How to Repair Windows 10 Error 0x800F0922

As we near the end of 2022 we look at the current best antivirus software for popular platforms, why they are the best, and why you should get them.

Avira, a great free Antivirus

Avira has been around a long time with its free antivirus version of the larger protection suite. It had its ups and downs but the latest versions are really great. With high-speed scans and low system impact, Avira antivirus is really one of the best free antivirus software currently on the market.

The software itself has also received UI & UX updates making it straightforward and easy to use. The virus scanning engine is the same as in paid version that ranks among the top engines in the world for this type of work. The package also gives you some great browser protection and a good firewall as well, there is really no excuse to skip on this if you want a free solution.

The only thing that we would say is not so great in Avira is reporting some false positives, sometimes even for MS updates, it is rare but it can happen.

Malwarebytes, a powerful Windows antivirus

Malwarebytes Premium is easy to use, simple antivirus solution that shies away from complicated UI, and simply put, it just works. Its scanning engine is well-known and places among the top and best in the world often finding some malware that other can miss.

Another great thing is its integration with Windows itself, it is one of the rare applications that can and will work incredibly well beside your typical Windows protection tools so you can have both of them running at the same time.

Installation and running are really simple and every typical PC user will find it as easy as walking in the park. On the other hand, sadly system impact is a little high and it will have issues running on lower-end systems due to its memory requirements.

Intego MAC Internet Security X9, the best Mac antivirus

Gone are the days when MAC had no virus issues, since MAC rose in popularity among the users, also rose the number of viruses and malware. The system itself has some great protection built it inside but for more security and better control of it, you will need a third-party dedicated solution.

Intego was made by Mac antivirus experts who have been building this kind of software last 25 years. The interface is easy to use and premade presets are really helpful, but the security suite can also be customized to fit your needs and desires.

Since this is only available as a security suite, you are getting a firewall and some other security tools along with your antivirus that will run as a part of it.

The bad side is that scans can sometimes run slow, most of the time they are OK in terms of speed but occasionally they can switch to slower speeds and impact scanning time to some annoying times. Also, there is no webcam protection nor VPN service included where others on this list have them.

Bitdefender mobile security: best Android protection

While protection is not only needed for your gaming or workstation, software suites that are dealing with mobile and tablet security exist. The best of them is the Bitdefender antivirus mobile suite. Low on system resources and low on performance impact with the really great virus detection rate Bitdefender is at the top of suites for your phone.

Consistent high virus detection packed with low battery impact is great but the suite comes with tons of other tools as well like browser security tools, email protection, and real-time link and notification protection.

The application will always scan each file and newly installed application in the background and alert and cut off any found threat. App itself is easy to install and use and most of the time it will do everything in the background for you but offer you customization if you need it.

The package also includes VPN and application lock that will let you protect the critical applications from being accessed as well as an online account scanner. Anti-theft and anti-loss tools, which allow you to find, remotely lock or wipe a stolen or lost device, add yet another layer of protection.

One thing that is missing from this great package is fraudulent call protection. Newer Android phones have this feature inside but it would be nice if Bitdefender had it as well.

Bitdefender, the best antivirus software

Now that we have covered specific cases of each platform, there is one player that has all of them covered and with a quality product, that player is BitDefender and it is great. Personally, this is my protection suite of choice and as I type this it is running in the background.

Bitdefender has it all, low system impact, as a matter of fact, it is one, if not, the lowest performance impact engine on the market currently and that is packed with a great and highly consistent virus & malware detection suite. Along with real-time malware protection, browser security, and anti-spam tools, you also get anti-phishing defenses, ransomware protection, and a strong firewall.

Bitdefender scores are very high in both the zero-day threat and real-world protection tests at AV-Test, an established organization that tests antivirus software. Despite being tested against tens of thousands of well-known and widespread malware threats, the software consistently achieves a 100% blocking rate.

The suite also comes with a restricted free VPN and with parental controls as well. Webcam and microphone protection are also included in the suite and on top of all, it has great pricing plans and constant discounts.

BitDefender is really a great package and it might sound too good, but after years and years of personally using it I have not had single malware or virus issue, the only thing that I would put as a negative is that system is severely slowed down when system scans are performed so be sure to run or schedule them when you are not using your computer. This, of course, can put some people off and I will admit it is a serious drawback but for me, the security of my workstation is more important than leaving the computer for 20 or so minutes in order to perform a full scan of the system.

There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:

• Your PC’s motherboard should support both Legacy and UEFI.
• Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.

Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

• When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
• Make sure to run Command Prompt as admin and then execute this command: exe /convert
• After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
• As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
• Now save the changes made and exit as your computer will restart.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or 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 to good system files that might be the reason why the calculator app is not working properly. 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.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

Many users would probably agree that the Windows Media Player, in most cases, is a lot better than the Groove. Although it is understandable why the Groove Music app was created, it may be time for Microsoft to bring its focus back on Windows Media Player. Even more, so that some users are experiencing an issue where they were not able to play their playlist in the Windows Media Player on their Windows 10 PCs. One particular user claimed that when he removed his music from the C drive and transferred them to the C drive for some reason he didn’t state. Right after he did that, any attempts to play songs in the Windows Media Player just don’t seem to work. Transferring music to a different location shouldn’t cause any issue but for some unknown reason, it did. According to security experts, the reason why the Windows Media Player didn’t play the playlist is that it still believes that the songs are still located in the C drive when they’re really not. So the question here is, how can you get the Windows Media Player to recognize the exact and correct location of the songs? Worry not, for this post will show you how exactly you can do that. Carefully follow each one of the instructions given below to fix the Windows Media Player issue.

