Fix: Windows 10 update error 0x803c0109




While Windows 10 should be a certain upgrade over its predecessors, it inherited few common issues. Additionally, with Microsoft cutting off support for previous systems, Windows 10 becomes the only viable option in the upcoming years.

The majority of errors is somehow connected with updates and all of them can manifest different issues. One of those errors that commonly appear after updates, bears the code 0x803c0109. As some users reported, this issue affects sound and sound device drivers. The main culprit is a failed update or a defective build. However, don’t worry, because we have a few workarounds that should resolve this annoyance, in case it bothers you.

How to fix error 0x803c0109 on Windows 10

Table of contents:

1. Check Speaker Properties

Your first step should be checking sound devices and connect them to an alternative source. Additionally, some updates can change your settings, so follow these steps and make sure everything is set as it’s supposed to be.

That should resolve all potential issues with the Speaker settings. However, if the problem is persistent, move on to the next step.

2. Reinstall Driver Manually

As you might be aware of, Windows 10 Update will occasionally install a few drivers on your PC, too. In some cases, that can be a good thing. However, more time than not, the generic drivers are not the best solution. So, you’ll probably need to uninstall Sound drivers and get the new ones from the manufacturer’s official site. In order to do that, follow these instructions:

2.1 Update drivers automatically

In order to prevent PC damage by installing the wrong driver versions,  we strongly suggest to do it automatically by using a third-party tool.

An automatic tool will help you update all outdated drivers safely. After several tests, our team concluded that this is the best-automatized solution:

Sometimes, malfunctioning drivers can cause multiple system errors.

If this happens to your PC, you may need to update or reinstall certain drivers entirely. As the process is not quite straightforward, we recommend using a reliable driver updater for the job. Here’s how to do it:

Download and install Outbyte Driver Updater.

Launch the software.

Wait for the app to detect all faulty drivers.

Now, it will show you all the malfunctioning drivers listed to select the ones to Update or Ignore.

Restart your PC to ensure the applied changes.

Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.

3. Restart Update Services

As we already stated, the previously installed updates are the reason for sound issues. At least, most of the time. Due to corrupted or incomplete updates, you can experience performance drops or malfunction of certain peripheral devices. This is how you can try and fix updates in the first place:

That way you’ll make sure that the main update service is working. Try updating and see is the problem maybe resolved.

4. Check system integrity with SFC

Additionally, if the updated system files are corrupted or incomplete due to malware or misuse of any kind, various errors can occur. However, you can solve that in a few easy steps with the SFC tool. And this is how:

Hopefully, after that, you’ll be able to install new updates and possibly fix the sound issue.

5. Uninstall previous updates

Expert tip:

Most of the time, Microsoft address this issues, so you can expect a fix with the upcoming updates.

6. Run DISM

If running the aforementioned SFC scan didn’t get the job done, you can try with DISM. Deployment Image Servicing and Management is a command-line tool that deploys the system image all over again. Maybe this process will help with updating problems.

Here’s how to run DISM in Windows 10:

Open the Command Prompt as shown above.

Enter the following command and press Enter:

 /Online /Cleanup-image /Restorehealth

Wait for the process to finish.

Restart your computer.

In case the DISM can’t obtain files online, try using your installation USB or DVD. Insert media and type following command:

 /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Make sure to replace ”C:RepairSourceWindows” path of your DVD or USB.

Follow further on-screen instructions.

7. Run the Update troubleshooter

We mention Windows 10’s built-in troubleshooter in almost every article. And that’s for a reason. Microsoft introduced this tool to automate troubleshooting in Windows 10 and make it easier for end-user. As the troubleshooter offers solutions for various problems, we can use it for resolving update issues, as well. Hopefully, the system will recognize what’s wrong and resolve the issue for us.

Here’s how to run Windows 10’s built-in troubleshooter:

8. Restart Update components

If the troubleshooter failed to resolve the problem, we’ll have to go back to our own. So, the next thing we’re going to do is resetting crucial Windows update components, in order to get them back to a (hopefully) working state. Here’s what you need to do:

Start Command Prompt as administrator.

When Command Prompt starts, run the following commands:

net stop wuauserv

net stop cryptSvc

net stop msiserver

ren C:WindowsSoftwareDistribution chúng tôi C:WindowsSystem32catroot2 chúng tôi start wuauserv

net start cryptSvc

net start msiserver

9. Make sure the BITS service is running

Background Intelligent Transfer Service (BITS) is a key service for delivering Windows updates. So, the first thing we’re going to do is restarting it. This should help to eiminate any possible interferences. After that, we’ll enable the service and make sure it stays on.

