Fix Windows Update Error 0x80240020

Athwbx.sys or the Qualcomm Atheros driver file is known to trigger several Blue Screen of Death errors. This occurs when the driver gets corrupted or when the operating system is unable to access or find it. In addition, bad sectors in the hard disk or RAM can also cause BSOD errors. The athwbx.sys file is known to cause the following BSOD errors listed below:

• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (athwbx.sys)
• STOP 0x0000000A: IRQL_NOT_LESS_EQUAL (athwbx.sys)
• STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED (athwbx.sys)
• STOP 0×00000050: PAGE_FAULT_IN_NONPAGED_AREA (athwbx.sys)
• Your PC ran into a problem and needs to restart. You can search online later for this error: athwbx.sys

Before you proceed with the troubleshooting tips given below, you might want to try performing System Restore as it could resolve Blue Screen errors caused by the athwbx.sys file. To run System Restore, follow these steps:

• 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.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first.

Option 1 – Try recreating the athwbx.sys file

The first thing you can try is to recreate the athwbx.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to athwbx.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the athwbx.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time 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.
• 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 install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – 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 with good system files. To run the SFC command, follow the steps given below.

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

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

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

• Restart your computer.

Option 4 – Try to run the CHKDSK utility

Running the CHKDSK utility might also help you resolve the athwbx.sys Blue Screen error. 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.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the Memory Diagnostic Tool

Running the Windows Memory Diagnostic tool in Windows 10 might also help you in fixing the athwbx.sys Blue Screen error. Refer to the steps below on how to run this tool:

• 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 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like athwbx.sys. 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.

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!

I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be. One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed. In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

Diablo 2 resurrected has hit official release and servers seem to be finally taken care of and everything seems to be running smoothly now. The game also received great praise from gamers and attracted old players of the original Diablo 2 game. Speaking of old players of old Diablo 2, they can transfer their old characters into remaster and continue playing them within this new great HD environment. There are some steps and requirements but we are here to help and transferred characters will bring full stash, inventory, and equipped items with them.

Requirements

There are not many requirements for this transfer to occur but they must be respected in order to be successful. The first thing is a minor requirement and somewhat annoying but it needs to be done, firstly fire up Diablo 2 resurrected and create a character, any kind of character with any kind of name, any kind of class. This strange requirement is to actually create a character folder and register it inside D2 resurrected so we can copy old ones there. The second requirement will be that characters that you wish to be transferred must be offline characters. Old battle net online characters cannot be transferred at this moment and probably will not be in the future as well. So for all of you that wish to transfer online characters, bad luck, for the rest of us casuals playing offline single-player mode, we can enjoy our characters.

Process of diablo 2 character trasfer

The process itself of transferring characters when previously mentioned requirements are met is just a simple and copy operation. If you have somewhere backed your characters go into your backup folder and copy files in c:\users\*current user*\saved games\*diablo 2 resurrected folder* If you do not have characters backed up and just have old Diablo 2 installed and playing it, you can go to c:\users\*current user*\saved games\*diablo 2 folder* and just copy all characters files into c:\users\*current user*\saved games\*diablo 2 resurrected folder* Your old characters end with .d2s extension, grab all that you want to transfer, and copy them into D2R. Take note that copied characters cannot be brought back into Diablo 2, once they are copied into Diablo 2 resurrected all further progress on them will be tied to the new game.

Conclusion

That’s it about the transfer process and requirements for it. Fire up the new game version and enjoy.

Symptoms of Blue Screen of Death Errors

Symptoms of a blue screen of death problem are easy to identify: if you have a blue screen error, then your computer will display a blue screen. Also known as the infamous “Blue Screen of Death”, this screen will pop up when something goes horribly wrong with your computer. The screen displays cryptic information about the problem before automatically restarting the system.

Bluescreen Error Causes

This one can be a bit more complex: blue screens are caused by hundreds of different things. In fact, any miscommunication between the hardware and software of the computer can lead to the dreaded Blue Screen of Death, blue screens reference a communication problem between the Windows operating system and the hardware in your PC.

Why do computer blue screens of death errors occur?

Most computer users have experienced a blue screen of death at least once in their life. But have you ever stopped to wonder why they occur? Blue screens of death can occur for a number of different reasons, but the most common reason is that your PC’s hardware failed to properly communicate with its software, resulting in a fatal error. If your video card, processor, hard drive, or any other vital system component encountered a serious communication error with your operating system, then your PC may automatically display the blue screen and shut down for its own safety. Blue screens can also occur as a self-protection mechanism if the PC is overheated.

Further Information and Manual Repair

Where do Windows blue screen errors come from?

Blue screen errors come from many different sources on your computer. However, the majority of blue screen errors seem to come from the Windows Registry, which contains important configuration information about the programs, data, and personal files on your PC. Windows constantly rely on the registry in order to operate normally, but since the registry is incredibly complex (it holds hundreds of thousands of files), errors naturally develop over time. Fortunately, registry errors are fixable. They can be repaired using special registry cleaning software. During a scan, registry cleaning software looks for any registry entries that have errors. Once these entries are found, the software automatically repairs each entry. In many cases, this can permanently repair the blue screen error and prevent blue screens from ever appearing again.

Blue screen Windows 7

Windows 7, despite being Microsoft’s most popular operating system to date, is not immune to blue screen errors. It’s more stable than previous versions of Windows, although many users will inevitably encounter blue screen errors in Windows 7. No matter which version of Windows you’re currently using, the error remains the same: the hardware on your computer has trouble communicating with the software, forcing the system to display the blue error message we all love to hate.

