Hive ransomware has been targeting Microsoft exchange servers lately vulnerable to ProxyShell security issues in order to deploy various backdoors. Once the backdoor has been placed various attacks can be performed including but not limited to network reconnaissance, stealing admin accounts, taking valuable data, and even installing and deploying file-encrypting algorithms.

ProxyShell wide abuse

ProxyShell is a set of three vulnerabilities in the Microsoft Exchange Server that allows remote code execution without authentication on vulnerable deployments. The flaw has been used in past by various ransomware like Conti, BlackByte, Babuk, Cuba, and LockFile.

Security vulnerabilities have been reported to be fully patched on May 2021 but how Hive was able to still be successful in exploiting PowerShell and infiltrating into the system there seems to be still some unpatched and open issues.

Hive

Hive has gone a long way since it was first observed in the wild back in June 2021, having a successful start that prompted the FBI to release a dedicated report on its tactics and indicators of compromise.

In October 2021, the Hive gang added Linux and FreeBSD variants, and in December it became one of the most active ransomware operations in attack frequency.

Last month, researchers at Sentinel Labs reported on a new payload-hiding obfuscation method employed by Hive, which indicates active development.

If you encounter an error message saying, “The connection was denied because the user account is not authorized for remote login” when you try to establish a remote connection, read on as this post will help you resolve the problem. This kind of error occurs when the targeted host does not allow you to access that system remotely. Based on the error, you are not authorized to log in remotely which means that you need to obtain the correct permission. There are several potential fixes you can try for this error. You can try to check the Remote Desktop Users group or add users to the Security group or check the Remote Desktop Service itself. Refer to the options provided below for more detailed instructions to fix the “The connection was denied because the user account is not authorized for remote login” error.

Option 1 – Try checking the Remote Desktop Users group

You can encounter this error when the Remote Desktop Users group does not have any permission for your user account that you are using to establish a remote connection. Thus, you need to make sure that your user account is a member of the Remote Desktop Users group. How? Refer to these steps:

• Tap the Win + R keys on your keyboard and then type “cmd” in the field and tap Enter or click OK to open Command Prompt.
• After opening Command Prompt, type the “lusrmgr.msc” command and tap Enter to execute it.
• Alternatively, you can also search for “lusrmgr.msc” in the Start Search and once you’ve opened it, select Users and then double click on your user name to open its Properties.
• From there, switch from the “General” tab to the “Member Of” tab.
• Next, if you can’t see any Remote Desktop Users group under the Administrator, you have to add it. To do that, just click on the Add button.
• After that, on the newly opened window, click on the Advanced and Find Now buttons, respectively.
• And in the Search results box, double click on Remote Desktop Users.
• Now click on the OK button to save the changes made and check if you can now connect to a remote host or not.

Option 2 – Try to add a user to the Security group

You can actually block or allow a user from logging on through the Remote Desktop Services. However, if you do not have the right setting, you won’t be able to use this functionality. Thus, you need to confirm this setting. To do that, follow the steps below.

• In the Start Search, type “secpol.msc” in the field and tap Enter to open the Local Security Policy panel.
• From there, go to User Rights Assignment.
• Next, look for a policy named “Allow log on through Remote Desktop Services” located on your right-hand side and then double click on it to open its Properties.
• If you were not able to find the Remote Desktop Users under Administrator, then you have to add it by simply clicking on the Add User or Group button.
• After that, enter “Remote Desktop Users” in the blank field and click the OK button to save the changes made.
• Now restart your computer and try connecting again to the remote host.

Option 3 – Try checking the Remote Desktop Users group

There is a service that’s supposed to be running and needs to be set up correctly for you to connect to the remote host. And so you need to ensure that this service is up and running. To do so, follow these steps:

• Tap the Win + R keys to launch the Run utility.
• Then type “services.msc” in the field and hit Enter or click OK to open the Services Manager.
• Next, look for the Remote Desktop Services and double click on it to open its Properties.
• After that, go to the “Log On” tab and select the “This account” option and then click on the Browse button.
• On the next screen that appears, look for the Advanced button and click on it and use the Find Now button to search.
• You will see “NETWORK SERVICE”. Double click on it and then save the changes you’ve made to the settings.
• Finally, restart your PC and see if the problem is now fixed.

Still sitting on the fence about upgrading to Windows 11 because you don’t know what to expect? Interestingly, the new edition somehow manages to be both a total revamp and still very similar to its predecessor in many ways. It’s really something to experience for yourself.

