I cannot update my system.it keeps saying failed no matter how many times i press retry

i think it wasnt successfull cause it displays an error after i type the command.

Thanks for the clarification.

I suspect a corruption issue.

In this case, use the system file checker to try to repair possible corrupted system files.

1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
2. Run the following commands at the Command Prompt one at a time:

dism.exe /online /cleanup-image /scanhealth

dism.exe /online /cleanup-image /restorehealth

dism.exe /online /cleanup-image /startcomponentcleanup

sfc /scannow

Note: Pay close attention to the results of the commands. This will help you determine whether the procedure was completed successfully or if there was a problem. If you get any errors, let me know the error message that was displayed.

3. Then restart your PC and see if you can update.

If the problem persists, let me know, and I will provide another method. Click on the "Reply" button below my reply.

the troubleshooter didnt work

Thanks for the clarification.

You have found the cause of the issue.

Although it looks like a permissions issue, it is most likely a corruption issue.

However, I suggest trying the Windows Update Troubleshooter if you haven't already tried. It may give more clues or even fix the problem.
