A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.

If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:

1. Complete Memory Dump
2. Kernel Memory Dump
3. Small Memory Dump (256 KB)
4. Active Memory Dumps

Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

• Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
• After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
• Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
• Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
• And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
  • None – this means that there is no dump file created by Windows
  • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
  • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
  • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
  • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD

Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.

• Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
• Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

• The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
• After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
  • No dump file: wmic RECOVEROS set DebugInfoType = 0
  • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
  • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
  • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
  • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
  • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1

Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.

• Now type in “exit” in the Command Prompt to exit it.
• Restart your PC to apply the changes made successfully.

The euphoria around Windows 11 is not dying and reveal that Android apps will work natively inside Windows 11 has raised many emotions and questions. So, Microsoft has announced that Android apps will run natively inside Windows 11 OS and that they will reside alongside your other installed ones as icons, etc. It is no secret that many users have been using emulation software to run Android apps inside Windows so far, so what is the difference?

It is still emulation

Whatever you would like to believe it is still emulation and Android apps are at the end of the day still Android apps running inside emulated environment. This time we will not need third-party emulation software running inside Windows, we will have third-party emulation services running inside Windows. Intel has teamed up with Microsoft in order to integrate Intel bridge algorithms in order to run Android apps, meaning that yea, pretty much we have emulation services running in order to run the application. The problem with this kind of approach is that well emulation software is running and consuming system resources only when we start it, this kind of service is always running and always consuming resources and for someone who really does not care about Android apps at all, this is just a waste of resources.

Android store

The store is another issue here, instead of the Google play store we will have the Amazon app store integrated inside the new Microsoft store. This means that any kind of for example game progress or login information from Google store cannot be transferred into Windows 11, add to that information that in the Amazon app store there are tons of missing applications like SLACK, TRELLO, BitWarden, etc and we might have a serious question here about the use of this feature.

Android apps that do not use Android services

If you even look past that it is still emulation and that it is available on the Amazon app store there is still concern about applications not using Google services for their running. Many Android apps are relying on Google services like location or optimize their use of on-device resources, handle in-app purchases, etc. that cannot be found on this system. Uber is a prime example that uses Google location service to determine your location and for its mapping data, with that application, is useless. Other like Guardian will even pop up message that says Google play service is required in order to even work.

Android apps without Eero system

Amazon Eero system for enhanced internet access is not even yet available in its own app store which brings us to missing some key players like Bank of America, Chase mobile, Bueller, etc. And across the board, the apps that are present in the Amazon Appstore are often as good as abandoned. Lots of titles are numerous versions behind their up-to-date Play Store counterparts, and plenty of programs you encounter in the Amazon environment clearly haven't been touched in years.

Conclusion

Many new Windows 11 features are quality features that I personally consider good but although this one seems innovative and good I simply cannot stand back it up. Android apps were already inside Windows with emulation software which used google services and was working just fine, this was not needed in my opinion.

Common symptoms include:

• Inability to complete the installation process for updates, programs, and system versions.
• Installations quitting out in the middle of the process, particularly as the files are unpacked.

Several solutions for Error Code 0x8007001 require the user to complete semi-complex tasks. If you aren’t comfortable with the processes necessary to finish the methods below, make sure that you get in touch with a certified professional who is familiar with the Windows operating system to assist you in the resolution of the error code.

Solution

Error Causes

In many cases, Error Code 0x8007001 is caused by an installation disk that is not functioning properly or installation files that have been corrupted or changed. When this is the case, the operating system will not be able to begin actually installing the files and will instead hang up as the files are unpacked from the installation set.

Further Information and Manual Repair

For Error Code 0x8007001 to be repaired properly, the missing or corrupted installation files need to be repaired or the system needs to be able to recognize the files that it is missing. This can require some advanced computing knowledge. If you don’t feel comfortable with the idea of undertaking the methods below on your own, contact a computer repair technician who can assist you in following these steps.

Method One:  Load the Install Files on an Alternative Disk

In some cases, the operating system simply cannot recognize the installation files that are present on the disk in question, whether it is on a hard drive, a set of downloaded files, or files from a flash drive. If this is the case on your particular machine, the simplest way to work around the problem is to load the installation files onto an alternative disk source, whether it be a flash drive, CD, DVD, or secondary hard drive. After these files have been properly loaded onto that alternative disk, attempt to run the installation from the alternative source instead.

If this method is successful, it means that the system may have had trouble recognizing the files involved in the installation from the first source, but that the files themselves were not corrupted or changed.

Make sure that you save the alternative disk source after your installation is complete in case you ever need to do a fresh installation on your machine.

Method Two:  Clean Your Disc and Your Drive

If you are installing files from a DVD or CD, check to make sure that the back of the disc is free from scratches and dust. If there are no visible marks on the disc, you may need to open up your disk drive to see if there is a build-up of dust or debris inside of the drive. If this is the case, simply clean your drive and re-attempt your installation process from the included disk.

Method Three:  Run the Windows Update Troubleshooter and Update Your Programs

If the error code is still appearing on your machine, you can open up your Windows Update tool and run the troubleshooting wizard, which will then scan your machine to see if there are any potential problems that it can fix. Next, run the Update tool itself if there are any updates that need to be performed. Sometimes, this can resolve the error at hand. Make sure to restart your computer after any updates or changes have been made so that you can ensure that they are applied by the operating system appropriately.

Method Four: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

There are times when you see a message in Windows Defender saying, “The Threat Services has stopped, Restart it now” when you try to use it. This kind of error is usually fixed by simply clicking on the Restart now button. However, if the error still appears even after you restart your computer and you see another message that says, “Unexpected error, Sorry, we ran into a problem”, then continue reading as this post will guide you in resolving this issue in Windows Defender. Before you proceed with the given fixes below, you have to create a System Restore point first. This way, you can always undo any changes you’ve made in case something goes wrong.

Option 1 – Make sure that the Windows Defender Services are started

The Windows Defender Advanced Threat Protection service is the one that protects your computer from advanced threats by monitoring and reporting security events that happen on your computer. This is why you have to make sure that this, as well as other required services in Windows Defender, are set to their default values and are started. To do so, follow these steps:

• 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 “services.msc” in the field and hit Enter to open the Services Manager
• After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
  • Windows Defender Advanced Threat Protection Service – Manual
  • Windows Defender Antivirus Network Inspection Service – Manual
  • Windows Defender Antivirus Service – Manual
  • Windows Defender Firewall Service – Automatic
• You can right-click on each one of the listed services and then select Start to start them.
• And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
• Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
• Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try modifying some entries in the Windows Registry

If the first option didn’t work in fixing the problem, you can try to alter some entries in the Windows Registry using the Registry Editor.

• First, tap Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
• From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
• To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
• Afterward, set the value of the newly-created DWORDS to 0.
• Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.
