Windows 10: Trying to upgrade to version 1803, and always fails in Windows Update

I'm looking for suggestions for how to proceed. I have an older Toshiba laptop that has been working pretty well with Win 10 ver. 1709 on it for quite a while. I think for as long ago as since last summer, it has been trying to upgrade to version 1803, and always fails in Windows Update. I decided to try using a DVD I have with 1803 on it, and do an In-Place Upgrade, thinking this would overcome the problem. It goes pretty far into the upgrade (over 1/2 hour, at least 37%), and then fails with a simple message that the installation has failed.

I tried it again after doing a disk cleanup of system (old install) files, but it still fails. Admittedly, I am using an older CD I had with 1803 on it. I would like to keep my files and setup. What should I try next? Should I download a fresh ISO of 1803, or one of 1709 (followed by a more recent version), or 1809--which of these will have a better chance of getting a good in place upgrade? Or should I use the built-in download to do a "system refresh"? Otherwise, I am kind of stuck, and it seems like I would have no option but to do a completely fresh install--and then to which version?? I'd rather not have to reinstall all my files and programs, but obviously would have to with a fresh install.

Also, I have most of my files segregated on a separate D: partition. Can i just leave that there if I do a fresh install?

Update version 1803 (3) always fails with error 0x80240034

That error code means the download could not complete successfully....

In such cases, an in-place upgrade using an ISO made by Microsoft's Media Creation Tool should succeed where windows update fails. Note that the MCT now makes install media for the current version which is 1809. That should not be a problem and would be the version I'd use in your place (and am using on my PC).

But if you really insist on upgrading to 1803 you'll need to use an 1803 ISO. This 3rd-party tool from Heidoc can generate a link to get one direct from Microsoft.