We do want to give you a sneak peek, though. So here’s an overview of the biggest changes Windows 11 brings to the table.

What’s different in Windows 11?

1. Visual changes

The first thing anyone will notice after switching to Windows 11 is the striking visual difference. The entire interface is smoother, cleaner and more minimalistic than on Windows 10, even resembling the macOS in some instances.
Perhaps the most obvious change in appearance is the Start menu and Taskbar location, which is now at the bottom center. It’s actually very neat, but if you’re someone who loves familiarity, don’t worry, you can move it back to the left.

Moreover, you’ll notice that the Taskbar includes a Microsoft Teams icon by default (which you can, of course, remove) and that Live Tiles are gone. The News and Interests section has also been removed - or, shall we say, replaced. As opposed to Windows 10, news, weather forecasts and other information are now displayed as widgets.

To add to the cleanliness of the UI, Microsoft also enhanced the ‘Snap Layouts’ feature to help you better organize your windows and maximize screen real estate. It’s similar to app grouping on your smartphone. In Windows 10 this feature is slightly restricted, as it requires some manual resizing and dragging. In Windows 11, you can just hover over the minimize/maximize option on a window, select a layout and throw the windows in there. 

2. New accessibility features

Microsoft has certainly paid attention to accessibility with Windows 10, but Windows 11 takes this to a whole new level.

One of the ways Windows 11 has taken things up a notch is by adding the long-awaited ‘Live Captions’ feature and advanced Narrator options.

Live Captions apply both to media played on your PC as well as your own speech when you’re using the microphone. Keep in mind that, as with almost all kinds of subtitles, you have to be prepared for a potential delay. However, it’s barely noticeable and doesn’t take away from the usefulness of this awesome new feature whatsoever.

As for the Narrator, there are three new voice packs to choose from. Microsoft has tried to put emphasis on a more natural voice than we are used to. So, now you can choose between Aria, Jenny and Guy, who will read pretty much anything off your screen out loud. Aside from this, Microsoft has also expanded the list of braille displays supported by the Narrator feature. 
For users with anxiety or trouble concentrating, a welcomed addition is the Focus app, which is no longer part of the Clock app. It’s now separate and called ‘Focus Sessions’, automatically triggering the Do Not Disturb mode when activated. It blocks all pop-ups and flashes and lets you work in peace until you’re ready to switch it off.

3. Android apps

Android users may rejoice! Windows 11 supports the use of your favorite applications now. 

Microsoft has done this by integrating the Amazon Appstore to the Windows 11 Microsoft Store. From there, you can download your favorite Android apps and use them on your PC in a smartphone-like window.

Unfortunately not too many apps are supported at this time, but Microsoft is working on making the emulation possible for many more. Also, the option is only available in specific regions at this moment - check out if you’re one of the lucky ones.

4. Improved gaming performance

Avid gamers will be happy to hear that Microsoft has put some effort into streamlining Windows 11 for their gaming needs.

To give gamers a supreme visual experience, Windows 11 offers the ‘Auto HDR’ feature. As long as your monitor is HDR-compatible, this feature will automatically adjust the colors, brightness and contrast of games without any input from you. 

Another update is DirectStorage, which we were introduced to in Windows 10 already. In Windows 11, it’s been improved to tweak loading times and overall gaming performance efficiency even better. The predisposition for it to work optimally is that your device has an NVMe SSD. 

The Xbox Game Bar also helps gamers towards a smoother experience. It allows in-game screenshots, viewing processes that are running (similar to the Task Manager), monitoring the CPU and GPU performance and frame rate, integrating the Xbox App and more. There’s also a number of widgets you can now use with the Game Bar, for example the Spotify widget.

Another cool addition is the Xbox Game Pass, which unlocks hundreds of games to play on your Xbox App, with new additions coming in every month.

5. Smart App Control

Aside from a sleek new look and better accessibility for all users, Windows 11 also comes with a security power-up. Bear in mind that this feature is only available on clean Windows 11 installs. 

Smart App Control (SAC) is an AI-powered new feature designed to protect your PC from potential threats. It blocks untrustworthy apps and adware and helps detect potentially unwanted apps, maintaining your PC’s performance and keeping your system safe.

It comes with an ‘Evaluation’ mode, which you should definitely select when running SAC for the first time. That way, the app monitors your usage and assesses whether you’re a candidate for SAC. Some users need it to be on all the time, for others it might be too distracting. Evaluation mode will turn SAC on or off based on your usage.

