Fix Windows Update Error 0x80071a91

Windows updates have become a regular occurrence in our digital lives. They are frequent and have become quite necessary. Most of the time they bring us quality content like fixed security, resolved bugs, and even new features but from time to time update itself can be not downloaded properly or it can have some issues when installing. Windows Update Error 0x800F0825 is one of these update errors that will be reported seemingly after applying the update. Altho annoying error it is nothing system breaking and can be easily resolved. Hello and welcome everyone, today we will provide you with solutions on how to resolve error 0x800F0825 when trying to complete a Windows update.

Run Windows troubleshooter

Built-in Windows troubleshooter can help a lot in resolving these issues and we will try it as a first solution because of its simplicity and ease of use.

• Click on START
• Click on settings
• Navigate to Update & Security > Troubleshoot > Additional Troubleshooter > Windows Update
• Click on Run the troubleshooter
• Follow onscreen instructions and let the troubleshooter try to solve the issue

Clear contents of SoftwareDistribution & Catroot2 folders

Altho SoftwareDistribution and Catroot2 folders are essential for the update process it can happen that badly downloaded updates or similar corruption can be stored there and thus producing this error.

• Open file explorer and locate these two folders, go inside and delete content inside them
• Try updating again to see if corruption inside folders was the issue.

Update manually

If the previous two solutions have not produced a result and the error is still present then go to the official Microsoft Update Catalog and download the update manually The catalog is here. Search for updates from the Windows Update Catalog In the Search box, type your search terms. You can carry out a full-text search, using a keyword, KB article, MSRC bulletin, driver manufacturer, driver model, driver version, product, and a classification. Select the appropriate version of Windows. Search or click on Advanced Search if you want to refine your search. A list will be displayed. Select the updates that you want to download. Click Add for each selection to add it to the download basket.

• Download the updates. You may be asked to install an Active-X download control to be able to download files from this site
• Double-click on the downloaded updates to install them

Administrators can download updates from the Microsoft Download Center or the Windows Update Catalog to deploy to multiple computers If you are running Windows Server Update Services (WSUS) 3.0, System Center Essentials (SCE), or System Center Configuration Manager (SCCM) you can import updates directly into these applications. Security updates, critical updates, service packs, update rollups, definition updates, and critical drivers can be configured to synchronize with your server automatically. You can still import these updates into your application by using Microsoft Update Catalog; however, depending on how you configure WSUS, SCE, and SCCM, you may not need to import the updates.

Disable system protection

In some rare cases, antivirus or firewall could interfere with both downloads and execution of certain files. If each previous solution failed disable temporarily your security software and try executing the update again.

If you are trying to open a program or a game but you suddenly see a dialog box with a message stating that the application was unable to start correctly along with the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT then this indicates that the application is not compatible with the architecture of your Windows 10 computer or is missing dependencies. Although error code 0xC000007B can also occur with other various programs, the STATUS_INVALID_IMAGE_FORMAT error code also means that when you try to run an application that’s designed to run on a 64-bit system and hence gets into a termination state. In addition, if you are also pointed to the NTStatus.h file then it means that the error might be caused by some file corruption. Here’s the full context of the error message:

“0xC000007B | STATUS_INVALID_IMAGE_FORMAT | {Bad Image} %hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

When you see this error message, the first thing you can do is to click on OK to close the application and then try installing the media again to see if it fixes the issue. If not, then you can check out the suggestions given below.

Option 1 – Try installing the application with admin privileges

The first thing you can do to fix the error is to restart your Windows 10 computer and then try installing the application again and this time with admin privileges. Just right-click on the application and select the “Run as Administrator” option. And if your account is a regular one, you need to make sure to ask an admin to help you in installing the application by entering the password when you are prompted to do so.

Option 2 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual checks especially if you are getting this issue of abnormal program termination.

1. Install some qualified drivers

A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.

2. Download and install or update DirectX

As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.

3. Install the Microsoft DirectX End-user runtime

The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.

4. Update or install the .NET framework

The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

If your VPN software blocks and disconnects the Internet or Wi-Fi connection as soon as it is connected, read on as this post will give you fixes to resolve the problem. This kind of issue is odd but not unheard of. Many users use VPN for privacy and security but if it causes internet connection problems, you have to pin down the root cause of the problem and fix it in order to continue browsing the internet with privacy and security. Here are some suggestions you need to check out to resolve the issue between your VPN software and network.

Option 1 – Try installing the latest version of the TAP adapter

Since all VPN software uses a TAP adapter which is mostly from OpenVPN, you might want to download and install the TAP adapter driver to resolve the problem.

