Installing a Windows 10 upgrade is definitely not an easy task since the process is not always smooth sailing and you could encounter some errors when doing so. This isn’t unusual since there are various software configurations and hardware configurations as well as services it depends on in order to properly work. So if any of them malfunctions or becomes corrupted, it will affect the process which will result in errors like the error code 0x80300002. When you encounter this kind of Windows Update error, you will see the following error message on your screen:

“We couldn’t install Windows in the location you choose. Please check your media drive. Here’s more info about what happened: 0x80300002”

You can encounter this kind of error if there is corruption in the partition table of the drive where the installation is in progress. In addition, corruption on the Media device could also cause this problem. So if you encounter this error when running Windows Setup, read on as this post will guide you in fixing it. There are several ways to resolve this issue. The first thing you can do is to verify the compatibility between the BIOS and the installation media. You could also try recreating all the partitions as well as recreating the bootable USB drive. For more detailed information, follow the given options below.

Option 1 – Check if the BIOS is compatible with the installation media

The first thing you can do to fix the error is to check if there are any compatibility issues between the BIOS and the installation media you’re using. This is actually one of the most likely reasons why you’re getting the error since this is a complicated point for the Windows installation process. If the installation media is based on GPT, then your BIOS must be based on UEFI. So if you have your bootable media with the MBR partitioning, you need to set your BIOS to Legacy.

• 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 “Legacy” option. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to Legacy and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Try recreating a new bootable 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.
• Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
• After that, you should see a new black and white window that would say, “DISKPART>”.
• Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
• Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
• Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
• Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
• A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
• Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick

Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.

• After that, type in this command and tap Enter after – active
• Finally, type this command and hit Enter to exit the utility – exit
• After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.

Microsoft has been bringing new lock-screen features with every iterative feature release of Windows 10 in order to improve user experience. However, Windows 10 users have different opinions regarding it. Some users are pleased with it while some users simply do not like it. So if you are one of the users who seem to not approve of this feature, read on as this post will be about enabling or disabling the Console Mode sign-in feature in Windows 10. Before you proceed, take note that you will not be able to use your mouse pointer in this Consol Mode login screen and you can only use your keyboard to navigate around various options. You might also want to create a System Restore point just in case. To enable or disable the Console Mode sign-in in your Windows 10 computer, refer to the given steps below. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: Then type in “Regedit” in the field and tap Enter to open the Registry Editor. Step 3: Next, navigate to the following registry path:

ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAuthenticationLogonUITestHooks

Step 4: From there, look for a DWORD named “ConsoleMode”. If you don’t see this DWORD, you can just create a new DWORD and name it as “ConsoleMode” and make sure that its base is set to Hexadecimal. Step 5: After that, double click on ConsoleMode and change its value to “0” to disable it and “1” to enable it. Step 6: Now restart your computer to apply the changes made. Like pointed out, you can only use your keyboard when you’re in the Console Mode login window or screen. You can just use the ESC button to go back to the menu while you can utilize the arrow keys so you can go through the options that are mostly vertically arranged and the Enter key to select an option. In the Console Mode, sign-in using the Passwords and PINs worked efficiently.

If you are typing inside the Search bar, Cortana, Taskbar, Windows 10 apps, etc., and then everything seems invisible then read on as this post will guide you in fixing this issue. At first, you might think that something is wrong with your keyboard but it really has nothing to do with it. The problem actually lies with the apps from Microsoft Store. Thus, if you can’t type anything in any of the apps from Microsoft Store in Windows 10, refer to the options given below to fix them.

Option 1 – Ensure that ctfmon.exe is running

Ctfmon.exe is a Microsoft process in Windows 10 that controls the Alternative User Input as well as the Office Language bar. In other words, it enables end-users to control the computer using on-screen keyboard inputs, speech, and even pen for various languages. It would be better if you launch the program once by going to the C:/Windows/system32 folder. Doing so will ensure that whatever API is needed for the keyboard typing to work properly again. You also have to make sure that its startup status is not disabled. In addition, you can also try the following steps, alternatively.

