DisplayLink in Windows 10 is not working

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

Option 2 – Try clearing the browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

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

Regular and gaming headphones have many differences between them and not knowing what they are can lead you to get yourself the wrong one. In this article, our goal is to analyze the differences between them so you can choose the right one for you.

Price

One thing that goes in both worlds is that the cheapest models on both sides are not really worth the purchase since both the quality and longevity will be very low. If we compare high-end models, regular headphones are far far more expensive than gaming ones. Hi-end gaming models can go as far as 400$, perhaps a little more but hi-end audio regular headphones are going even for over 2000$.

If we compare same-price headphones generally regular ones will offer you a little better sound quality but gaming headphones will offer some features such as positional audio that regular ones do not have.

Surround sound and positional audio

One of the main advantages of gaming headsets is positional audio and true surround sound. this technology is built-in so you can hear more clearly where your enemy is coming from that is a big help in competitive games. This is achieved by positioning multiple speakers in various positions and angles inside them. Each speaker has a different sound channel that is mixed with another speaker in order to provide you with a full surround experience.

Regular headphones have typically one or two speakers on both sides aimed at the same angle and can not offer precise surround or positional audio.

Noise cancellation

Both gaming and hi-fi headphones offer some sort of noise cancelation to minimize outside noise but if you really want to focus and have good noise cancelation you will have to look out for headphones with active noise cancelation or ANC.

Microphone quality

Let us say this right at the start, most middle and quality regular audio headphones do not have a microphone at all, and ones that might pack one usually have it at a lower quality than gaming ones. This of course makes perfect sense since regular headphones will focus on audio, and gaming ones will focus on playing games where having a good microphone is essential in order to game properly.

Speaker and sound quality

Speaker quality will reflect directly on the sound quality and fidelity. This is where audio regular headphones have an advantage over gaming ones. Since they do not have many small speakers positioned at various angled and instead have just a few, usually 2 or 1 large one, that one is of much better quality and range for audio than a pack of small ones. If you are searching for clarity and quality of the audio itself, especially if you are listening to some FLAC uncompressed music, then regular HiFi ones are a much better choice.

Longevity and durability

Another area where regular ones have an advantage but that is no surprise since their price goes far up compared to gaming ones. Most of the time everything in hi-end audio headphones is made from quality materials and designed to last a long time and therefore advantage. Most of the time gaming headphones will come in plastic versions whereas higher quality audio ones pack a lot of durable metal in frames and in buds making them much more durable. Of course, we are talking here about proper headphone use, not extreme cases of throwing, etc.

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:
  • Network Virtualization Service
  • Virtual Disk
  • Hyper – V Virtual Machine
  • Hyper – V Host Computer Service
  • Container Manager Services
• After you find the aforementioned services, make sure to check if they are enabled or not and then restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.

In case you don’t know, the Windows Registry contains a System Hive which is a core part of Windows. The Windows operating system store various settings, options, and configurations. And if you encounter a Device Manager Error 49 for a device then it means that the system hive has exceeded its size limit. Worry not for this post will provide you with possible solutions that can help you in fixing error code 49. You will see the following error message when you encounter error code 49:

“Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit), (Code 49)”

There are instances when it may so happen that the device or devices are no longer attached to the computer but they are still listed in the system hive of the registry. For instance, if you were removing hardware and application for years but they weren’t removed from the registry then the size of the system hive keeps on growing until it hits the maximum limit. As you know, making changes in the registry manually, no matter how knowledgeable you are on such things is not sage since the registry is not only important but also complex. In addition, the System Hive is also a permanent part of the Registry associated with a set of files that contain information related to the configuration of the computer on which the OS is installed. To resolve this error, you must remove or uninstall any hardware devices that are no longer in the system. In fact, the Device Manager hides them by default so you need to enable hidden or non-present devices. Follow the instructions given below to set the Devices Manager to display devices that are no longer connected to the computer. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: After that type in “cmd” and hit Enter to open the Command Prompt. Step 3: Type “set devmgr_show_nonpresent_devices=1” in the Command Prompt and hit Enter to enable the hidden devices option. Step 4: After that, exit Command Prompt and tap Win + X + M to open the Devices Manager. Step 5: After opening the Devices Manager, click on View and then select the “Show hidden devices” option. This will show you all the devices that are not connected to the computer but are still mentioned. Step 6: Next, select a non-present device and click Uninstall from the Driver tab. Step 7: After that, repeat what you’ve done on step 5 for any other device that you no longer use. Step 8: Restart your computer. You can check the device Properties dialog box in the Device Manager after you’re done removing all the useless devices, to check if the error is now fixed or not. Moreover, you can also try running the Hardware and Devices Troubleshooter as it can also help resolve hardware-related problems. To use it, refer to the steps below.

