Error Code0x80070426 - What is it?

When Windows evolved into Windows 10, the program known as Windows Security Essentials is no longer. It is now the program known as Windows Defender. When a computer is upgraded from a previous version of Windows up to Windows 10, the Windows Defender takes over and will replace the Security Essentials. In a small percentage of Windows 10 upgrades, something will go wrong and the new program will fail to replace Security Essentials. The result will be that the operating system has both of the programs installed. In this case, Windows Defender will not offer any protection and Security Essentials will not be able to defend either. This error code will also present itself when the Windows Mail App in Windows 10 fail to retrieve and sync email from the user's account.

Common symptoms include:

• There will be an error message that says: “An error has occurred in the program initialization. If this problem does continue, contact your System Admin. Error code 0x80070426.”
• The computer will be left completely vulnerable to spyware and viruses.
• The Windows Mail App will not be able to retrieve mail and will not sync with the PC user's mail.
• The user can be doing anything on their computer and the error code will show up unprompted.
• The computer will lock up, become slow, crash, or even freeze when dealing with error code 0x80070426.
• The programs from an older version of Windows do not replace the newer version from Windows 10.

Solution

Error Causes

Error code 0x80070426 will present itself when a PC user has upgraded their OS from a previous version of Windows to the new Windows 10 version. When this happens, a small portion of users will experience the disconnect between older versions of specific programs, namely the virus protection. When the previous version of the program under a different name is not completely removed and the new virus protection program is installed, the programs will cancel each other out and collectively offer no protection.

This error code may also be found when Windows 10 tries to sync the user's email with the Windows Mail App.

Further Information and Manual Repair

There are a few methods to repair this problem. It should be noted that should anyone feel that the instructions are too complicated, they should contact a Windows repair technician to ensure that the error is fixed properly.

Method One: Uninstall Microsoft Essentials

Hold down the Windows Key and press R. Type in taskmgr into the run dialogue. You should locate the Windows Defender Service (this may show up as Windefend). Right-click on it and then choose Stop.

This will stop the program, but the program will start back up automatically when the computer restarts. While this program is stopped, uninstall Essentials.

To do this: go to Control Panel, Programs, and Features, Uninstall a Program. Alternately, you may hold down the Windows Key and press R, type in appwiz.cpl, click OK, and then locate Microsoft Essentials. Uninstall it, and then restart your computer.

After this is done, go to Settings, Update, and Security. Choose Windows Defender and ensure that Real-time protection is on. Refer back to the Task Manager, Services. Make sure that Defender service is on and running.

Method Two: If the problem occurs in the Windows Mail App

When error code 0x80070426 presents itself in the form of an error with the Mail app, it may be necessary to run an SFC scan.

Right-click on the Start menu or Windows icon, and select Command prompt. The command prompt may be navigated by using shortcut keys Win and X and then select it.

Run the command prompt and then type in sfc /scannow and then press enter. The SFC scan will be run, and be careful not to abort the process before it has finished. This will scan for any files that are lost or corrupt on the PC.

If the scan has found any corrupt files, type in this code and then hit Enter: findstr /c:”[SR]” %windir%LogsCBSCBS.log >”%userprofile%Desktopsfcdetails.txt.

To skip the repair of corrupt or missing files, type in: Dism /Online /Cleanup-Image /RestoreHealth. The details of the scan can be found on the sfcdetails.txt file that will be on the desktop.

Error Code 0x80070008 - What is it

Error Code 0x80070008 generally appears on machines running Windows 10, although it may sometimes also appear on earlier versions of the software, going all the way back to Windows 7, when the error was first introduced.

Common symptoms include:

• Inability to complete the Windows 10 Update process fully
• Machine running slowly
• Messages about a lack of memory on the device in question

If Error Code 0x80070008 has appeared on your computer, there are several things that you can do in order to fix the error and be able to install updates as necessary. Most of these methods are simple enough to use, even for the most inexperienced users, but at least one of the methods may require advanced knowledge or comfort in changing your settings on a deeper level.

If you don’t feel comfortable in your ability to use the steps below to resolve Error Code 0x80070008, get in touch with a qualified technician who is experienced in memory issues and Windows 10 error code resolution to assist you.

Solution

Error Causes

There are three basic causes for Error Code 0x80070008. The first is that your machine may not have enough memory to finish the installation of an update. The second possible cause is that another program may be interfering with your machine’s ability to finish the update installation. Lastly, Error Code 0x80070008 can occur when a user has a lot of language packs, which may interfere with the ability to complete updates.

Further Information and Manual Repair

Because there are three different causes for Error Code 0x80070008, there are also three different methods to attempt to resolve the error. If you believe that the error may be caused by the number of language packs installed on your device, you should attempt method three first. Otherwise, use methods one and two first.

If you are not confident that you can do the steps below on your own to resolve Error Code 0x80070008, get in touch with a certified computer repair technician that is familiar with Windows 10 issues in order to fix the issue.