Option 1 – Try running the WMP Troubleshooters

In case there are any issues with the Windows Media Player, you can always count on the WMP Troubleshooters to fix the problem for you. These built-in troubleshooters, namely, Windows Media Player Library and Windows Media Player DVD Troubleshooters can help you fix the problem, so run them both and see if you can now play those songs or not.

Option 2 – Try rebuilding the Windows Media Player Database

If the first option didn’t work for you, you might have to rebuild the Windows Media Player database. You can do this by following the steps below.

• Tap the Win + R keys at the same time to open the Run dialog box.
• After that, copy and paste this command in the field: %userprofile%Local SettingsApplication DataMicrosoftMedia Player
• Once you’ve pasted the command, hit Enter then you will see a new File Explorer which is the folder for the Media Player. You will have to delete every item in this folder, except for the folders. Meaning to say, you must only delete the individual contents inside but not the folders.
• Now launch the Windows Media Player again and watch as it rebuilds the music library automatically.

Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]

If you are not able to access the Windows 10 Advanced troubleshooting options within Windows then you’ve come to the right place as this post will guide you on how you can repair or boot the Windows 10 installation without losing data using the bootable installation USB or DVD media. To repair or boot Windows 10 using the installation media, you have to download the Windows ISO, create a bootable USB or DVD drive, boot from the media and select “Repair your computer” and then select Startup Repair under Advanced troubleshooting. To get started, follow the given steps below carefully. Step 1: Frist, download the Windows ISO. Although this is not necessarily needed, it’s still better if you download the Windows ISO first so make sure that you download the same ISO version as installed on your computer. Step 2: Next, create a bootable USB or DVD drive.

• Insert your USB drive into your PC.
• Tap the Win + R keys to open the Run dialog box and type in “cmd” and tap Enter to open the Command Prompt. Alternatively, you can also search for “cmd” in the Cortana search box to open Command Prompt.

• After that, look for the Startup Repair and click on it and then follow the next on-screen instructions. This solution will help you fix issues that do not allow you to boot into your computer.
• On the next screen, you will see the admin account with its name. Click on it and verify using the account password associated with the email.
• After verification, it will start to diagnose your computer and automatically resolve any detected issues related to boot.
• After the issue is fixed, your computer should reboot normally and you should now be able to use it. Note that your personal files are still intact since the process didn’t delete or wipe them out.

There are cases when you want to undo some changes you’ve made to your computer and to do that you have to perform the System Restore task. However, if you encounter an error that states “To use System Restore you must specify which Windows installation to restore”, when doing so, read on as this post will help you fix the problem. This kind of error in System Restore could be due to corrupted files in the system. There are also situations where you are not able to boot up once you encounter this error which could be a big problem. On the other hand, this error might have something to do with corrupted BCD files. Whatever the cause is, here are some potential fixes you have to try.

Option 1 – Try to run System File Checker offline

Like pointed out, since the error might be due to corrupted system files, you can try to run System File Checker offline. How? Refer to these steps:

• You need to go to the Advanced Startup Options and from there select Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the commands given below and tap Enter right after you type each one of them.
  • Cd /
  • Dir

• If you can see the “Users” folder, that is your system’s drive. However, if you can’t see it, you can just change the drive-by assigning “D” as its alphabet volume.
• Then execute this command where “C” is the system drive: sfc /scannow /offbootdir=C: /offwindir=C:Windows
• Now repeat the given steps sequentially.

Option 2 – Try to run DISM tool

You can also run the DISM tool to repair the potentially corrupted system image. First, you have to check the health of the system like checking the integrity of the system files and Windows services. To run DISM, follow the given steps below sequentially.

• Open Command Prompt from the Advanced Startup options.
• After that, execute this command where “C:” is the system volume: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:C:WindowsWinSxS
• If you encounter an error after executing the given command, insert the Windows USB or DVD and then execute this next command where “E:” is the USB or DVD drive: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:esd:E:SourcesInstall.esd:1 /limitaccess
• In some cases, “install.esd” would be “install.wim” and in such case, you have to modify and execute this command: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:wim:E:SourcesInstall.wim /limitaccess

Option 3 – Try to repair corrupted BCD

As mentioned, the error could also be due to corruption in BCD, and to fix it, you can use Bootrec.exe – a built-in command-line tool used to troubleshot issues related to boot up and Windows Startup. Before you run this tool, make sure that you have inserted a bootable USB or DVD into your computer. Once you have that covered, follow these steps:

• You need to go to the Advanced Startup Options.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:
  • Bootrec /Fixmbr
  • Bootrec /FixBoot
• After you execute the commands given above, you should see a confirmation message that says, “The operation completed successfully”.
• Now type the “Bootrec /RebuildBCD” command to rebuild BCD.
• Finally, close Command Prompt and then restart your computer to successfully apply the changes made.