Option 2 – Run the Network Adapter Troubleshooter

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Configure the client computer to use the default gateway

This kind of connection problem can occur when you configure the VPN connection as the default gateway on the remote network. In such a case, the VPN settings override the default gateway settings (TCP/IP settings). Thus, you have to configure the client computers in order to use the default gateway setting on your local network for internet traffic as well as a static route on the remote network for VPN-based traffic.

Option 4 – Try to use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could help you resolve the internet connection problem caused by your VPN. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Try checking the settings of your VPN software

If your VPN software has a built-in “kill switch” it prevents any internet usage every time there is a problem in connecting with the VPN server which explains why your internet connection is disconnected when your VPN software is connected. In addition, you could also try to change your VPN software’s protocol since all VPNs support multiple protocols. It could be that the protocol your VPN uses is blocked so try changing to another protocol and see if it fixes the problem.

Option 6 – Update the Network Adapter drivers

You might also want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

To reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

And here is the preview of them

Virtual Reality is slowly becoming standard in gaming. More and more affordable headsets are coming out lowering entry prices and making them affordable for all. But in a sea of new VR headsets, it is important to at least purchase a decent one that will perform nicely and hopefully last longer. Therefore in today’s article, we will address some of the best options currently available on the market,

Oculus Quest 2

With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset. In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience. Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware. Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.

Valve Index VR

Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers. The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.

Sony PlayStation VR

The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles). Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.

HP Reverb G2 VR

HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.

HTC Vive Cosmos

HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR. HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite. Sadly one thing that is bringing this headset down is the price.

The new razer modular table looks like something that came out from Star Trek. Project Sophia is a desk but, it is a special kind of desk. It comes with modules that attach themselves underneath the table itself for customization purposes so each user can somewhat create a layout on the table itself as he or she desires. The table itself comes packed with intel CPU and Nvidia GPU but it is said that this component and PC parts will overall be easily upgraded to different ones as users desires. The table itself looks very basic and it comes with a very large OLED screen between two different sizes depending on your table choice. You can choose between 65” or 77” screen sizes and OLED is mounted on the table itself so you cannot move it or adjust the angle of it that I somewhat find annoying but that comes from th4e fact I am used to adjusting my screens, but for this large screen maybe you do not need to adjust its rotation in order to get best viewing angle. Modules themselves will offer some on-the-fly information and quick settings for the PC itself while being modular in a sense they could be mounted in different positions on the table itself providing some customization and order to suit users needs. Modules, for now, are: THX Spatial Surround Sound Controls, system monitoring, programmable hotkey module, Thunderbolt™ Powered eGPU, RAID Controller, Network Performance Module, 15W Wireless Charger, Thunderbolt™ 4 Hub, Media Controls. Of course table, itself will have Razer chroma RGB on its surface and Razer says it will have a total of 13 different modules available on launch for a true level of personalization.

Conclusion

Is this Razer table something that you really need or just another expensive toy? Personally, I would not mind this table at all but I would choose modules for work, not gaming. Having some things like media controls or RAID controllers all the time at your fingertips is a great time saver and productivity asset. Razer also advertises some modules and setup already for streamers, creators, or team members and has some according modules like touch screen digitizer with stylus and similar.

Booting the Windows computer system includes loading it from the various boot devices such as drivers, network as well as USB drives when the computer is turned on. The instant the startup sequence is done loading the operating system the system hardware will be ready to perform some complex operations – in this process, the Boot Log in Windows 10 is a record that maintains the list of success or failure of many pieces of Windows 10 system during the booting process. In other words, the Boot Log is the one that keeps a record of all that has happened while loading from the computer storage system to the memory during the boot process. It is available for several devices like network, hardware devices, and the operating system which assist in detecting issues during the boot process and other issues with regards to troubleshooting. Through Boot Log, you’ll know which drivers were unloaded and loaded from the start of the system during the boot process. You have the option to either disable or enable this feature on your Windows 10 PC. Named as “ntbtlog.txt”, the log file lists all the successfully loaded processes and the unsuccessful ones during the boot process. It is saved to the drive C:Windowsntbtlog.txt. As mentioned, you can enable or disable this feature in two ways – the first one is by using the System Configuration or MSConfig while the second one is using the Command Prompt. In this post, we’ll show you how you can enable or disable Boot Log in Windows 10 either way.

