0x80240034 error code during Windows update

The Windows Update error code 0x80240034 occurs relatively frequently and is referred to by Microsoft as ” WU_E_DOWNLOAD_FAILED “. Apparently the error occurs when downloading the Windows update and the following error message is then displayed.


Unfortunately, from the pure error message, there is no reason why the update error 0x80240034 occurs. However, you can take the following measures to eliminate the error.

Update Store Issues – 0x80240034

The most common reason for error 0x80240034 is a problem with the Windows Update Store. All updates are first downloaded in the update store and the installation is then started from there. Due to the large number of updates, it can happen from time to time that this update store becomes inconsistent and new Windows updates cannot be installed. The simplest is to delete the update store and have it rebuilt. Windows takes over this task completely independently if it no longer finds the directory structure of the update store . The following commands are necessary for this.

net stop wuauserv & net stop cryptsvc & net stop bits
ren C: Windows SoftwareDistribution SoftwareDistribution.xxx
ren C: Windows System32 catroot2 Catroot2.xxx
net start bits & net start cryptsvc & net start wuauserv

Below we have mapped the entire process again.

Rebuild Windows Store

After the Windows Store has been completely reset, you can restart the Windows Update function and check whether the Windows update error code 0x80240034 is still occurring.

Remove WSUS server entries

A Windows Update Services Server (WSUS) can also cause error code 0x80240034 . This usually affects PCs that are in a company environment or have already had contact in a company network. Then it may be that the WSUS server information is stored in the registry and trigger the problem. You can check this relatively easily by calling the Windows Registry Editor (regedit.exe) and changing to the following key.

Computer HKEY_LOCAL_MACHINE SOFTWARE Policies Microsoft Windows WindowsUpdate

There are 2 entries that are named as follows:


WSUS registry

If both entries contain an entry, as can be seen in the picture, you should remove these two values . Then restart the Windows PC so that the changes become active. Now the update error 0x80240034 should no longer occur.
