As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:

“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”

This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
• After opening the Services Manager, look for the Windows Modules Installer Worker Service.
• Once you found it, check its status and make sure that its Startup type is set to Manual.
• Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.

No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.

We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.

Keep your hardware clean

Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.

Not so far ago we had an article about cleaning your hardware detailing what and how to do it. Here is a link to the article: https://errortools.com/windows/cleaning-your-pc/

Do not keep applications you are not using

Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.

Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.

The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.

Do not use pirated or cracked software

Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.

Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.

Keep your drivers updated

Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.

You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,

Keep software updated

Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.

Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.

Keep Windows updated

Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.

Check the health of your hardware regularly

Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.

If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.

Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.

System image backup error 0x807800A1 & 0x800423F3 appears when you are trying to create a system image backup and the operation fails to do so. If you’re faced with any of these error codes, try our recommended solutions in the order presented below and resolve the issue.

Check Volume Shadow Copy & Software Protection Services

To restart the Volume Shadow Copy Service (VSS) on Windows 10, do the following:

• Press ⊞ Windows + X to bring up the Windows menu.
• Click on command prompt (admin)
• In the command prompt window, type the commands below and hit Enter after each line:

net stop vss net start vss

Once the commands execute successfully, try the system image backup again. The operation should complete successfully. You need to also check if the Software Protection Service is disabled. If it is, then Start it and ensure that it is set to default which is Automatic (Delayed Started).

Create System Image using PowerShell

Command lines are less prone to errors provided the syntax is correct, unlike GUIs that can suffer a glitch every now and then. To create a system image with PowerShell do the following:

1. Open the Windows PowerShell as administrator. To create a System Image in Windows 10 using PowerShell, you will have to run the Wbadmin command.
2. Inside the Powershell window type, then press Enter: wbadmin start backup-backup target: E:-include: C:-quiet-allCritical E: is the target drive where you’re going to save the system image, and C: is the system root drive where Windows is currently installed
3. To extract the created system image, starting over from Windows 10 USB installation media, select advanced startup or open run and type: C: \ Windows \ System32 \ Shutdown.exe / r / o

Use third-party imaging software

If the previous two solutions have not managed to solve the issue there is always an option to use a third-party imaging solution. There are free open source and buying options offering various advantages each. Find out which one works best for you and use it.
