Windows 10: 0x80240034 help me with update error

Update error code 0x80240034 I need help

:)

 

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.

 

error code 0x80240034

That is an update error:

WU_E_DOWNLOAD_FAILED - 0x80240034 - (52)

Update failed to download.

So something caused the update file download to fail... What is the question. Was it network related, or something on the computer.

I would start by downloading and saving the update to your drive before running it. If that doens't help, there are number of other relatively simple things we can suggest for you to try.
