I am trying to update to the latest version of Windows. The downloading is successful, so I restart my computer. After the first reboot, it starts restoring back to my previous version of Windows. Then, I tried using the Windows ISO. Again, the downloading
was successful, so I restart my computer. After the first reboot, it again goes back to my previous version of Windows. Then the ISO opens and displays the error code 0x8007001F - 0x20006. Please help!
I can not update using Settings or the ISO!

Run the SFC command when troubleshooting a buggy Windows system. SFC works by scanning for and replacing system files that are corrupt, missing, or changed. Even if the SFC command doesn’t repair any files, running it will at least confirm that no system files
are corrupted and then you can continue to troubleshoot your system with other methods. You can use the SFC command as long as the computer itself will start. If Windows will start normally, you can run it from an administrative command prompt. If Windows
won’t start normally, you can try starting it in Safe Mode or in the recovery environment by booting from your installation media or recovery disc.
If after executing the steps of the previous link, you try to update again, if it does not work, check these other links.
