• Corrupt or Incomplete download of Windows update
• Missing registry entries

The error will disrupt your workflow and require that you attend to it as soon as possible. This article will show you how.

What Causes the Error Code 0x800b0003

The leading cause of the error code 0x800b0003 is outdated drivers. The error is an input-output error that indicates that the Windows OS has hit a snag and is unable to perform its duties as expected. Unattended to, the error will lead to your computer slowing down, system crashes and or cause your computer to freeze.

Clean Your Computer

The first thing that you want to do when you encounter an error such as the error 0x800b0003 is to clean your computer with a reliable PC repair, such as Outbyte PC Repair. The reason you would want to do this is that a PC repair tool will scan your entire system, find and repair any performance limiting issues that exist. It will scan for malware, repair registry entries, notify you of outdated software, and delete junk files. In most cases, cleaning your computer will be the only thing that you need to do to do away with the error 0x800b0003. But if that doesn’t work, you can pursue any of the following five solutions:

1. Update the drivers on your computer
2. Disable antivirus software temporarily
3. Launch Windows in Safe Mode
4. Perform System Restore
5. Scan for malware infection

1. Update the Drivers on Your Computer

It is always recommended that you keep the drivers on your computer up-to-date. The reason is that drivers enable communication between the software and hardware components on your computer and if they are not updated, corrupted or misconfigured, you might experience all kinds of issues with your PC. Here is how to update the drivers on your Windows computer:

1. Into the Windows search box, type ‘device manager’. This will lead you to the Device Manager app.
2. From the list of the devices listed on the Device Manager app, scroll to the ones that you want to update.
3. Right-click on each one of them and choose Update driver.
4. On the dialogue box that appears, click on Search automatically for updated driver software. Windows will then make the necessary updates.

To make the last step, you will need to have a stable internet connection. At the same time, you will have to manually check for the latest update for each of the devices that exist in your system. This, of course, can be very tiring, but there is a way out if you don’t want to make the changes yourself. Just download a utility tool such as Auslogics Driver Updater, and you will be good to go. The utility software will scan your system and make all the necessary driver updates with a few clicks of a button.

After updating the drivers on your computer, check if you are still experiencing the error 0x800b0003. If yes, try other solutions.

2. Disable Your Antivirus Software Temporarily

Although meant to keep your computer in good health, an antivirus program can also be a cause of many issues, including the error 0x800b0003. The program may, for instance, label the Windows installer file as spam and in the process, block many registry files.

To make sure that this is not the case, you will have to temporarily disable the antivirus software that is installed on your computer. These programs have a settings page that will allow you to disable them, although they will probably warn you that such action puts your computer at risk. You can ignore the warning for some time.

After disabling the antivirus program, you still have to disable the Windows Firewall. To do this, take the following steps:

1. Into the Windows search box, type ‘Firewall.cpl.’
2. Click on Windows Firewall.
3. Click on Turn Windows Firewall on or off.
4. Turn off Windows Firewall for both Private network settings and Public network settings.

Check if disabling your antivirus software and turning off Windows Firewall have helped resolve the error 0x800b0003. If not, below is another solution for the same issue.

3. Launch Windows in Safe Mode

In Safe Mode, Windows doesn’t run any third-party apps and operates using a limited set of drivers and apps. Safe Mode is thus great for diagnosing and fixing many security and performance issues on your computer. To launch Windows in Safe Mode, take the following steps:

1. Press the Windows + I keys on your keyboard to open the Settings app.
2. Go to Update & Security > Recovery.
3. Under Advanced Startup, choose Restart now.
4. Once your computer restarts, select Troubleshoot > Advanced Options > Startup Settings > Restart.
5. Once your computer restarts, press F4 or select Enable Safe Mode from the list of options that appear.

In Safe Mode, you can now work on your computer without expecting any errors.

4. System Restore

The System Restore option will return your computer to an earlier working state. But this is only possible if you already have a restore point on your computer. Assuming that this is the case, the following are the steps to take:

1. Into the Windows search box, type ‘system restore’. This will open the System Properties window.
2. Click on the System Protection tab.
3. Click System Restore.
4. On the System Restore wizard, click Next.
5. From the list of the restore points on your computer, choose the one that you prefer.
6. Click Next to see the programs and updates that are going to be affected by the System Restore process.
7. Click Next and Finish.

The System Restore process will remove any recent apps and updates that you might have installed on your computer and which may be responsible for the error code 0x800b0003 on Windows 10/11. System Restore is handy when you suspect that a recent update or software installation is responsible for the error 0x800b0003 when trying to install an app on your computer.

5. Scan Your Computer with an Anti-Virus Program

Viruses and other forms of malware may also be to blame for the error 0x800b0003. To make sure that this is not the case, scan your computer with a premium antivirus program to check if any form of malware infects your system.

If the error ox800b0003 persists, you should consider contacting Microsoft’s customer care or visit a PC repair clinic in your vicinity. You could also perform a clean install of Windows 10/11 on your computer or get the latest update from Microsoft.

No one likes receiving an error code when attempting to update his/her Windows operating system. However, update errors have become a part and parcel of Windows 11/10. In this post, we will discuss an Update error 0x800B0003 that occurs mainly when you are trying to download and install the latest cumulative update on your computer. 

In addition to that, we will also discuss what possibly could have triggered an error 0x800B0003 in Windows and what are the possible ways applying which you may overcome this scenario. 

