The error 0x800f080A appears when Windows users attempt to install cumulative, feature updates, or optional updates directly from the Windows Update pane. This problem is confirmed to occur on both Windows 10 and Windows 11.

Картинка с сайта: appuals.com

Although this problem is most commonly caused by a local inconsistency affecting the WU component, there are several scenarios where the problem can actually be traced back to some kind of system file corruption affecting Windows Updates or an associated system dependency.

If you’re just starting to troubleshoot this issue, start by leveraging the built-in repair tools to see if you can fix the issue – Windows Update Troubleshooter, SFC (System File Checker), DISM (Deployment Image Servicing & Management).

However, this problem can also be related to some kind of 3rd party interference. As you’ll find out below, there’s a sizable list of 3rd party programs that are confirmed to interfere with the WU component in different capacities.

Another possibility is corrupted temporary data affecting a WU component or dependency – In this case, resetting the WU component or refreshing every Windows file are two reliable ways of fixing the 0x800f080A error.

Below you’ll find a collection of confirmed methods that other affected users have successfully used to troubleshoot this issue.

1. Restart & Reinitiate the installation

Before you start following any of the other potential fixes featured in this article, the first thing you should do is reboot your system and retry the installation of the failing update after the next startup.

A lot of affected users that started to experience this issue immediately after a feature or cumulative update failed to install have confirmed that the installation was completed successfully after the restart.

Note: There’s no official confirmation on why this is effective, but the Windows community suspects that certain WU updates need to be installed right after a successful boot when there aren’t any potentially conflicting 3rd party services that could influence the installation.

Картинка с сайта: appuals.com

If you haven’t tried this already, initiate a system restart and re-try the installation of the failing update as soon as the next startup is complete.

2. Run the Windows Update Troubleshooter

If you’re getting the 0x800f080a problem because of a typical WU discrepancy, running the Windows Update Troubleshooter and implementing the recommended fixing method should help. Most of the time, you don’t even have to do anything since most of the recommended fixes will be automated and require minimal intervention from your side.

Note: The Windows Update Troubleshooter includes a set of automatic repair options that may be used to remedy the most common causes of a failing Windows update.

If Windows Update Troubleshooter is able to pinpoint the source of the problem, follow the on-screen instructions to implement the recommended remedy.

Follow these steps to run the Windows Update Troubleshooter and apply the recommended fix:

1. Open the Run dialog box by pressing the Windows key + R.
2. Enter the Control Panel interface by typing “control” and pressing the Enter key.
   

   Картинка с сайта: appuals.com

3. When asked by User Account Control, click “Yes” to allow administrator rights.
4. Use the Control Panel’s search feature and search for “troubleshooting” (Type in the bar located on the top-right corner of the screen).
5. Select Troubleshooting from the list of search results.
   

   Картинка с сайта: appuals.com

6. Next, you’ll see a list of troubleshooters. Scroll down and Run the Windows Update troubleshooter.
   

   Картинка с сайта: appuals.com

   Note: Unless you’re using Windows 11, this screen will be different as the Troubleshooters are still part of the classic Control Panel menu.

7. When the Windows Update Troubleshooter prompts you, click Next and wait for the initial scan to finish.
8. If you identify a suitable solution, click Apply this Fix to put it into action in the present scenario.
   

   Картинка с сайта: appuals.com

9. After the fix has been enforced, reboot your PC and see if the problem is now fixed by attempting to install the pending update once again.

3. Install KB5000808 update manually

If you’re looking for a quick fix that will allow you to install the failing update without necessarily finding & fixing the root cause of the issue, utilizing the Windows Update Catalog is the easiest and quickest way of circumventing the 0x800f080a error.

Important: Going this route will not address the root cause of this issue. Even if you are able to overcome the error and apply the faulty update, this will not fix the underlying source of the problem.

Even if you manage to ‘sideload’ the failing update via the Windows Update Catalog, there’s a chance the problem will return with the next pending update from Microsoft.

Our recommendation is to continue troubleshooting with the other ways below even if this method allows you to install the failing update.