Here’s what you need to do:

10. Disable antivirus

Third-party antivirus programs and Windows updates are not designed to work in harmony. Because of that, it’s quite possible for your antivirus to block the incoming update. To eliminate the doubt, disable your antivirus for a few minutes, and try to install updates once again. If you succeed, the problem is resolved. If not, well…

11. Install the update manually

And finally, if none of the previous solutions managed to resolve the problem, we’ll have to surrender and install the update manually. Here’s how:

Copy the name of the issued file.

Go to Microsoft Catalogue here.

Paste the name into the search box.

Download the file. Keep mind on your system architecture (x86 or x64).

Install the update file.

Restart your PC.

Check for additional updates to make sure the update is up and running.

That is it. We hope you’ll manage to get your sound back and resolve additional issues.

For more Windows Update workarounds, and additional info, make sure to check our Windows Update hub.

Fix Windows Update Error 0X8024A203 On Windows 11/10

Windows Update is a very useful service that provides a platform for updating the operating system. It helps to ensure that your device is running with the latest features and security updates. However, some users have recently encountered error code 0x8024a203 when they run the Windows Update on their computers. In this post, we have covered some quick and easy solutions that could help you resolve this issue. Now, let’s find out how to resolve it.

Fix Windows Update Error 0x8024a203 on Windows 11/10

Despite the newness of the Windows operating system, users are experiencing multiple problems with it. One of these errors is 0x8024a203, which occurs during the updating of Windows. At this point, the user is unable to download and install the latest Windows update. In case you’re facing the same problem as us, do not worry, we’ve come up with a list of effective solutions to help you with it.

Run Windows Update Troubleshooter

Delete the Temporary Files

Run SFC and DISM tool

Reset Windows Update Components

Manually download and install updates

Let’s now see them in detail.

1] Run Windows Update Troubleshooter

Microsoft Windows comes with various types of troubleshooting tools that can be used to fix various kinds of problems. When you encounter a Windows Update error, you should run the Windows Update troubleshooter first. You can do this by following these steps:

For Windows 11

Open the Windows Settings. For quick access to the Settings app, use the Windows+I keyboard shortcut.

On the left side of the screen select System.

When the troubleshooting process is complete, the problem might be resolved.

For Windows 10

Launch the Windows Settings.

Once you have done this, check if the issue persists.

2] Delete the Temporary Files

If you experience trouble installing Windows updates, you can clear your temporary files and cache. After clearing them, restart your computer and check if it works.

3] Run SFC and DISM

The System File Checker (SFC) is a tool that users can use to detect and restore corrupt system files. If you’re experiencing this problem, it seems some of the files needed for Windows Update are damaged, altered, or missing. In order to restore missing or corrupt system files, you can use System File Checker, followed by Deployment Image Servicing and Management (DISM).

Follow the below instructions to run SFC and DISM:

Run the Command Prompt as an administrator.

Type in sfc /scannow and press Enter.

Wait a few minutes for the procedure to complete. While the system is scanning the code, you can perform any other task you wish.

Once it completes the scanning process, restart your computer to see if it works.

If that doesn’t resolve the problem, run DISM to repair the corrupted Windows Update files.

Copy and paste the following command into the elevated Command Prompt window and press the Enter key:

DISM.exe /Online /Cleanup-image /Restorehealth

Once this is done, restart your computer and the problem should be resolved.

However, if your Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files.

You will then be required to run the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Here you have to replace the C:RepairSourceWindows placeholder with the location of your repair source.

Once the process is complete, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.

Close the command prompt, and then run Windows Update again and see it has helped.

4] Reset Windows Update Components

This problem can also happen if some type of corruption occurs in your system files. Hence, if you are still experiencing a problem after running the SFC and DISM utilities, you can reset the Windows Update Components and see if it works. Here is a guide to help you do this:

The first thing you need to do is run the Command Prompt as an administrator.

To do so, press the Windows key + R to open the Run dialog box.

In the text field, type in cmd and press Ctrl+Shift+Enter keyboard shortcut.

Once it opens the Command Prompt, type the following commands. After typing each command, press Enter:

net stop bits net stop wuauserv net stop appidsvc net stop cryptsvc

In this case, the Background Intelligent Transfer Service (BITS), Windows Update service, and Cryptographic service will stop working.

It is now time to reset Windows Update components by deleting all qmgr*.dat files from your computer.

To do this, type the below command line in the command prompt and hit enter.

Del "%ALLUSERSPROFILE%Application DataMicrosoftNetworkDownloaderqmgr*.dat"

Afterward, type Y on your keyboard to confirm the deletion.

Next, you should rename the SoftwareDistribution and catroot2 folders.

To do this, run the following commands in the command prompt window. Don’t forget to press Enter after typing each command.