Option 1 – Enable or Disable Boot Log using System Configuration

Enable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and check the checkbox labeled “Boot Log” under the Boot options so that you can enable the Boot Log feature.
• Then click on OK to save the changes made.
• Next, click on the Restart button in the prompt window to get started with the Boot Log process.
• After restarting your PC, go to C:Windowsntbtlog.txt to open the boot log.

Note: As pointed out earlier, the log file contains a list of all the successfully loaded drivers and also the list of drivers that failed to load during the boot process and every time you restart the system, the boot log file will keep on updating and will eventually increase the list of entries. For you to locate the drivers and make your troubleshooting a lot easier, I advised disabling the boot log after troubleshooting. To disable the boot log using System Configuration, refer to the steps below. Disable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and unmark or uncheck the checkbox labeled “Boot Log” under the Boot options so that you can disable the Boot Log feature.
• Then click on OK to save the changes made.

Option 2 – Enable or Disable Boot Log using Command Prompt

Enable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• After opening Command Prompt, type in “bcdedit” and tap Enter.

Note: You have to find the Identifier of the current operating system first to enable the Boot log. You can find it under the Windows Boot Loader section in the “Description” field and in this case, it’s Windows 10. You can also find the operating system identifier under the Windows Boot Loader section next to the field name identifier.

• To check if the boot log entry is disabled or enabled, go check the “Bootlog” field under the Windows Boot Loader. And if it turns out that the “bootlog” entry is enabled, the entry will be “Yes”. Otherwise, the entry will be “No”.
• Next, type in the following command with the operating system identifier to enable the boot log.

bcdedit /set {identifier} bootlog Yes

Note: In the command given above, make sure that you replace the given system identifier with your computer’s system identifier. For instance: In this example, the identifier was replaced with the actual operating system identifier as current.

bcdedit /set {current} bootlog Yes

• Afterward, restart the system to start the Boot log process.
• After the restart, go to C:Windowsntbtlog.txt to open the boot log.

Note: Every time you restart your computer, the boot log file will keep on updating which will increase the size of the log eventually. So if you want seamless and easier troubleshooting, it is advised to disable the Boot log after you troubleshoot. To disable it using the Command Prompt, here’s what you have to do. Disable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• Once the Command Prompt is opened, type in the following command and then tap Enter to disable the boot log feature.

bcdedit/ set {identifier} bootlog No

Note: In the command given above, you need to replace the given system identifier with your computer’s system identifier. For instance: In this example, the {identifier} was replaced with the actual operating system identifier as {current}.

bcdedit /set {current} bootlog No

• Now close the Command Prompt.

What Is Sndvol32.exe Error?

Sndvol32.exe is actually an important part of the Windows operating system. Responsible for managing the sound-card volume and running programs properly, the problem occurs when error messages appear. The user will be unable to listen to music on the system. Usually, Windows XP users encounter the Sndvol32.exe error.

Solution

Error Causes

Sndvol32.exe error can be caused by any one or several of the reasons listed below.

• Accidental deletion of the DLL file from the system
• Damage to the DLL file due to spyware or virus infection
• Improper removal of software
• Unintentional overwriting on the DLL file by a mismatched version
• Obsolete hardware drivers
• Several obsolete/invalid registry entries
• Corrupt registry entries

Regardless of what triggers the Sndvol32.exe error, it is of utmost importance to take immediate measures to fix the problem and to keep it from occurring again.

Further Information and Manual Repair

If you are looking for ways to fix this error manually, the Windows functionality of System Restore will come into play in this particular scenario. In case the error is caused by a damaged or corrupt file, performing System Restore is an ideal choice as it will allow you to not only get a fresh copy of the operating system, it will be possible for you to remove the error at the same time as well. The procedure for performing System Restore is outlined below as follows.

• Click on the Start menu and type ‘System Restore’ in the search box.
• When the icon for ‘System Restore’ appears, click on it.
• Now type ‘Restore’ in the search box that appears on the start menu.
• The window for the System Restore center will now appear.
• Now you have two options. You can either opt for “Recommend Restore” which is the case where the system itself will choose a restore point for you or you can select “Choose a different restore point”. Users are advised to choose the latter option as it is more customizable.
• Users can now select from a list of restore points that have been created before. If you observe closely, you will realize that one of the restore points is prior to the occurrence of the Sndvol32.exe error.
• Click on the restore point. Once you have confirmed your selection, your system will restart and it will roll back to its previously selected restore point.

One recommendation is to perform the system restore in Windows Safe Mode. This is just to ensure that the System Restore is performed smoothly and any potential problems are kept at bay.

Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

• CPU Cores: 8
• GPU Cores: Up to 10
• Unified Memory: Up to 24 GB