• Open the Task Scheduler.
• Then go to Microsoft > Windows > TextServicesFramework.
• And on the MsCtfMonitor, right-click and enable the task.
• Now restart your computer.

This will ensure that all the text boxes will start to work again. And if the task MsCtfMonitor is missing from the list of tasks, you can import it with the XML file from basics.net. Then download and create a task to run it each time you log in to your PC.

Option 2 – Use the Windows Store Apps Troubleshooter

You might also try running the Windows Store Apps Troubleshooter as it can help in resolving issues with the Windows Store apps. This built-in tool can resolve most of the app-related problems. To use it, go to Settings > Update & Security > Troubleshooting > Windows Store Apps and from there, click the start the troubleshooter button. The Windows Store Apps Troubleshooter will scan the computer for any issues with the Windows store apps and will automatically fix them if it finds any.

Option 3 – Re-register all the Windows 10 UWP apps using PowerShell

• First, make sure to close all the running applications on your computer.
• Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
• After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
  • reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
  • get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
  • $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
  • get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to 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” which could help in fixing the problem.

• 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
  • 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 5 – 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. 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.

• Restart your PC.

You have the option to choose to configure the Network to Private or Public when you set it on Windows 10 PC. On the other hand, if the option to change the Network from Public to Private goes missing in Windows Settings then this post will surely help. You can find this setting under Settings > Network and Internet > Ethernet and appears when you click on it. If you are not able to see the option to change the network profile, then you either can’t open the settings, or the option to change it has been disabled. To resolve this issue, you can either use the Registry Editor or Windows PowerShell. Refer to the options given below for more details.

Option 1 – Change the Network Profile via Registry Editor

Changing the Network Profile can be done using the Registry Editor. But before you proceed, make sure that you create a System Restore Point first just in case. Refer to the steps below to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetworkListProfiles
• Now expand the Profiles key folder located in the left pane to see one or more folders.
• Next, expand each one of these folders and look for the “Description” sub-key which should match the name of your network.
• After you find the Description sub-key, look for another sub-key named “Category” and double click on it to open it.
• Now change its value from “0” to “1” to change the Network Profile from Public to Private.

Option 2 – Change the Network Profile via Windows PowerShell

Aside from the Windows Registry, you can also use Windows PowerShell in changing the Network Profile from Public to Private and so on. Take note that you have to use PowerShell with admin privileges. Just refer to the steps below to do so.

• Tap the Win + X keys and then select the “PowerShell (Admin)” option.
• Next, click on Yes if the User Account Control prompt appears.
• After that, execute the commands listed below. Hit Enter right after you key in each one of them.
  • Get-NetConnectionProfile
  • Set-NetConnectionProfile -InterfaceIndex <index number> -NetworkCategory Private

Note: Since every Network Profile has an index number, you can check the label “Name” to identify the network that you want to change.

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error 0x8007001E. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 5 – Clear the contents in the Software distribution and Catroot2 folders

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

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

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

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

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 6 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses? See our guide: How to Work Remotely and Securely

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

As of the time of writing this article you no longer need or are required to have a password if you plan to log in to your Microsoft account. Microsoft explored various options for account security and came to the conclusion that passwords are obsolete. Microsoft is letting you access your account through the Microsoft Authenticator app, Windows Hello, a security key, SMS verification, or email verification code. All of these methods are way better in terms of security than passwords.

How to turn these features on?

To get rid of your Microsoft password, the process is simple. You simply need to go to your Microsoft account, click “advanced security options,” then “enable passwordless accounts” under the Additional security section.

Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c. 

Solution

Error Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

• Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• When there are mismatched system files installed or system upgrading process failed or still incomplete.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.

• There are corrupted, outdated, or incorrectly configured device drivers.

• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.

• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.

Further Information and Manual Repair

In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.