Ren %systemroot%SoftwareDistribution SoftwareDistribution.bak Ren %systemroot%system32catroot2 catroot2.bak

After you have done this, you need to reset both BITS and Windows Update services to their default settings.

To do this, type the below commands in the elevated command prompt window:


To execute the commands, press Enter after each one.

In the command prompt window, type the following code to move to the System32 directory. Press Enter to continue.

cd /d %windir%system32

Type the following commands, and be sure to hit enter after each command.

regsvr32.exe atl.dll regsvr32.exe urlmon.dll regsvr32.exe mshtml.dll regsvr32.exe shdocvw.dll regsvr32.exe browseui.dll regsvr32.exe jscript.dll regsvr32.exe vbscript.dll regsvr32.exe scrrun.dll regsvr32.exe msxml.dll regsvr32.exe msxml3.dll regsvr32.exe msxml6.dll regsvr32.exe actxprxy.dll regsvr32.exe softpub.dll regsvr32.exe wintrust.dll regsvr32.exe dssenh.dll regsvr32.exe rsaenh.dll regsvr32.exe gpkcsp.dll regsvr32.exe sccbase.dll regsvr32.exe slbcsp.dll regsvr32.exe cryptdlg.dll regsvr32.exe oleaut32.dll regsvr32.exe ole32.dll regsvr32.exe shell32.dll regsvr32.exe initpki.dll regsvr32.exe wuapi.dll regsvr32.exe wuaueng.dll regsvr32.exe wuaueng1.dll regsvr32.exe wucltui.dll regsvr32.exe wups.dll regsvr32.exe wups2.dll regsvr32.exe wuweb.dll regsvr32.exe qmgr.dll regsvr32.exe qmgrprxy.dll regsvr32.exe wucltux.dll regsvr32.exe muweb.dll regsvr32.exe wuwebv.dll

Running the above commands will re-register all the respective BITS files and Windows Update related DLL files

Your next step should be to reset the network configurations that may have contributed to the problematic error.

In order to do that, run the below commands:

netsh winsock reset netsh winsock reset proxy

After you have done this, it’s time to restart the services you stopped earlier, such as Background Intelligent Transfer Service (BITS), Windows Update, and Cryptography.

For this, open the Command Prompt and run the below command line. You must press Enter after each command.

net start bits net start wuauserv net start appidsvc net start cryptsvc

Now close the Command Prompt window and restart your computer.

When your PC starts, go to Windows Updates and see if you can install the pending updates

5] Manually download and install updates

When none of the above solutions resolve the problem, you can try downloading and installing the update manually from the Microsoft Update Catalog and see if that helps.

How do I fix the Windows Update assistant error?

In case you’re having issues with Windows Update Assistant on your computer, you can use the following steps to fix the issue. Restart the Windows Update Service. Run the Windows Update troubleshooter. Temporarily turn off the Third-Party Antivirus program and Windows Defender. Clean up the update cache.

What does Windows Update do?

Fix: ‘Display Not Compatible’ Error Prevents Windows 10 Anniversary Update From Installing

Fix: ‘Display not compatible’ error prevents Windows 10 Anniversary Update from installing






Try Outbyte Driver Updater to resolve driver issues entirely:

This software will simplify the process by both searching and updating your drivers to prevent various malfunctions and enhance your PC stability. Check all your drivers now in 3 easy steps:

Download Outbyte Driver Updater.

Launch it on your PC to find all the problematic drivers.

OutByte Driver Updater has been downloaded by


readers this month.

It’s been almost a week since Microsoft finally released the Anniversary Update to Windows 10 users. The update brought a lot of interesting new features and additions, we talked about it a lot lately, but it also caused a big number of issues to users who installed it, as well.

In this article, we’re going to talk about a single issue that is not actually caused by the Anniversary Update but rather prevents it from installing. This issue is an error message saying that people can’t download the Anniversary Update, because their display isn’t compatible.

Many users reported this issue on Microsoft’s Community forums, so we assume there could be a lot of people with this problem

This could be a serious issue for some users because they’re not able to install the latest update. So, let’s see what might actually cause this issue, and how we can solve it.

Your screen, just like every other hardware in your computer requires a driver to work properly. What could be a problem with major updates for Windows 10 is that some drivers aren’t compatible with them.

Drivers may work properly in a current version of Windows 10, but they may need to be updated when the major update, in this case the Anniversary Update, arrives.

So, before you try to install the Anniversary Update, make sure all your drivers are compatible with it. In case you’re not sure how to do that, follow these instructions:

If, however, there was no new update for your current driver, your display itself is probably compatible with the Anniversary Update (but to make sure, check out the Anniversary Update system requirements).