“Blue Screen of Death”

There’s a reason this error message is famously called the “blue screen of death.” Immediately after displaying a blue screen, the Windows computer will ‘die’, which means that it restarts itself. Another reason why the error could be called the blue screen of death is that it is often displayed at the end of a PC’s life cycle. As PCs get older and their hardware starts to fail, blue screen errors become more and more common. In real life, death isn’t reversible. In the computer world, blue screens of death certainly are. With the right software support – like Restoro – even the most novice computer technician can fix their blue screen errors and restore their PC to healthy working conditions.

Update and Shutdown/Restart is not working. As you have probably noticed, every time a new update is released and is downloaded on your Windows 10 computer, the operating system replaces the Restart and Shut down button with “Update and Restart” as well as “Update and Shut down”. This is most likely done so that you won’t miss the update. However, some users noticed that there are times when these buttons still continue to display the same message even if they’ve already performed the required operations such as shutting down or restarting their PCs. Cases like this happen when an update wasn’t installed properly or has failed which is why your computer keeps on prompting you to Update and Shutdown every time. To fix this dilemma, follow the options laid out below.

Option 1 – Try restarting the File Explorer

Restarting the File Explorer can definitely help you fix lots of issues especially when there is some issue with the user interface including this one.

• On the right side of the Taskbar, right-click on any open spot.
• Then click on Task Manager.
• Next, scroll down until you see Windows Explorer.
• After that, right-click on it and select Restart.
• If you are able to kill its process, you have to tap the Win + R keys to open the Run dialog box and type “explorer.exe” in the field, and hit Enter to launch the Windows Explorer.

Option 2 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

• Go to Settings and click on Update and Security.
• From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
• After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

Option 3 – Try setting the Power button to Shut down

In case the first two options didn’t work out, you can try changing what the power button does. To do that, refer to these steps:

• Go to Control Panel > Power Options.
• From there, select the “Choose what the power buttons do” option from the left side.
• Then set the Power button setting the “When I press the power button” option to “Shut down”. After that, it will shut your computer down without installing the updates but obviously, this is only a temporary fix.

Option 4 – Turn off your PC instantly without updating it

• Tap the Win + R keys to open the Run dialog box.
• Type in “shutdown -s -f -t 0” in the field and hit Enter if you really want to turn off your computer without any delay.
• You could also tap the Ctrl + Alt + Del keys and select Shut down from the bottom right menu.

Just like the third option, this is also only a temporary fix.

Option 5 – Try running the Windows Module Installer

The Windows Module Installer is a built-in service in Windows 10 that allows you to fix the stuck Windows Updates in your computer. To use it, follow these steps:

• In the Cortana search box, type in “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Once you’ve opened Command Prompt as admin, type the SC config trustedinstaller start=auto command and tap Enter.
• After the command is executed, you will see the “[SC] ChangeServiceConfig SUCCESS” message displayed on the Command Prompt console.
• Now exit Command Prompt and then check if the buttons are now back to normal.

Option 6 – Put your PC in a Clean Boot State

• 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” checkbox 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 putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

The SMTP error 451 is displayed in the following format:

‘451 Requested action aborted: local error in processing’

This error message indicates that the program cannot send more messages and the server has hit the limit. This is because some mail servers have limits. The sever stops the task of sending and receiving emails when this limit is achieved.

Solution

Error Causes

The causes of error 451 include:

• Server limit reached
• Email rejection due to a remote anti-spam filter
• Request denied by the server
• Viral infection

If the problem still persists after System Restore, then follow the given options below to further troubleshoot the problem.

Option 1 – Try to physically check the hardware of your computer

The first thing you can do is to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card or Graphics Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Option 2 – Run the Video Playback troubleshooter

You might also want to run the Video Playback troubleshooter. To do so, refer to these steps:

• First, open the Windows settings app.
• Then navigate to Update & Security > Troubleshoot.
• From there, scroll down until you see the Video Playback section and click on it.
• After that, you’ll see the Run the troubleshooter button, click on it to run the Video Playback troubleshooter, and follow the next on-screen instructions.

On other hand, you can also run the Hardware and Device troubleshooter if the Video Playback troubleshooter wasn’t able to fix the problem. You can run it from the same page that you run the Video Playback troubleshooter.

Option 3 – Try to rollback, update, or disable the Graphics card drivers

To fix the problem with the HDMI port, you can either roll back, update or disable them depending on your preference in order to resolve the problem.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.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. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters. Note that the rollback option is only available if the update was recent. So if it isn’t there, just click on the Update Driver option.
• From there, Windows will automatically check for problems and update the Graphics card drivers.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Try to reset the Monitor

You could also try resetting the monitor or television using its hardware keys and see if it can resolve the problem. You can just refer to your TV or monitor’s guide for more information on how to reset them.

Option 5 – Try some miscellaneous fixes

Apart from the four given options above, you can also check out some miscellaneous fixes to fix the HDMI connectivity issue and here they are:

• You can try to plug out the HDMI cord/cable from both source and destination and then plug it back in after a couple of minutes.
• You can also check if the HDMI cable you are using is still in working condition.
• You can also try to change the source and the destination of the video and see if either one of them is in a non-workable state.
• Try checking if your settings are how they should be as intended in the “Project my screen” option by tapping the Win + P key combination on your keyboard.

If you suddenly noticed that your Onscreen keyboard in Windows 10 has become completely white or transparent for some reason, then you’ve come to the right place as this post will guide you on what you can do to resolve this kind of issue in your computer.
