requires permission from Administrator

I'm trying to delete a file that keeps telling me I need permission to perform this action. I require permission from Administrators to make changes to this file.

Now if I look under User Accounts on the control panel there is only ONE account listed: mine as administrator.

However, under the properies window for the file there are three:

SYSTEM

Administrators (DJ Hernandez\Administrators)

Users (DJ Hernandez\Users)

The first two are listed as Full control on the Permissions tab of the Advanced Security Settings for the file. The Users is listed as Read. All three under Inherited From have C:\Program Data\Avg\Antivirus\

Is there any way that will allow me to get rid of this file? This belongs to a program that I have deleted using the Control Panel but it still shows up in the program listing under Programs and Features of the Control Panel.

 

You'll need to provide administrator permission to copy this file

Hi,

Follow the Steps below and check if that helps.

As you are unable to transfer some files from an external hard drive to the computer requesting for Administrator permissions, I suggest you to follow the steps provided below to provide administrator permissions to the particular folder and check if it
helps.

• Right click on the folder and select
  Properties.
• Click on Edit button in Properties windows. Click ok to confirm UAC elevation request.
• Select user/group from permission windows or click
  Add to add other user or group.
• Now under Permission section check the rights which you want to grant i.e. check “Full Control” under the “Allow” column to assign full access rights control permissions. (Generally we add ‘Everyone’ to given permission to all
  the users on the computer).
• Edit the permission to Full Control for ‘Everyone’.
• Click OK for changes to take effect and click ok again to exit from Properties window.

Do let us know if you are able to transfer files to PC. Thank you.

 

Can't Delete Corrupted File - All Permissions Removed


So I have a file in my downloads that somehow got corrupted and all the permission information on the file is gone. I can't delete as it says I need permission to delete it. When I try to forcefully delete it through cmd as administrator, I get "Access denied". I've tried using an unlocker tool as well as taking ownership of the file but everything has failed.

Any other suggestions?