Update: A lot of users have confirmed that they used this method successfully to install the KB5000808 update after the conventional way of installing the WU update failed.

To get around the 0x800f080a problem by utilizing Windows Update Catalog, follow the instructions below:

1. Open the Microsoft Update Catalog homepage in your web browser.
2. Use the search box in the upper-right corner of the Microsoft Update Catalog page to locate the failed update.
   

   Картинка с сайта: appuals.com

   Note: The updated code may be found in the WU error notice on the Windows Update page.

3. From the list of results, identify the update appropriate to your Windows version.
   

   Картинка с сайта: appuals.com

   Note: Consider the CPU architecture and Windows version while seeking for a relevant update, after assessing the data.

4. Once you’ve identified the necessary update, click the Download button and wait for it to finish downloading.
5. Once the download is finished, double-click the executable file from the Downloads folder.
6. Complete the sideloading of the next Windows update by following the on-screen instructions.
7. Now that the update has been installed, restart your computer and check to see whether the 0x800f080a has vanished from the Windows update screen.

4. Perform SFC and DISM scans

The 0x800f080a Windows Update issue might potentially be caused by system file corruption affecting a system file.

Fortunately, Windows has a set of tools (SFC & DISM) that allow you to identify common system file corruption and repair the great majority of them without any required intervention on your part.

You may run both of these programs from an elevated Command Prompt window in fast succession to solve the underlying reasons for the 0x800f080a Windows Update error.

Here’s a simple step-by-step approach to conducting System File Checker and Deployment Image Servicing & Management scans:

1. To open the Run dialog box, press the Windows key + R.
2. Next, type “cmd” and press Ctrl + Shift + Enter to open a Command Prompt with elevated permissions.
   

   Картинка с сайта: appuals.com

3. To grant administrator access, click Yes on the User Account Control (UAC) box.
4. Enter the following command at the elevated CMD line and press Enter to run the initial SFC scan:

   sfc /scannow

   Note: The SFC tool has a tendency to stall in the middle of a scan, even if the scan is still running in the background. If you see this behavior during the scan, DO NOT stop it – doing so may result in logical problems on your OS disk. Wait a few minutes, and the utility should unfreeze on its own.

5. Let’s run a DISM scan when the SFC scan is finished. To do so, use the following command:

   Dism /Online /Cleanup-Image /CheckHealth

   Important: DSM uses a subcomponent of Windows Update to download healthy versions of broken system files; hence, an internet connection is required to run this type of scan.

6. Once both types of scans have been performed successfully, restart your computer and install the pending update once again to see if the issue is now fixed.

5. Uninstall potential conflicting programs (if applicable)

Even though Windows Update is supposed to be an isolated OS component that can’t be affected by a 3rd party process or startup items, there are a lot of confirmed cases where 3rd party applications are actually responsible for the 0x800f080a error.

Typically, security programs or system management programs are responsible for interfering with the installation of pending Windows updates.

Here’s a short list of programs that other users have confirmed to cause this issue:

• CCleaner
• Tune Up Utilities
• Win Optimizer
• Advanced System Care
• Argente Utilities
• System Mechanic
• Simplitec
• ReImager
• AVG TuneUp
• Glary Utilities
• Daemon Tools
• Speccy

If you’re currently using any of the programs listed above, follow the instructions below to temporarily uninstall them and see if the failing update now installs without the 0x800f080a error:

1. Press Windows key + R to open up a Run dialog box.
2. Next, type ‘appwiz.cpl’ inside the text box, then press Ctrl + Shift + Enter to open up the Programs and Features menu.
   

   Картинка с сайта: appuals.com

3. At the User Account Control (UAC), click Yes to grant admin access.
4. Once you’re inside the Programs and Features menu, scroll down through the list of installed programs and locate the installation that you suspect might be causing the 0x800f080a error.
5. Right-click on the problematic program, then click on Uninstall from the context menu.
   

   Картинка с сайта: appuals.com

6. Follow the on-screen instructions to complete the uninstallation.
7. Reboot your Windows PC and see if the update is now installing without issues.

