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.

    Here it is. I'm not sure you wanted to format. It's like 100MB.

    Looks like the format command failed.

    Please try this:

    • format W: /fs:FAT32