There’s probably some other driver that prevents the update from being installed on your computer. 

We also recommend a third-party tool to automatically download all the outdated drivers on your PC. Using this specialized driver updater tool, you can manage all your drivers with automated support for fixing or updating any driver. 

Expert tip:

Lastly, using third-party software like this you stay secure from system malfunctions caused by drivers’ incompatibility with your hardware devices. 

⇒ Get Outbyte Driver Updater

Solution 2 – Uninstall mirror drivers

There’s a big chance that some driver, that is not directly related to your display is actually blocking the Anniversary Update from being installed. In most cases, these drivers are mirror or remote controller drivers. Some of these drivers are Cyberlink Mirror, LogMeIn Mirror, a ‘Mirage Driver,’ and more.

So, try to uninstall whichever driver you suspect might be of this kind, and you should be able to install the Anniversary Update without any problems. If you’re not sure how to do that, do the following:

Once you uninstall a mirror driver, try to install the Anniversary Update once again, and you should have no problems. This is actually a solution that most people confirmed is working, so it’s very likely that it will also work for you.

If nothing from the above worked, you can always try installing the Anniversary Update manually, and not via Windows Update. Installing the update manually can actually solve a lot of problems, because it is treated as a clean install, and doesn’t involve the updating process.

Since ISO files for Windows 10 Anniversary Update are now available, you can easily create a bootable media, and perform a clean install on any computer. 

If you don’t know how to create bootable media with the Anniversary Update and perform a clean install, check out this article.

That should be all, performing at least one of these solutions will probably solve the problem. But once again, the second solution is perhaps the best option, as it was helpful for most people.

Fix 0X80243Fff Windows Update Error The Right Way

This post explains how to fix Windows Update error 0x80243FFF. Error 0x80243FFF is a system-level error that occurs during an automatic Windows Update. The complete error message says:


There was a user interface error not covered by another WU_E_AUCLIENT_ error code.

The error may occur due to generic unexpected UI [AU Client] failures, file corruption while the update was downloading, or a malware attack on a Windows system. It may also occur when an automatic update received from Microsoft doesn’t work.

If error 0x80243FFF prevents you from installing an update patch on your Windows 11/10 PC, keep reading the post to know how to fix the error.

Fix 0x80243FFF Windows Update error the right way

Use the following solutions to fix the 0x80243FFF Windows Update error:

Run Windows Update troubleshooter.

Repair Windows Update client using DISM.

Reset Windows Update Components.

Install Windows Update in Clean Boot.

Download Update manually and install it via the Catalog website.

Let us see these in detail.

1] Run Windows Update troubleshooter

Start by running the Windows Update troubleshooter. It will identify any problems that may be preventing your system from downloading or installing the update, and attempt to fix them automatically.

2] Repair Windows Update client using DISM

If the Windows Update troubleshooter could not fix the error, try repairing the Windows Update client using DISM.

DISM is a built-in command line tool used to service or repair a Windows image. To find and repair corrupt or missing system files on your system, run Command Prompt using administrator privileges and type the following command in it:

DISM.exe /Online /Cleanup-image /Restorehealth

The /Restorehealth switch tells the DISM tool to scan your system for corrupt system files and repair them automatically.

Now run the following command in the same Command Prompt window:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

The above command tells the DISM tool to repair the system image using your own repair sources (a running Windows installation, a Windows folder from a network share, etc.) instead of the Windows Update.

After running the above two commands, close the Command Prompt window. Now again try to install the update and see if it works this time.

3] Reset Windows Update Components

If the issue persists, reset Windows Update components to default. Resetting the Windows Update components requires you to run a series of commands in the Command Prompt window. So you have to be careful while running each command. Once the process completes, Windows Update would reset and work again,  and the stuck updates would install on your Windows 11/10 PC.

4] Install Windows Update in Clean Boot

When Windows load normally, several applications and services start running in the background. These applications and services may cause software conflicts when you try to install a Windows update. Clean boot refers to the process of starting Windows with a minimal set of drivers and startup programs to eliminate such software conflicts.

To perform a clean boot, you need to disable all non-Microsoft services and startup items, and then restart your PC. After the restart, your system will enter the clean boot environment. Now try to install the update. If the installation succeeds, you can move ahead and start Windows normally (re-enable the services and startup items and restart the PC).

5] Download Update manually and install it via the Catalog website

If the update fails to install in the clean boot state, download and install it manually via the Microsoft Update catalog.

Note down the KB number associated with the update and search for it on the Microsoft Update catalog home page. Download the required update and install it on your system following the on-screen instructions. Reboot your PC once to finish installing the update.

I hope this helps.