Here are the top three methods to resolve Error Code 0x80070008 on a machine running Windows 10:

Method One:  Run the Windows Update Troubleshooter

When Error Code 0x80070008 first appears on your computer, one of the first steps that you can take to resolve the issue is to open up the Windows Update module and click on the “Troubleshoot” tool. This will run a scan on the Windows Update tool to attempt to identify the root cause of the problem and to resolve it automatically for you.

If the troubleshooter finds a problem, simply follow the steps on the screen to resolve the error. In some cases, you may want to restart your computer after this process is complete before you attempt to run the Windows Update tool again.

Method Two:  Close All Programs Until Updates are Done

In some cases, a lack of memory on the machine can mean that running other programs while you are attempting to run Windows Update will cause the update process to fail. Closeout all of the programs that are running on the device, including any antivirus software or firewalls, before you run the update process. If this allows the Update process to run through to completion, you can then reactivate all of the programs that were running prior to the update.

Method Three:  Remove Unwanted Language Packs

This method generally applies to users who have an abundance of language packs installed on their machine, usually more than 20 in total, which may interfere with the update process. To remove unwanted language packs, follow these steps:

• Step One: Open the Start Panel and select “Control Panel.”
• Step Two: Find the setting for “Clock, Language, and Region” and choose “Region and Language.”
• Step Three: Select the option for “Keyboards and Languages,” then under the settings for “Display language,” choose “install/uninstall languages” and select “uninstall display languages.”
• Step Four: For any languages that you do not wish to keep, deselect them and choose “Next.” It may require several minutes for the process to complete.
• Step Five: After the unwanted language packs have been removed from your computer, you can attempt to run Windows Update again. You may want to restart your computer first for maximum efficiency.

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.

When we get ourselves a new USB stick, new hard drive, or any storage device not including optical drives they are usually preformatted and ready to be used out of the box. However, reformating them has several benefits and while we are reformatting we can choose in which file system format we want the memory to be formatted. In this article, we will compare and explore 3 typical and standard format options you can get while formating a new media in Windows 10.

FAT32

The oldest one on the list, coming all the way from DOS days. Great for devices that need to be plugged in different operating systems and for USB flash drives. Its advantages are compatibility with all major operating systems and little memory usage comparing to other ones. However, the file system is limited to file sizes of the maximum capacity of 4GB and partitions can not exceed more than 32GB.

NTFS

First introduced in Windows NT this file system offered slower performance than FAT32 and somewhat limited usability but the main advantages were more stability and fewer errors. Its main advantages are support for files larger than 4GB and partitions larger than 32GB along with the ability for on the file encryption, main disadvantage would be limited operating system usage, NTFS can not be used on systems that work on FAT32 like MS-DOS for example or older versions of Windows. The best usage for this file system is in internal hard disk drives and system drives.

exFAT

New kid on the block, well at least from the perspective of the previous 2. exFAT offers unlimited file sizes and unlimited partition sizes but at a price that is even more limiting than NTFS. Some Linux distributions will require a driver to be installed in order to see the exFAT partition. The best use is in storage, in external hard drives. That's it, 3 major file systems, we hope that you have managed to learn something new today, and remember to drop by tomorrow for more articles about advice, tips, tricks, and troubleshooting.

FindYourMaps is a Google Chrome Browser Extension developed by Mindspark. This extension hijacks your home page and new tab page changing them to MyWebSearch.com in order to display ads more efficiently.

While using this extension you will see additional pop-up ads, sponsored content, and unwanted ads (that are sometimes not ever relative to your search query) displayed throughout your browsing sessions, cluttering up the pages and sometimes even going over page parts, making some pages unreadable.

Several anti-virus applications have marked this Extension as a Browser Hijacker due to its data mining behaviors and ad injections and were marked for removal by most of them.

About Browser Hijackers

Browser hijacking is a very common type of internet fraud where your web browser configurations are modified to allow it to do things you never intend. Practically most browser hijackers are made for advertising or marketing purposes. These are typically used to force visitors to a specific website, manipulating web traffic to generate ad revenue. However, it is not that innocent. Your web safety is jeopardized and it is extremely annoying. What’s more, hijackers will make the whole infected system fragile – other harmful malware and viruses would use these opportunities to get into your system very easily.

Indications of browser hijack

There are many symptoms that indicate the browser is highjacked: your home page is reset to some unknown site; you observe new unwanted favorites or bookmarks added, typically directed to ad-filled or porn websites; The default search page of your web browser is modified; you see many toolbars on the browser; you observe numerous ads show up on the browsers or display screen; your browser has instability issues or displays frequent errors; you cannot go to specific sites such as home pages of security software.

How it infects your computer

A browser hijacker could be installed on your PC when you check out an infected website, click an e-mail attachment, or download something from a file-sharing website. They also come from add-on programs, also known as browser helper objects (BHO), web browser plug-ins, or toolbars. A browser hijacker could also come bundled up with some free application which you inadvertently download and install the browser hijack, compromising your PC security. Browser hijackers can record user keystrokes to gather potentially invaluable information leading to privacy concerns, cause instability on computers, drastically disrupt user’s browsing experience, and ultimately slow down the system to a point where it will become unusable.

