Windows 10: KB4493440 will not install, error 0x80240034

I have a laptop where Windows Update had been stuck trying to install KB4493440 2019-04 Cumulative Update for Windows 10 Version 1709 since last year. It would repeatedly try then fail. I finally tried to sort this out, and while I have made progress, this update still shows up in the list and still fails.


It fails with error 0x80240034, and this is a summary of what I have tried so far:
1 Installing the update from https://www.catalog.update.microsoft.com/Search.aspx?q=KB4493440 was successful but did not remove it from the list in Windows Update. The Update History shows a successful install on the appropriate day, with later failed attempts to install it.

2 Updating Windows manually from https://www.microsoft.com/en-us/software-download/windows10 got the computer up to a current version, but did not resolve the issue with this update.

3 Following the steps at https://docs.microsoft.com/en-us/windows/deployment/update/windows-update-resources to run the 2 scripts for resetting Windows Update did not help. After rebooting, Windows Update detected the same update, which resulted in the same error.

4 Ran DISM and System File Checker, then rebooted. Still the same.


What else can I try?


Many thanks,

Shawn

Error updating windows 10, now there is a version
Version 1709
OS Build 16299.1127
I’ve already tried everything, even manually downloaded the update, it doesn’t work either. As well the KB4493440 update was installed and anyway Windows tries to install or download the same update. Despite the fact that the version of KB4493440 is installed
(when I start the manually downloaded version, it says that this update is already there because I downloaded it and tried to install it, but it turned out that this update was already installed, I deleted it and manually installed the update again) windows
update trying to install it again.
I even tried to delete KB4493440 and start the update again, everything went fine, Windows downloaded KB4493440 and installed the update with a restart of the computer, but when I started the update again it again tries to download KB4493440.

there is a screenshot in the attachment, the update was successful but again tries to install it. if you go to the Microsoft catalog there is only one version.

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). This tutorial explains the steps...

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.