If you are unable to download and install the latest security or non-security updates on your Windows PC, consider applying the below fixes one after another. 

• Troubleshoot Windows Update
• Disable Memory Integrity
• Disable External Antivirus Program
• Run SFC/DISM Scans
• Remove recently installed updates
• Perform a System Restore
• Manually download and install updates

1] Troubleshoot Windows Update

Troubleshooting Windows Update is an effective way to automatically detect unwanted settings that are preventing Windows Update from happening on its own. Attempt this fix and check if the error code 0x800B0003 resolves on your computer. Here’s how to proceed with this solution – 

• Go to Settings (Windows + I) and select System from the left sidebar. 
• Head over to the right pane and select Troubleshoot > Other troubleshooters. 
• Locate Windows Update under “Most frequent”, and hit the Run button available beside it. 

• Wait for the troubleshooter to launch and hit the Next button on it.
• Now, follow the on-screen instructions to find and resolve the underlying causes inside your operating system.

Note: If you are encountering the same error code on Windows 10, launch the troubleshooting tool by following these easy steps – 

• Press Win + I to launch Settings.
• Go to Update & Security > Troubleshoot > Additional troubleshooters. 
• Click once on Windows Update and when it expands, hit Run the troubleshooter. 

Wait for the troubleshooting tool to start and when it does launch, click Next and follow the on-screen instructions that come moving forward. Hopefully, the error code 0x800B0003 is resolved in this step alone. If not, try the next set of solutions discussed below. 

2] Disable memory integrity in Windows Security

Several users reported fixing this error code 0x800B0003 after they disable the Memory Integrity under Windows Security. Here’s how to proceed ahead with this task on Windows – 

• Press Windows + S, and search for Windows Security in the text field.
• Click on the top result and when it does open, select Device Security from the left sidebar. 

• On the right pane, locate and click Core isolation details. 

• Under Core isolation, you will find a toggle switch next to Memory integrity. 
• When you turn off this toggle switch, the UAC window will prompt next.
• Click Yes to authorize disabling Memory integrity on your computer. 

• This change requires you to restart your device. So, close all running windows and restart your computer.

Sign back into your device again and check if you can update Windows normally now. 

Note: After you update your operating system, make sure to turn On this Memory integrity feature under Windows Security. Otherwise, your device will be prone to malicious attacks entering high-security processes. 

3] Disable External Antivirus Program

If you use some external antivirus programs to protect your system against malware or ransomware attacks, you should uninstall or temporarily disable that security application. External software is known to interact with the system files and make them corrupt. Over a period of time, such files prevent installing new updates on your computer.

Note: In case you are using some freely available antivirus application, we suggest switching to Windows Security on your computer. Windows Defender is a far superior application when compared to such freebies. Moreover, this is an internal application and hence is compatible with different processes and services on Windows. 

4] Run SFC/DISM Scans

The presence of corrupt system files and folders may also prevent Windows Update from happening and instead throw an error code 0x800B0003. Run System File Checker to check if there is indeed some corruption within your system files or folders. Here’s how to initiate an SFC scan in Windows – 

• Press Windows + X, and select Terminal (Admin). 
• By default, the terminal lands into Windows PowerShell having administrative privileges. 
• Copy/paste the following code on it and press Enter – 

sfc /scannow

• Wait for this code to finish scanning/repairing all system files and folders. 
• After this is over, run the DISM tool to check and resolve any corruption within the System Image as well. 
• For this, you need to run the following code on an elevated console – 

dism /online /cleanup-image /restorehealth

• Wait again for the next 10-15 minutes for the DISM tool to finish its scanning/repairing process. 
• After this is over as well, close the terminal, and restart your computer.

Hopefully, you should now be able to update your operating system to its next available Build version. 

5] Remove recently installed Windows Updates

If you have recently installed some cumulative update on your computer and this error code 0x800B0003 started occurring afterward, you must have installed a buggy update. In that case, you should remove that particular update from your system and check if the problem resolves this way. Here’s how to uninstall a recent update from Windows 10. 

Windows 11 users may follow these steps instead – 

• Press Windows + I to launch Settings.
• Go to Windows Update from the left sidebar and select Update history under More options. 

• Scroll down to the bottom and click Uninstall updates under Related settings. 

• Locate the update after installing which, this error 0x800B0003 started occurring. 
• After you find the buggy update, click the Uninstall button available on its right-end. 

• The system will confirm next if you really want to remove the selected update from your system. 

Well, click Uninstall again and wait for the next 10-15 minutes while the system is uninstalling the chosen update. Your device may restart a few times during this whole process, so wait patiently. After this is over, restart your computer again and check if you can install new updates on your Windows PC from the subsequent login. 

6] Perform a System Restore

There are times when you can’t remove a cumulative update from your system manually. If that’s the case, you may use the last restore point to revert back your PC to its earlier stable state. 

If you haven’t created a system backup ever on your computer, skip to the next solution. Else, read this article on how to use a system restore point on Windows 11/10. 

7] Manually download and install pending updates

Since you are here, the above solutions must not have worked in your favor. Worry not, as you can always download the relevant standalone package of a recent cumulative update from Microsoft’s Update Catalog and install that manually on your PC. Here’s a guide on how to proceed with this solution on Windows 11 or Windows 10. 

Why Windows Updates are essential?
