How to Fix ACPI_BIOS_ERROR in Windows 10

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?

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?

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.

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.

This post will guide you in what to do if the DisplayLink in Windows 10 is not working. There are several users who reported that their DisplayLink device has stopped working with the Windows 20 Anniversary or the Creators update all of a sudden. According to users, this issue occurs right after they finish installing a big Windows Update like the Anniversary Update or the Creators Update or right when the DisplayLink driver is updated using Windows Update. DisplayLink is a graphics transport technology that allows users to connect to any computer that supports USB or Wi-Fi. Aside from that, it is also an excellent universal docking solution to any platform which makes it a great solution for enabling multiple displays. Thus, it can be quite annoying when DisplayLink suddenly stops working. There really is no actual error message when it happens. The only telltale sign is that all the devices that use the DisplayLink technology will also stop functioning. There could be tons of reasons why DisplayLink stopped working. It could be due to an incompatible driver, or the DisplayLink driver itself is corrupted or is connected to a USB 2.0 port. In addition, the problem could also be due to the Nvidia Share (ShadowPlay) that conflicts with DisplayLink or that the Universal Serial Bus is broken. To resolve the issue, refer to the following options laid out below.

Option 1 – Run the Hardware and Devices troubleshooter

As you know, Windows comes with a built-in tool that you can use to troubleshoot the problem with DisplayLink. You can find it in Settings > Update & Security > Troubleshoot. For further instructions, follow these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to uninstall DisplayLink and reconnect the docking station

If the Hardware and Device troubleshooter is of no help, you can try uninstalling DisplayLink and reconnecting the docking station. To do so, follow these steps:

• Disconnect the docking station or any other device that uses DisplayLink.
• Tap the Win + R keys to open the Run dialog box.
• Then type “cpl” and hit Enter to open Programs and Features.
• From there, look for DisplayLink, right-click on it and click Uninstall.
• After that, follow the next on-screen instructions that appear on your screen to completely remove DisplayLink from your computer.
• Once you’ve uninstalled DisplayLink, click this link to download and install DisplayLink again.
• Now reconnect the docking station as well as other devices that use DisplayLink and follow the next on-screen instructions to reinstall the required drivers in your computer.
• Restart your computer and then check if DisplayLink is now working fine or not.

Option 3 – Try using a USB 3.0 port

If you are experiencing this issue with DisplayLink with a monitor that you’re trying to connect using DisplayLink, then you have to make sure that you are using a USB 3.0 port. Based on some reports, there are certain monitors that will not work with DisplayLink while connected to a USB 2.0 port since they have insufficient power to run the monitor. Like pointed out earlier, the problem with DisplayLink might have something to do with the Nvidia ShadowPlay. This streaming feature was often reported to crash the DisplayLink monitors which is why you might want to try disabling it for a while to check if it’s really true. Once you’ve disabled Nvidia ShadowPlay, restart your computer and check if your DisplayLink monitor now works.

Option 5 – Reinstall the Universal Serial Bus controller

You can also reinstall the Universal Serial Bus controller to fix DisplayLink since a malfunctioning USB port can sometimes cause issues with DisplayLink.

• Tap the Win + R keys to open the Run dialog box.
• Then type “msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Universal Serial Bus controllers and expand its drop-down menu.
• Next, right-click on every Host Controller and then click on Uninstall Device.
• After uninstalling every entry, restart your computer to force your system to reinstall the drivers you’ve just uninstalled.
• Once your computer has rebooted, wait until the drivers are reinstalled and then try opening DisplayLink again.

Option 5 – Reinstall the Universal Serial Bus controller

You can also try to perform a System Restore as it can also help you fix DisplayLink. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• 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.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

Computer crashes are one of the most annoying things that can happen to users. It often loses your data and work, you must spend extra time if you were in the middle of something and can even break Windows itself. Before we move to the article I just want to say that technically there are no random crashes, there is always a reason why the system hangs up, why you received blue screen, annoying restarts out of nowhere and many more PC crashes. In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:

1. Check switch connectors and power outlets

   Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.

2. Clean your PC and check connectors

   Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.

3. Check the temperature of your CPU

   CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.

4. Check the health of your hard drive

   If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.

5. Run antivirus and firewall

   Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.

6. Keep system clean

   Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.

7. Run memory test

   Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.

8. Do not run applications that are too demanding for your system

   Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.

9. Remove applications you do not use

   This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.

10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.

And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

Minecraft has taken the world by the storm, it was an indie project game and it went mainstream. Dream of every game developer I guess. The dream of every gamer on the other hand is to double click on the game and to play it and not to deal with various issues, especially if they are launch issues. Luckily for all of you gamers, here at errortools we game as well and we are happy to bring you a solution on how to fix Minecraft won't launch issue. So sit back, relax and keep on reading, and hopefully enough you will be gaming again in no time. Follow the guide presented step by step, point by point how it is presented for the quickest way to get back in Minecraft. This guide also presumes that your hardware configurations meet at least the minimum system requirements for running Minecraft.