6. Refresh every Windows Component

Another reason why you might experience this problem is an inconsistency related to Windows Update or an associated dependency.

Before you move down to other methods that will produce ever-lasting effects on your system, a quick and effective way to make sure that no temporary WU files are causing the 0x800f080a error is to refresh every Windows Update component & download folder with a series of terminal commands (performed from an elevated CMD prompt).

Note: Microsoft released several ‘bad’ updates in the past that ended up creating installation problems with certain builds. The problem with these bad updates is that even if Microsoft addressed the issue quickly, there’s a chance the ‘bad’ update installation files are already physically present in one of the two folders (catroot2 and SoftwareDistribution) that Windows Update is using to store temporary files.

If you haven’t tried this yet, follow the instructions below to refresh every relevant WU component and clear the contents of the two Windows Update folders (Catroot2 & SoftwareDistribution):

1. Begin by pressing the Windows key + R to bring up the Run dialog box.
2. Then, in the text box that just appeared, write “cmd” and hit Ctrl + Shift + Enter to start an elevated Command Prompt terminal window.
   

   Картинка с сайта: appuals.com

3. When you see the UAC (User Account Control) window, click or tap on Yes to grant the necessary access.
4. Once inside the elevated Command Prompt, enter the following CMD commands in the same order as listed below and press Enter after each one to stop any WU-related services:

   net stop wuauserv
   
   net stop cryptSvc
   
   net stop bits
   
   net stop msiserver

   Note: To clarify what you’re actually telling the terminal to do – These instructions will halt the Windows Update Services, MSI Installer, Cryptographic services, and BITS services.

5. After stopping all necessary services, use the following commands to clean and rename the SoftwareDistribution and Catroot2 folders:

   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old 
   ren C:\Windows\System32\catroot2 Catroot2.old

   Note: These folders are in charge of storing updated files used by the WU component. Since you can’t delete them conventionally, renaming these directories will drive your operating system to produce new healthy counterparts. This will happen the next time you initiate the download of a pending Windows update.

6. Now that the directories have been renamed, use the following commands to re-enable the previously deactivated services:

   net start wuauserv
   
   net start cryptSvc
   
   net start bits
   
   net start msiserver

7. Restart your computer and install the pending update once again to force your OS to create new download folders. See if the 0x800f080A is now fixed.

7. Repair install or Clean install

If none of the solutions listed above were successful in resolving the 0x800f080a error while installing certain Windows Updates, you can assume that your problem is caused by an underlying system corruption issue that cannot be resolved without targeting the entire OS installation (with DISM and SFC scans).

If you’ve come this far without a resolution, replacing every Windows file with a healthy equivalent is the only option left. This can be accomplished by either an in-place fix (repair install) or a clean install.

A clean install is a simpler method, but the primary disadvantage is that you won’t be able to save your personal data (applications, games, personal media, etc.) unless you back them up first.

If, on the other hand, you choose a repair install, the process is somewhat more time-consuming, but the key benefit is that you get to preserve all of your personal data, including apps, games, personal media, and even certain user settings.

Several users complained of receiving an update error 0x800f080a when they were trying to install pending updates on their PCs. If you are one such user and don’t know what to do next, read this guide till the end. 

In this post, we have discussed the reasons behind its occurrence, along with six ways that should address this problem. Moreover, the solutions discussed work for both Windows 11 as well as Windows 10. So, you may apply the same workaround irrespective of which version of Windows you are currently using.

What may trigger Update Error 0x800f080a in Windows 11/10? 

If you are facing trouble installing the recent Windows Updates, it might be because of one or a combination of the below issues –

• Internal glitches: Troubleshoot Windows Update and check if the problem is resolved.
• Using a third-party antivirus program
• Corruption inside System files or folders: Try SFC/DISM
• Disabled Windows Update Service
• Corrupted Update Components

To resolve Windows updates failing on an error code 0x800f080a, attempt these solutions sequentially –

• Troubleshoot Windows Update
• Reinstall Wireless Adapter
• Check Windows Update Service
• Run SFC/DISM Scans
• Reset Windows Update Components
• Manually Install pending updates

Let’s explore these solutions in detail –

1] Troubleshoot Windows Update

When you are facing trouble installing Windows updates, the first thing that you should do is run Windows Update Troubleshooter. This is an in-built tool that diagnoses underlying causes and resolves them. Here’s how to run this utility program –

On Windows 11:

• Press Windows & I, and browse to the below location.

