What Causes Windows Update Error Code 0x80240034?

Several issues can trigger Windows Update Error Code 0x80240034, including:

• Unstable or restricted internet connections

How to Fix Windows Update Error Code 0x80240034

1. Check Your Internet Connection

Windows needs a stable internet connection to download update files. First, check whether other websites or online services work normally.

Restart your router if necessary. You can also disconnect and reconnect to your network.

If possible, try a different network. Then open Windows Update and check for updates again.

If you continue to experience connection-related Windows Update problems, see our guide to Windows Update Error Code 0x8024402C for additional troubleshooting steps.

2. Free Up Disk Space

Windows may fail to download or install an update when the system drive has very little free space.

Open Settings > System > Storage and check the available space on your Windows drive.

Remove unnecessary temporary files, empty the Recycle Bin, and uninstall applications you no longer use. You can also move large personal files to another drive or external storage.

After freeing up space, restart your computer and try Windows Update again.

3. Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter that can detect common update problems.

On Windows 11:

1. Open Settings.
2. Select System.
3. Select Troubleshoot.
4. Open Other troubleshooters.
5. Find Windows Update.
6. Select Run.

On Windows 10, open Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.

Follow the instructions on screen. Then restart your computer and check for updates again.

4. Run System File Checker

Damaged Windows system files can interfere with the update process. System File Checker can scan Windows and repair certain corrupted files.

1. Open Command Prompt as an administrator.
2. Enter the following command:

sfc /scannow

3. Press Enter.
4. Wait for the scan to reach 100%.
5. Restart your computer.

If Windows reports that it found and repaired corrupted files, try Windows Update again.

5. Run the DISM Tool

If SFC does not resolve the problem, use the Deployment Image Servicing and Management tool.

Open Command Prompt as an administrator and run these commands one at a time:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Wait for each command to finish before running the next one.

After the final command completes, restart your computer. Then check Windows Update again.

6. Restart Windows Update Services

Windows Update depends on several background services. A temporary service problem can prevent updates from downloading or installing.

Press Windows + R, type:

services.msc

Press Enter.

Find Windows Update in the list. Right-click it and select Restart.

Also check the Background Intelligent Transfer Service (BITS). If it is stopped, start the service.

Afterward, restart your computer and try the update again.

7. Reset Windows Update Components

If Windows Update files have become corrupted, resetting the update components can help.

Open Command Prompt as an administrator and run:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Then rename the Windows Update folders:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 catroot2.old

Now restart the required services:

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Restart Windows and check for updates again.

8. Temporarily Check Security Software

Third-party antivirus or firewall software can sometimes interfere with Windows Update.

If you recently installed or changed security software, temporarily check whether it is blocking the update.

Do not leave your computer unprotected. Re-enable your security software after testing.

You can then try Windows Update again.

9. Update Your Device Drivers

Outdated or incompatible drivers can sometimes interfere with Windows updates.

Open Device Manager and check devices with warning icons. Update the affected drivers through the device manufacturer’s official support channel.

Restart your computer after installing driver updates.

10. Try Windows Update Again

After completing the troubleshooting steps above, open Windows Update and check for updates again.

On Windows 11, go to Settings > Windows Update.

On Windows 10, go to Settings > Update & Security > Windows Update.

Install any available updates and restart the computer if Windows requests it.