1. Disable antivirus and firewall

   90% of the time this is the issue why Minecraft is not working, your antivirus or firewall has detected it as a false positive, and access to system internet, etc has been cut. Try disabling it and if everything is working fine add it to the antivirus or the firewall exception list.

2. Run Minecraft as admin

   Minecraft will sometimes refuse to run if it does not has administrator privileges. To make sure this is the case locate the Minecraft executable, right-click on it and choose properties. Go to the compatibility tab and check Run as Administrator box.

3. End Minecraft process

   It came to knowledge that even if Minecraft is not running it can have its processes active in the background. Press CTRL + SHIFT + ESC to open task manager Locate if Minecraft has a process running If you find the Minecraft process right-click on it and choose End Task

4. Run Minecraft in compatibility mode

   If Minecraft still refuses to start try running it in compatibility mode in the previous Windows version Locate Minecraft executable file in its install location Right-click on it and choose properties In the properties, windows go to the compatibility tab Check run this program in compatibility mode for: Select previous version of the operating system, try Windows 8 or Windows 7

5. Update graphic card driver

   The best bet is to go to your GPU manufacturer's website and download the latest version of the driver of your GPU.

6. Remove mods, plugins, texture packs

Mozilla Firefox has introduced a new feature known as Restart with Windows which allows the browser to automatically start when your Windows 10 computer boots. This means that if you leave the Firefox browser opened while shutting down your computer, Firefox will re-open automatically along with the tabs that were opened right before you shut down your computer. Although some users may find this feature convenient, there are others who do not approve at all as it could be a nuisance. So if you’re one of the latter, then read on as this post will show you how you can disable the Restart with Windows feature in the Firefox browser on your Windows 10 computer. Refer to the instructions laid out below to get started.

• Step 1: Open Mozilla Firefox and if it’s opened already, just open a new tab and then type the following text in the address bar:

about:config

• Step 2: After typing the text given above, hit Enter and if a prompt with a warning message pops up, simply click on the “I accept the risk!” button to proceed.
• Step 3: Next, type “Restart” in the search filter which should display the following preference in the window:

“toolkit.winRegisterApplicationRestart”

• Step 4: After that, check for the preference value and then see if it’s set to true or not. If it is set to true, then it means that the Restart with Windows feature is enabled so obviously, to disable it, you need to set its value to false.
• Step 5: Now restart your computer without closing Firefox. After restarting your computer, you should no longer see Firefox starting automatically.

The Restart with Windows feature by default is disabled for most users. On the other hand, Mozilla will have this feature enabled as the default configuration in the coming weeks so it’s best that you now know what to do when that time comes since the newer versions of Mozilla Firefox are already being shipped with the Restart with Windows feature. However, if this post did not help you, then you might want to check if the feature has been added to the Startup folder, and from there, you can disable this startup program using the Task Manager > Startup tab.

A lot of users rely on keyboard shortcuts to carry out tasks on their PCs. One of the most common keyboard shortcuts used is the Ctrl + Shift + Esc which opens the Task Manager. As you can see, the Shift key is not just used to capitalize a text as it can also be used for other functions and plays an essential role in operating a computer. However, if you suddenly find it not working, read on as this post will help you fix the problem. If your Shift key is not working, there are several potential fixes you can check out to fix it. These are the different ways to get rid of the Shift key not working issue on Windows 10:

1. Physically clean the key and keyboard
2. Disable Sticky Keys.
3. Update, Reinstall, or Rollback Keyboard driver.
4. Test the keyboard on another system.
5. Check your connections
6. Run the Hardware troubleshooter
7. Troubleshoot in Clean Boot State.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. Thus, you need to clean your keyboard, especially the Shift key. First, you need to shut down your computer and then unplug the keyboard if you are using a desktop computer and then prepare it for cleaning. After that, use a small cotton ear cleaning tool to get between the creases and clean them. You can dip it slightly in alcohol to make it more efficient in cleaning dust and dirt. And if you can, you have the option to pull apart the keyboard completely and then wipe away all the corrosion from the inside. Once you’re done, put the keyboard back together and then plug it back into your PC. Now turn your PC on and check if the Shift key is now working.

Option 2 – Try to disable the Sticky keys

Another thing you can try is to disable the Stick keys. How? Refer to these steps:

• Tap the Win + I keys to open the Settings app.
• After that, navigate to the Ease of Access section, and here, select Keyboard.
• Next, make sure that the option for Press one key at a time under the Sticky Keys is toggled off.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 7 – Put your PC in a Clean Boot State

You might also want to put your computer in a Clean Boot State to fix the problem with the Shift key. It could be that there is a third-party program that’s preventing the Shift key from functioning. To isolate this possibility, you need to put your computer 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” 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.)
• Now try to connect the external devices and check if the error is now gone.