System > Troubleshoot > Other troubleshooters

Картинка с сайта: howtoedge.com

• Now, follow the onscreen instructions to complete troubleshooting Windows Update.

Note: This tool will check for the probable issues preventing Windows Update from occurring smoothly. If that comes under its scope, the same gets resolved automatically. Else, this will suggest ways that can resolve this issue on your computer. 

2] Reinstall Wireless Adapter

There is quite a possibility that no problem actually exists on your device, yet the updates are failing to download or install. Though you have to find reasons why it fails to install, a slow network may prevent downloading pending updates.

Launch your default web browser and check if you can surf online. If you are able to browse different topics quite easily over your browser, the problem may lie within your Wireless adapter. Several users confirmed that they were able to resolve the 0x800f080a issue simply by reinstalling the Wireless adapter. Here’s how to update it on Windows 11/10 PC –

• Right-click on the Windows icon and select Device Manager.
• Click “>” left of Network adapters to expand this section.
• Right-click on your WiFi adapter and hit the option – Uninstall device. 
• The chosen driver will no longer appear under “Network adapters”.
• Locate the “Scan for hardware changes” icon under the toolbar and click on it.
• Device Manager will refresh soon afterward and bring back the uninstalled driver. 

Restart your PC and check if the update error 0x800f080a is resolved by now.

Can you update drivers using Device Manager in Windows 11?

With recent changes in Windows 10 21h2 and Windows 11, there is no way you can update the concerned driver. So, you are left only with two options to choose from.

The first one is to download and install optional driver updates on your PC. It is quite easy to perform this task by navigating to the Windows Update and checking for optional updates. The second way is to visit the manufacturer’s official site and check if there are any recent driver updates for Wireless adapters. 

3] Check Windows Update Services

Many a time, Windows Updates might fail because the update services are disabled on your computer. Go and check the current status of Windows Update and enable it back when found disabled. Here’s how to perform this task –

• Press Win + R, type “services.msc“, and hit OK.
• When the Services window comes into the display, scroll down to Windows Update and check its current status.
• If this service is turned off, you can’t install pending updates on your computer.
• Right-click over this service, and choose the option – “Start“.

When its status change from Stopped to Running, you may close the Services window, and restart your PC. Sign back into your device again and see if you can now update your Windows OS.

4] Run SFC/DISM Scans

Third-party antivirus programs are known to interact with the system files/folders and make them corrupt. If you do use any external security app, disable that first, and repair file corruption on your PC. To do so, you may take the help of utility programs like – SFC/DISM. 

To try SFC and DISM scans, do the following –

• Launch Command Prompt as administrator.
• On the elevated console, type the following, and press Enter –

sfc /scannow

• Wait for 15-20 minutes while the file corruption is being taken care of by SFC.
• Once this is over, run DISM on the same prompt. All you require is to run this code next –

DISM /Online /Cleanup-Image /RestoreHealth

Картинка с сайта: howtoedge.com

• Just like SFC, DISM will also take 15-20 minutes to find and resolve issues under your System Image.

When the repair completes, reboot your PC and check if the update error 0x800f080a resolves. The timing may increase a bit depending on the level of file corruption. 

5] Reset Update Components

If you are still unable to update Windows normally, clear the contents inside the SoftwareDistribution and Catroot2 folders. These two folders store all the information of the updates that you ever perform on your computer. When the stored data exceeds the permissible limit, this may create problems installing new updates.

Purge the contents inside both these folders. Before you begin clearing the stored data, make sure to stop all update-related services. The services that you need to stop are as follows –

• Background Intelligent Transfer Service (BITS)
• Windows Update
• Cryptographic Service 

You may locate the two cache folders at the following location –

• SoftwareDistribution: C:\Windows
• Catroot2: C:\Windows\System32

After clearing the stored cache, restart all the services that you had stopped earlier. Reboot your PC and check if you can now install pending updates on your device.

