Error 0x8007042B normally appears while performing a Windows update on the computer. This problem may arise due to different reasons like corrupted system files or Windows Image, the BITS service not running in the background, or the presence of a third-party antivirus program.
How to Fix Windows Update Error 0x8007042B
Here, we have covered six working ways that may resolve the 0x8007042B error on the computer. Just make sure to proceed in chronological order.
1. Disable Third-Party Antivirus
Antivirus programs from third parties are known for interfering with system files, resulting in errors and bugs. In such cases, you should disable the software until the update is completed. Then, you should restart the device so that the changes take effect.
In fact, you don’t need any external software to protect your PC from viruses or malware. The reason for this is that Microsoft provides a great in-built tool for this, i.e., Windows Defender. To use this program, you simply need to start it and have it updated to the latest version. This includes all the features or more that you get from free antivirus software from a 3rd party.
2] Run Windows Update Troubleshooter
If you continue to receive the 0x8007042B error, run the Windows update troubleshooter. This tool will check for potential causes and resolve them.
For Windows 11
1. Open the Windows Settings using the Windows+I keys.
2. Click on System > Troubleshoot > Other troubleshooters.
3. Go to the Windows Update and click on the Run button.
4. Follow the on screen prompts to complete the procedure.
For Windows 10

3. Perform DISM and SFC Scan
A corrupt Windows Image may also result in the 0x8007042B error and so do the damaged system files. This is why we suggest performing DISM and SFC scans to rule out the system-level corruption.
1. Open Command Prompt as an administrator.
sfc/scannow in the prompt area and hit Enter.
3. This usually takes 20-25 minutes to complete the whole scanning/repairing process.
4. Once over, restart your PC and check whether it solves the issue or not.
After you run the System File Checker tool you now need to run the DISM tool. So follow the below procedure to do this:
1. Open the command prompt having administrative privileges.
2. Now type the below command line and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
This code will look for any inconsistencies inside Windows and resolve them.
4. Restart BITS Service
Sometimes, the update process fails on 0x8007042B error owing to internal services not running properly. BITS is one such service that must run supporting the download of Windows updates in the background. If you are getting this bug time and again, check the current status of the BITS service.

2. Right-click the top result and select Run as Administrator.
3. Scroll down and double-click Background Intelligent Transfer Service to enter its properties window.
4. Set the Startup type to Automatic (Delayed) and click Apply > OK.
5. Click Stop to temporarily stop this service, then click Start again to restart it.
6. When the BITS service restarts, restart your comptuer.
5. Use System Restore Point
If you have previously created a system restore point on your computer, you may attempt running this backup. All you require is to follow these simple steps.
1. Press Win + R to start the Rin dialog.
2. Type rstrui in the text field and hit Enter.
3. Click Next then choose the lately created restore points.
4. Click Next > Finish to start reverting the operating system to its previous state.
6. Manually Install Windows 10 Updates
If all of the above methods fail to resolve the 0x8007042B error, try manually updating your Windows to its latest Build version. To do so, follow the below steps –
1. Go to the Windows 10 Update History webpage.
2. On the left pane, select Windows 10 feature update that is currently running on your PC.
Note: If you don’t know about which feature update you are currently having, go to Settings > Update & Security > Windows Update > OS build info. Now, look what’s there against the version under the Windows Specifications section.
3. Scroll further below and select the top result under the “In this release” section.
4. Note down the cumulative update number starting with “KB” such as – KB4571756.
5. Next, go to the Update Catalog and copy/paste this number in the search field.
6. Click Download next to your PC architecture like 32-bit, 64-bit, ARM64, etc.
7. Hit the top link containing
.msu file to start downloading this update.
8. When the download completes, reach out to the download folder, and double-click the setup file.
Note: Since doing this automatically updates your operating system to the latest version, there’s no need to update Windows 10 again.
The error 0x8007042B should not occur while updating to the next build version release. In case this appears again, you may re-follow this method or simply clean install Windows 10 on your computer.