Option 4 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 5 – Try to use the Windows Recovery Environment

If the four options given above didn’t help fix the problem, you could try running Windows Repair and a Windows bootable USB or DVD.

• First, insert the bootable USB or DVD and boot into it, and select the “Repair your computer” option.
• Next, once you see the manufacturer logo on your computer, tap the key to enter into Windows Recovery Environment.
• After that, change the Boot sequence to DVD drive under the UEFI Firmware settings and restart your computer.
• Once your computer has restarted, select the boot order and make changes accordingly as displayed in the BIOS.

Option 6 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “exe /OFFLINE:C:Windows” and hit Enter to execute the command which will start the System Restore process.

Note: You need to replace “C” with the drive where Windows Installation is located.

To function properly and as intended, Windows 10 depends on a number of resources and software components. Even with a simple task as powering the machine, there are already several smaller software components supporting it. However, if any of these resources or components experience issues, it will affect the overall function of the computer. One of the errors reported is the Kernel Power Blue Screen error which is triggered by the Windows Kernel that mostly comes with a Windows Kernel Event ID 41 error. This kind of error can turn off and reboot the computer randomly. Here’s an example of a Bugcheck code entry with the same event:

 “EventData BugcheckCode 159 BugcheckParameter1 0x3 BugcheckParameter2 0xfffffa80029c5060 BugcheckParameter3 0xfffff8000403d518 BugcheckParameter4 0xfffffa800208c010 SleepInProgress false PowerButtonTimestamp 0Converts to 0x9f (0x3, 0xfffffa80029c5060, 0xfffff8000403d518, 0xfffffa800208c010)”

This kind of BSOD error is caused by an issue with the Power Supply components in both the software and hardware parts of your computer. In such cases, if your computer is stuck in a reboot loop, you need to troubleshoot the problem via Safe Mode or in the Advanced Startup options screen.

Option 1 – Try disabling Overclocking

If you have enabled Overclocking, you might have to disable it as some users reported that the Kernel-Power Blue Screen error started to appear right after overclocking. To disable it, follow the steps below.

• Go to the Start Menu and open Settings.
• Next, select Update and Security and go to the Recover tab.
• From there, click on Restart now in Advanced startup. This will restart your computer.
• Once you’re in the Advanced startup, go to Troubleshoot and then select Advanced Options.
• From there, select the UEFU Firmware Settings.
• Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
• From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
• Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
• Start your computer normally and check if the Kernel-Power Blue Screen error is now fixed.

Option 2 – Try to run the Power troubleshooter

The next thing you can do is to run the Power troubleshooter. To do so, follow these steps:

• Go to Settings and navigate to Update & Security > Troubleshoot.
• After that, look for the “Power” option from the given list of built-in troubleshooters and click on it.
• Next, click on the “Run the troubleshooter” button to run the Power troubleshooter.
• Once the troubleshooter is done identifying the problems, follow the next on-screen instructions to resolve the problem.

Note: You could also try to run the Blue Screen troubleshooter to fix the Kernel-Power BSOD error. You can find it under the same page as the Power troubleshooter.

Option 3 – Try to replace the Power Supply Unit

You could also try to consider physically replacing the Power Supply Unit or PSU of your computer and see if that helps or not.

Option 4 – Run the Windows Memory Diagnostic tool

Since this error could be caused by some issues in the memory, you can try running the Windows Memory Diagnostic tool and see if it helps.

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 5 – Try to check physically check your RAM

In this option, you have to check your RAM physically especially if you tend to use multiple physical RAMs on your computer so it can be quite tricky and technical. You have to check first if they are of the same frequency and then verify if the chip is compatible or not. You also have to check if the sockets are attached using some adapter or non-recommended apparatus as it can cause some problems while giving performance hit to your computer.

Option 6 – Try to update the BIOS

Updating the BIOS can help you fix the Kernel-Power BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Note: If updating the BIOS didn’t help, you might want to consider resetting it instead.

Option 7 – Disable Fast Start-up

If you want your computer to boot faster, then you might have enabled Fast Start-up. This feature is ideal for computers that are using a hard disk drive. However, turning on this feature also means that when the computer boots, it might lag some drivers that are loaded when it initially boots up. Thus, it might be the potential cause of the Kernel-Power BSOD error. Thus, you need to disable Fast Start-up. To do that, follow these steps:

• Boot your PC into Safe Mode.
• Then tap the Win + R keys to open the Run dialog box.
• Next, type in “control” to open Control Panel.
• After that, select Hardware and Sound and click on Power Options.
• Select “Choose what the power buttons do” from the left side menu pane and click on Change settings that are currently unavailable.
• Afterward, uncheck the “Turn on fast startup (Recommended)” entry and click on Save Changes.
• Now restart your PC for the changes to take effect and then check if the problem’s fixed afterward.
