How to Fix 0x80240034 Error in Windows 10

0x80240034 The Windows 10 error is due to the fact that Windows Update is not able to download the different files.

that it needs to perform the updates required by Windows.

The error is specifically referred to as the "WU_E_DOWNLOAD_FAILEDerror, basically means that the system has not downloaded the correct Windows Update files.

The resulting problem means that your system is not able to handle the updates needed to run, which leads the system to display erroneous behavior.

To fix the problem, you basically need to fix all the main issues that prevent Windows Update from downloading the right files – this comes in the form of the ability to fix the likes of the Windows Update service and be able to repair one of the basic software applications that integrate with Windows.

How to Fix 0x80240034 Error

The error message will usually state the following:

Installation failed – 0x80240034

The causes of the error will usually be:

  • Internet connection problems
  • Microsoft Update Server Errors/Problems
  • Error with the update itself
  • Another different update error (maybe the virus/third-party software issue)

The way to fix the error is to make sure that the various files required by Windows Update are workingcorrectly. This can be done using the following steps:

1. Run Run Windows Troubleshooter

The first step is to run the Windows Update troubleshooter.

This is a tool associated with Windows 10 (and I believe Windows 7) that allows you to fix any issues that Windows may have with its basic "update" processes.


To do this, you can use the following steps:

  • Press the "Windows" + "I" keys on your keyboard (load the "settings")
  • Click on "Update & Security"
  • In the left panel, select "Troubleshooting"
  • From the list that appears, select "Windows Update"
  • Click "Run this troubleshooter"
  • Let the process work
  • Once done, restart your PC

This probably won't fix the error, but should fix most of the issues that arise with the update service.

2. Run SFC+ DISM

Once you have done the above, you need to run the SFC+ DISM commands.

These are small command-based applications in the Windows system, designed to provide users with the ability to fix most of the problems that form with Windows.

You can do this using the steps described here:

  • Press the "Windows" + "S" keys on your keyboard
  • Type "CMD"
  • In the first list that appears, right-click and select "Run as administrator"
  • In the black box that appears, type the following commands:
  • "SFC/skannow" + press "Enter"
  • "DISM / Online / Cleanup-Image / RestoreHealth" + press "Enter"

This will run a series of "scans" that will essentially ensure that your system is able to properly execute the various files/settings it needs.

While this certainly won't solve the problem (although it should be in 40% of cases), it should solve a large number of basic problems that can cause it to manifest.

3. Manually restart Windows Update

Then, you will need to manually restart the Windows Update service.

It's a bit tricky, but it should be the biggest contributor to a solution.


Basically, the way Windows Update works with what's called the "service."

This is an application that constantly runs in the background of your system and allows a number of other processes to use it at will.

The Windows Update service is responsible for downloading, restarting, and constantly updating the various items required to perform updates on Windows.

Unfortunately, it often happens that the system ends up having problems with the service, which can be solved by restarting manually:

  • Press the "Windows" + "S" keys on your keyboard
  • Tap on "CMD" and in the first article that appears, right-click and select "Run as administrator"
  • In the black box that appears, press the following commands:
  • 'net stop wuauserv' + 'Enter'
  • 'net stop cryptSvc' + 'Enter'
  • "stop sharp coins" + "Enter"
  • 'net stop msiserver' + 'Enter'
  • 'Ren C: Windows SoftwareDistribution SoftwareDistribution.old' + 'Enter'

Once you have done that, you will have to restart various services. This can be done using the following steps (again on the same CMD panel):

  • 'net start wuauserv' + 'Enter'
  • 'net start cryptSvc' + 'Enter'
  • 'bit neto start' + 'Enter'
  • 'net start msiserver' + 'Enter'

This should be tracked by running the Windows Update "Check for Updates" command again.

4. Temporarily disable the firewall/antivirus

Finally, one of the most common causes of the problem is a "false flag" on the part of your antivirus or firewall application.

This is due to the fact that your system basically thinks that (for some reason) the Windows Update service causes irregular (potentially dangerous) internet connections and will therefore block it.

To resolve this issue, you can use the following steps:

  • If you are using a TRET PARTY antivirus
  • Right-click on the security software icon at the bottom right of your Windows bar
  • Select the equivalent "pause" (this can be "Game Mode" / "Temporarily Banned" etc.)
  • Select "10 minutes" or equivalent
  • Try running Windows Update again
  • If the WU is not working at this point, try step 3 again with your temporary antivirus
  • Restart your system after this effort
  • If you are using Windows Defender (default antivirus)
  • Press the "Windows" + "I" keys on your keyboard
  • Select "Update & Security"
  • In the left menu, select "Windows Security"
  • Select "Virus and Threat Protection" and then "Virus and Threat Protection Settings"
  • Go to "Real-time Protection" in "Off"
  • Try updating the system and if it doesn't work – try step 3 again
  • After that, re-enable the Windows Defender service, restart your PC