• 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.

These kinds of things are very unpleasant experiences for both users and the company itself. User trust lowers significantly in the company and it can greatly increase the chances of users migrating to another platform. This just shows how much a hacker or security breach can produce damage to the business. Sadly we can not offer you guidance or assistance in recovering your stolen data nor can we provide you with removing your data from the hands of the attacker. What we can do is to provide you with information has your data been stolen. Threat actor released the personal information for 533,313,128 Facebook users on a hacking forum, including mobile numbers, name, gender, location, relationship status, occupation, date of birth, and email addresses. This data was originally sold in private sales after being collected in 2019 using a bug in the 'Add Friend' feature on Facebook. Facebook had closed this vulnerability soon after it was discovered, but threat actors continued to circulate the data until it was finally released practically for free. Since then, Troy Hunt has added the leaked data to his Have I Been Pwned data breach notification service to help users determine if a Facebook member's data was exposed in the leak. Go to the site and enter your email address to check and see if your data has been compromised.

Error Code 7 - What is it?

This is a typical system error that occurs during Windows setup. To be precise, this error may pop on your computer screen during the text mode portion of Windows setup. The setup hangs and stops responding and the error message is displayed in either one of the following formats:

From the various report, it is now clear that no one is prone to Ransomware attacks. Cyber-criminals never target any specific field of the user workgroup for this Ransomware attack. But in past few years, it has hugely affected home users, businesses, organizations. We can say, Ransomware victims come in all shapes & sizes. Many business owners think that they will never be attacked by Ransomware crooks because their business is not so big. But that’s not true. A huge proportion of Ransomware attacks happened in small sector businesses because of their weak security resistances.

Some leading negative consequences of Ransomware attacks faced by almost every victim are:

1. Permanent or temporary loss of proprietary or sensitive information.
2. Lots of trouble in performing regular operations.
3. Huge financial losses sustain for restoring up your files and systems.
4. Latent harm to the reputation of an organization.
5. Even making the Ransom payment doesn’t guarantee the safe releasing of your encrypted files.
6. Attackers get the victim’s money along with their banking details.
7. Getting the decrypting files doesn’t mean malware infection has completely been removed.

Ransomware put a tremendous impact on disturbing business operations and in the end, leads to data loss situations.

Here are some huge impacts of Ransomware attacks on business are:

1. Damage or loss of all the crucial information
2. In the Ransomware post-attack period Business disrupts a lot.
3. Destruction of hostage data, file, and system.
4. Business downtime
5. Victimized company’s reputation dropdown
6. Productivity loss

Apart from the ransom, the cost of downtime because of restricted system access will bring major concerns. It’s a fact that due to downtime victims may has to pay a cost of ten thousand dollars daily. As, Ransomware is becoming more and more widespread, so all companies require to brush up on their annual cyber-security goals. Moreover, approach for some appropriate implementations of Ransomware recovery plans and commit sufficient funds in their IT budgets for cyber-security resources. Among the most effective impact of Ransomware, “data encryption” is very hard to deal with. Meanwhile, this victim is completely restricted to access any of their encrypted data. The only way for unlocking these encrypted files is through the decryption key which only belongs to hackers. Many times, the decryption key is given to the organization, after the payment of the ransom. But there are also some cases when data is not handover to the victim, even after the ransom payment. The main risk that generates with “operational impact of Ransomware” is on the businesses. Can you just imagine, what will happen if all of a sudden entire services or processes of your business halt down?