How to fix a browser hijack

The one thing you can try to remove a browser hijacker is to locate the malware inside the “Add or Remove Programs” list of the Windows Control Panel. It may or may not be there. When it is, uninstall it. But, many hijacking codes aren’t very easy to remove manually, as they go much deeper into your operating system. On top of that, manual removal demands you to carry out several time-consuming and tricky procedures that are very hard to carry out for novice computer users. Anti-malware application is incredibly efficient when it comes to picking up and eliminating browser hijackers that standard anti-virus software has overlooked. Safebytes Anti-Malware features a state-of-the-art anti-malware engine to help you avoid browser hijacking in the first place, and clean up any pre-existing problems.

Windows 10 is undeniably one of the great operating systems and the same thing can be said about a lot of computers that are running it. However, there are instances when things don’t go as you expect them to be. One of the many issues you might face when using Windows 10 is the inability to upload any pictures over the web. If you are facing this issue right now, you are not alone for a lot of users have suffered from the same problem at least once. Even though it might seem like a minor problem, some users find it inconvenient especially the ones who often upload pictures online. Worry not though for this post will guide you on what you can do if you aren’t able to upload any images to websites on your Windows 10 computer. To get started in troubleshooting the problem, here are some suggestions that might help:

Option 1 – Try to clear browser cache and try downloading again

There are times when some data in the browser is conflicting with the loading of the website and triggers some problems like not being able to upload pictures to websites. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of odd problem in your browser.

Option 2 – Open your browser in Incognito Mode

The next thing you can do to fix the problem is to try opening the web page in Incognito Mode. When your browser is in this mode, it will work without extensions. This would help in fixing the problem especially if it was caused by some extension or toolbar in your browser. All you have to do is open any web page in Chrome and tap the Ctrl + Shift + N key combination to open a window in Incognito Mode.

Option 3 – Try to disable and get rid of the problematic extension

The next thing you can do after trying the Incognito mode in your browser is to see if a browser extension is the one that’s causing the problem. And if you have installed a lot of browser extensions, then identifying which one is the culprit may take a while but not too long. Once you’ve identified the culprit, you can get rid of that browser extension and see if you can now upload pictures on websites.

Option 4 – Try to reset your browser

You might also want to reset your browser as it could also help in resolving the issue. To reset your browser, here’s what you have to do:

Google Chrome

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Mozilla Firefox

• Open Mozilla Firefox and tap Ctrl + Shift + A to access the Add-ons Manager.
• In the Extensions, menu Remove the unwanted extension.
• Restart the browser and tap keys Alt + T.
• Select Options and then move to the General menu.
• Overwrite the URL in the Home Page section and then restart the browser.

Internet Explorer

• Launch Internet Explorer.
• Next, click the wrench icon for Settings.
• Then click Internet Options.
• After that, go to the Advanced tab.
• From there, click the Reset button. This will reset Internet Explorer’s settings to their default condition.
• Now click OK to save the changes made.
• Restart your computer.

Option 5 – Update your browser or switch to another one

The last option you can try is to update your browser. You can do it by checking for any available updates from its official site and then install it. However, if updating the browser did not help, you might want to consider switching to another browser.

If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /ScanOS
  • bootrec /RebuildBcd

• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

select disk number

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.

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.

If you have encountered the NO_USER_MODE_CONTEXT Blue Screen error when using your computer, read on as this post will walk you through a couple of suggestions you can try to resolve this Stop error. This kind of Blue Screen error can occur when a program is trying to leverage the use of a system driver but fails to do so. Some of the common causes of this BSOD error are incompatible or corrupted drivers, incorrect configuration of entries in the Registry, damaged memory locations, malware infection, and many more. In addition, this Stop error does not often occur and indicates that an attempt to enter user mode with no context was made. If this is the first time you’ve restarted your computer after you’ve installed additional hardware, you have to remove the hardware and then restart your computer once again and then check the Microsoft Hardware Compatibility List to confirm that the hardware and its drivers are compatible with your operating system. If it doesn’t help, you can check out the given suggestions below to fix the NO_USER_MODE_CONTEXT Blue Screen error in Windows 10.

Option 1 – Try to update or rollback your device drivers

The first thing you can try to fix the NO_USER_MODE_CONTEXT Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties. Note that the main drivers that might be the cause behind the NO_USER_MODE_CONTEXT Blue Screen error will be listed under the “ID ATA/ATAPI controllers” section as well as the “Storage controllers” section.
• 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.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try running System File Checker or SFC 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. 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 PC.

Option 3 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the NO_USER_MODE_CONTEXT Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• 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 your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them.

Option 4 – Perform System Restore

• First, tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like NO_USER_MODE_CONTEXT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.
