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 Microsoft Update Catalog 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 Windows Update - Additional resources - Windows Deployment | Microsoft Docs 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

Hi Shawn,

Thanks for your response.

Check the package details tab and check for the section “This update has been replaced by the following updates:”
in this catalog details:
2019-04 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4493440)

If a later or replacement version of update is installed, then you can hide this update.