Well, this dreadful Ransomware threat is so impactful that it can:

1. Close down the entire plant
2. Freeze manufacturing control system
3. Make other backlogs

All the damages that occur due to downtime can be a major one and can have so many consequences. A well-organized strategy of backup and recovery will not certainly make the Ransomware attack painless. As this takes an extensive amount of money and time for data restoration.

Apart from that, the decision of recovering your system using the backup moreover depends on three things:

1. First the amount of data loss that is considered acceptable by your business or organization.
2. Up to how extent, the impact of Ransomware has spread
3. How fast the Ransomware attack was spotted.

However, in many cases, data gets so encrypted that you can’t revert back to the restore point. At that time external backup is considered the best option. Among the wide-reaching impact of Ransomware “Data loss” is the most effective one.  As it starts from little disruption and leads to permanent business failure. Sometimes data loss in a Ransomware attack leads to disclosure of all your confidential information which ends up in fines and lawsuits. Attackers always look for backup files and folders after encrypting your system data. So that user can’t retrieve their corrupted file from the backup. Such dreadful activities make this Ransomware threat so profitable and effective. Victims don’t have any choice left either they have to pay the ransom or they have to face their risk of data loss.

The Disk Management tool in Windows 10 is a built-in tool that contains a user interface used to manage disk partitions to administrators of the computer. There are lots of instances when you have to change the size of the hard disk partition or reduce the size and so on. This is where the Disk Management tool comes in. It’s useful as the command line interface can be quite confusing and risky for some users. However, there are cases when this tool stops working. A proof of this the reports submitted recently by some Windows 10 users. Based on the reports, the Disk Management does not load or respond. If you are having the same problem, read on as this post will give you some suggestions on what you can do to resolve the problem.

Option 1 – Try restarting the Disk Management Service

• Tap the Win + R key combination to open the Run dialog box.

• Click on Apply and OK to save the changes made.
• If it hasn’t started yet, you can just click on the Start button to start the Service. The Virtual Disk service provides management services for disk, volumes, file systems as well as storage arrays.
• Now save all the changes you’ve made and restart your computer. Then check if you can now use the Disk Management tool without any problem.

Option 2 – Try using 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 that might be causing some issues with the Disk Management tool. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• 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.

Option 3 – Try using the DISM tool

Aside from the System File Checker, the DISM tool can also help you resolve the issue with the Disk Management tool. It helps in restoring the health of your computer.

• Open the Command Prompt as admin.
• Then 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 4 – Try using Diskpart and Fsutil

If both the System File Checker and DISM tool didn’t work, you can use command-line tools like diskpart and fsutil. These command-line tools are powerful but you need to be careful especially if you’re not that familiar with using them. However, it’s recommended that you have somebody who knows if you’re really inexperienced with this kind of stuff.

If you are running Windows Update on your Windows 10 computer and you suddenly encounter error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure then read on as this post will give you a couple of suggestions to resolve this problem. Note that you can encounter this error not only on Windows Update but also on Microsoft Store apps at times. Follow the options given below to fix error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure error on your Windows 10 PC.

Option 1 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 2 – Check the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the Cryptographic Service. Then right-click on it and select Properties from the context menu.
• After that, check if the service is started by checking the Service status. If it is started, click on the Stop button to stop the service and if it is already stopped, leave it as it is, at least for now.
• Next, make sure that the Startup type menu in the Service’s properties is set to Automatic before you go on.
• Now confirm any dialog boxes that may appear as you set the Startup type and then click on the Start button located in the middle before you exit Properties.

Option 3 – Delete the contents in the Software Distribution folder and Catroot2 folder

• 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 4 – Check the Root Permissions

You might also want to check the permissions on the root of C: and make sure that “BUILTINUsers have read access because if it doesn’t, then no wonder why you’re getting the error code 0x8000FFFF.

Option 5 – Try to use the Media Creation tool

The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Option 6 – Try installing the updates in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. 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” 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” checkbox.
• 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 app again.

Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application in your computer. You need to look for the culprit and uninstall it once you found it.

Option 7 – Run 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 code 0x8000FFFF. 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.

DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application. This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

Option 1 – Run System File Checker scan