Tip: Alternatively, you may reset update components as well. 

6] Manually install pending updates

I hope you were able to resolve the update error 0x800f080a by following the above tricks. In case you don’t, this workaround will work. In this, you will need to download the standalone package from the Microsoft Update Catalog that comes along with each security, non-security, or optional update.

• Windows 11 users may follow this tutorial on how to apply updates manually. 
• Here’s how to perform the manual installation of updates on Windows 10.

How do I fix Windows Update Error 0x800706be?

The update errors on Windows 10 are alike in nature, so you may apply the above workarounds to resolve update error 0x800706be. This error normally occurs because of the disabled Windows Update service, missing/damaged system files, or corrupted Update components. 

Привет! У меня не устанавливается обновление к Windows 10. Показывается сообщение с кодом ошибки 0x800f080a. Конечно, я проверил основные моменты – включены ли службы и есть ли место на диске. С этим проблем нет. Нигде в сети не нашел никакой информации по поводу моей ошибки 0x800f080a. Может кто-то что-то знает? Буду благодарен за помощь.

Have a question in mind why do some of the Windows updates just refuse to install? When you open Windows update history, you might notice it shows that some Windows updates failed to install with different errors such as 0x800f080a or 0x800f0904. If you are experiencing a similar problem Windows Update Won’t Install Updates or Windows 10 update failed to install or it’s stuck downloading you are right on track. In this post, we discuss some of the unique solutions you can apply to make Windows install updates again.

Recently, Microsoft has released Windows update KB5055518 for devices running the latest Windows 10 version 22H2. Installing KB5055518 bumps OS to Windows 10 Build 19045.5608 and focuses on security and non-security fixes. However, several Windows users report Windows 10 update KB5055518 fails to install with different errors 0x800f0922, 0x8000ffff, and 0x800f0826.

Many users describe the problem on Microsoft’s forum

There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:

Why does Windows update fail to install?

Many possible things can cause Windows 10 Updates to fail over and over. A slow internet connection that may fail to download Windows updates from the Microsoft server or a Computer that doesn’t have enough free drive space to complete Windows 10 updates, are common. Again Corrupt update files, due to some reason update service is not started, and third-party software or antivirus conflict also causes Windows update failed to install on your computer.

• Restart your computer and check for updates again, probably help fix the problem.
• You need to free up disk space, disable security software and try to install Windows updates
• Ensure the Internet connection is stable and disconnect VPN (If configured on your computer)
• Running Windows update troubleshooter automatically diagnoses and fixes the related problem on Windows 10.
• Restart Windows update service and Clear Windows update cache helps most users fix such problems.

How to fix Windows update problems?

The first thing we recommend is to reboot your PC, check for and try to install the Windows update again. When you reboot your PC, not only refreshes the operating system but also clears temporary glitches present there that prevent Windows updates download or apply.

Open the command prompt as administrator and run this command SC config trustedinstaller start=auto Now try to install the Windows update again.

Check internet connection

The next thing you need to check is your internet connection. Yes, make sure you have a stable internet connection to download Windows update files from the Microsoft server.

• You can check your internet speed at fast.com or speedtest.net.
• Press Windows key + R, type ping google.com -t, and click ok to check if continuously getting ping replay from the Google server.

If ping replay breaks you need to troubleshoot the internet connection before downloading or installing Windows updates.

In addition, disconnect the VPN if configured on your device and temporarily disable security software before trying to install Windows updates.

Free up some disk space

You need to check and make sure you have enough free space on the system drive to download and apply the latest Windows updates. It’s important, especially if you have SSD drive installed.

• Press the Windows key + E to open Files Explorer, then click on This PC,
• Look at the system drive (usually C)for a  minimum of 10 GB of free space there. If not you need to free up some disk space.

• To free up disk space on your system drive, you can move some download files to an external drive.
