Dell Optiplex 3040 with Win10 Pro - Creator Update 1607 and 1703 will not install

This machine is not connected to a domain. It is in a homeoffice workgroup with full local admin rights.

The feature updates 1607 and 1703 will not install during Windows Update. They fail constantly. I tried downloading the standalone installers for them but they fail as well stating that they are "not applicable to this computer". I even downloaded the standalone installer for creator update 1709, which had not yet shown up in the customers Windows Update just see if it would work and it failed with the same message as well.

I've uninstalled the antivirus and tried the Windows Update reset procedures outlined on Microsoft support help article 971058 but same issue. Before resorting to reinstalling Windows I was hoping maybe someone here could shed some light on the situation. As a sidenote, all other Windows updates work fine. Its just those 3 that fail.

I know this is primarily a hardware forum but I posted here to confirm a claim from a tech who responded to this question when I posted it on Reddit claiming these creator updates were not compatible with these Dells which makes no sense to me.

Thanks in advance,

Adam
