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 Download Windows 10 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 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

Aditya,

1709 OS build 16299.1127

HP elitebook8470p

no extra virus/security

I tried the two things you suggested. After a reboot, it detected the same update, was unable to install it, and still gives error 0x80240034.

Thanks

Shawn