Method One: Convert the Drive or Partition from NTFS to GPT

In order to fix Error code 0xc000021a in Windows 10, you might need to convert the partition or drive from NTFS to GPT. See below for the procedure: 1. Shut down your device then put in the Windows installation USB key or DVD. 2. Boot your device to the USB key or DVD in UEFI mode. 3. Inside the Windows Setup, open a Command Prompt window by pressing Shift + F10. 4. Type diskpart in the Command Prompt window to open the diskpart tool. 5. Type list disk to identify which drive to reformat. 6. Select which drive to reformat by typing select disk in the command prompt. Afterward, type clean then hit Enter. Once done, type convert gpt to be able to convert the drive from NTFS to GPT. Finally, type exit and press Enter. You can now close the Command Prompt window. 7. Once the partition or drive is converted from NTFS to GPT, the user can now continue the Windows Setup installation. NOTE: Select Custom in choosing which installation type to use. The drive will then appear as a single area of unallocated space. Choose that unallocated space then select Next. At this point, Windows will now begin the installation.

Method Two: Fix System File Errors

There are times when system files get corrupted or damaged which will result in system failure. If this is the case, you can use a Windows free tool to repair corrupted or damaged system files. 1. Right-click on the Start button then selects Command Prompt (Admin) from the list to open a Command Prompt window. 2. Once the Command Prompt appears, type sfc /scannow then hit Enter. Wait until the process completes. If the process is completed and it doesn’t report any error or issues that remain unsolved, you might want to employ the next method.

Method Three: Reset Windows 10

Resetting Windows will delete all software and user accounts installed in the operating system and will reinstall a fresh Windows. 1. Boot your device using a Windows installation USB key or DVD. Select Repair your computer to locate the Troubleshoot option. Afterward, choose Reset this PC. NOTE: If the device is able to boot the system, you can reset Windows without using a Windows installation USB key or DVD. You just have to boot the device then navigate to Settings in the Start button. Choose Update & Recovery then select Recovery found on the left pane. Choose Reset this PC option then select Go back to an earlier build and Advanced startup. Select Get Started button found in the Reset this PC tab. 2. Depending on your device’s condition, you can either select Keep my files or Remove everything. Both options will remove all applications installed in the device and will revert to default settings. 3. Choose either Just remove my files or Remove files and clean the drive depending on the situation. If you choose the Remove files and clean the drive option, the procedure will take longer as it will erase all the files permanently. In this case, deleted files cannot be recovered. However, if you don’t want to remove files permanently, select Just remove my files. 4. Once you’ve decided how to reset your system, click on Next once the Warning screen appears. Afterward, choose Reset once prompted. When the process completed, click on Continue.

Method Four: Download an Automated Tool

Can’t seem to put up with the long and technical manual repair process? You can still fix this error by downloading and installing a powerful automated tool that will surely get the job done in a jiffy!

When your computer boots up or when it just woke up from sleep but it suddenly encounters a Blue Screen of Death error, saying, “HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C”, then read on as this post will give you some fixes that might help in resolving the problem. You will see the following error message on your computer’s screen when this error pops up:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. If you’d like to know more, you can search online later for this error: HAL_INITIALIZATION_FAILED HAL INITIALIZATION FAILED 0x0000005C”

This kind of Blue Screen error indicates that there is a hardware or device driver problem in your PC. Aside from that, it also signifies that the initialization of the Hardware Abstraction Layer or HAL has failed. This happens only during the relatively short period that the Windows operating system is being initialized, specifically during phase 4 of Windows startup. What’s worse about this kind of Stop error is that it does not just go away after a computer reboot. You may have to boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options, follow the fixes prepared below.

Option 1 – Run CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you resolve the HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then restart your computer.

Option 2 – Run the DISM tool

If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the HAL INITIALIZATION FAILED error as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• Next, type in this command: DISM /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 – Update the Device drivers

• Tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 4 – Try removing any external hardware

You might also want to remove any connected devices and external hardware in your computer as it might help in fixing the BSOD error.

Option 5 – 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 UNEXPECTED STORE EXCEPTION 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.

Option 6 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 7 – Perform a Clean Boot

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the HAL INITIALIZATION FAILED error. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.
