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.

    1. Run the following fixlist.

    Post the latest fixlog.txt.

    1. Update the BIOS and device drivers for your PC.
    2. Enable Memory Integrity. To do so, go to Windows Security > Device security > Core isolation details > Memory integrity. If it shows any incompatible drivers, post the screenshot here.

    Farbar scan:

    Please run this fixlist.

    • Download fixlist.txt
    • Save Fixlist.txt to the same folder as FRST64.exe.
    • Close all programs.
    • Launch the Farbar Scanner tool and click "Fix".
    • Restart Windows when prompted.
    • Upload the output log file (FixLog.txt) to your OneDrive.

    NOTE: The fixlist.txt script was written specifically for this user and for use on that particular machine. It is not recommended to run it on another machine, and don't run the same fixlist.txt more than once.
