Whether I use Windows Update or the Application Assistant, I get this same error.
Error message:
There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800703ee)

  • Antivirus and external drives disabled
  • Chkdsk returns no errors
  • There's plenty of space on C drive as well as in the EFI partititon
  • C drive has been cleaned up
  • All drivers have been updated
  • All Windows 11 requirements have been met

I'm not sure what else to try.

    Open admin Command Prompt and run:

    reagentc /info

    dir c:\windows\system32\recovery /a

    bcdedit

    diskpart

    list disk

    select disk 0

    list part

    list vol

    exit

    Post the output.

    Attach setupact.log, as mentioned earlier. You've uploaded setuperr.log instead.
