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?