Don’t disable SAC again unless you’re absolutely sure you don’t need it, since reenabling it will require a fresh install. We recommend you don’t turn it off, as it is a neat feature protecting your data and files from malware at all times.

Summary

Have we piqued your interest in trying Microsoft’s latest OS? It’s a pretty exciting new iteration, but we’ll let you find out for yourself. We hope you like it!

In case you don’t know, the Title bar comes with the Maximize, Minimize, as well as the Close button. However, there are instances when you might notice that the Title bar, Maximize, Minimize and Close buttons are missing in the File Explorer. This kind of problem might be due to some glitch in the computer, or it could also be caused by some built-in tool or an installed program in your computer. Moreover, there are also other factors that you have to consider such as corruption in the system files as well as errors in the user profile which is generated on a domain network, and so on. There are several suggestions you can check out to fix the problem. You can try to boot your computer in a Clean Boot State to see if a third-party program is the root cause of the problem. You can also try to run built-in tools like System File Checker and the DISM tool. You could also get the video buffer emptied, reset or reinstall the program, or recreate the User Profile.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as 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.)
• You need 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.

Option 2 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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 and see if the System32 folder still pops up at startup or not.

Option 3 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Upgrade problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to empty the Vide buffer

These kinds of problems could also be due to bad data in the Video Buffer. Thus, you can try to empty the Video buffer to resolve the problem. All you have to do is tap the Shift + Ctrl + Win key + B keys on your keyboard. After that, leave your computer idle for about 10 seconds until you notice it blink once. Now you try using your computer as usual and see if the glitch is now fixed or not.

Option 5 – Try to reset or reinstall the program

Another thing you can do to fix the issue is to reset or reinstall the program where you encounter the problem. Chances are, you are running the application in the Full-screen mode but you can exit it by simply tapping the Esc or F11 key. However, if nothing changed, then consider resetting or reinstalling the program. Just go to the Windows 10 Settings app and navigate to Apps > Apps & Features. From there, look for the entry of the application you’re having problems with and select it and then click on the Advanced options. After that, click on the Reset button under the Reset section.

Option 6 – Try recreating the User Profile

You might also want to try recreating the User Profile on your computer since some errors in the creation of a User Profile can result in problems like this one. Thus, you have to try deleting the User Profile and then recreate it.

If you are trying to install or reinstall a program on your Windows 10 computer but encountered an error instead that says, “Fatal error, Installation fails, Installation ended prematurely because of an error”, then you’ve come to the right place as this post will guide you how you can fix it. This kind of error is most likely caused by some files that may have been left behind by the previous installation of the program. Each time a program is uninstalled, it leaves behind its files and if the uninstallation process wasn’t completed properly, then it would result in errors like the

“Fatal error, Installation fails, Installation ended prematurely because of an error”.

Moreover, this kind of error is a generic one that can also occur with any software reinstallation or installation. And to fix this error, there are several suggestions you must check out. You can try to install or reinstall the program in a Clean Boot State or restart the Windows Installer Service. You could also try to re-register the Windows Installer Service or re-register the VBScript.dll file.

Option 1 – Install or reinstall the program in a Clean Boot State

It is possible that there are some third-party applications in your computer that are preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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 you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 2 – Try to restart the Windows Installer Service

The next thing you can do to fix the problem is to restart the Windows Installer Service. To do this, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Installer service among the list of services shown.
• Once you found it, right-click on it and open its Properties.
• From there, click on the Stop button and then click on the Start button.
• But if it isn’t running, then just click on the Start button.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if unregistering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Try to re-register the vbscript.dll file

You may have to re-register the vbscript.dll file using the regsvr32.exe before you can successfully install the program and fix the error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type regsvr32.exe vbscript.dll in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.

• First, go to the C:/Windows/System32/GroupPolicy/Machine location.
• And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
• Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
• After opening PowerShell, type this command: gpupdate /force
• The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.

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

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer.

In this post, you will be guided on how to import and export the WSL distros in your Windows 10 computer. WSL, also known as Windows Subsystem for Linux, is a compatibility layer needed to run Linux binary executable in Windows 10, as well as the Windows Server 2019. In case you don’t know, when you reinstall or reset Windows 10, all of its configuration data stored with the WSL distros gets deleted. Going back or restoring the configuration can be quite challenging but worry not for Microsoft has already got this covered as you can now import and export the WSL or Windows Subsystem for Linux distros. There are three aspects that you have to deal with when you import or export WSL distros in your Windows 10 computer, such as importing WSL distro, exporting WSL distro, and uninstalling the imported WSL distros. Before you proceed to the instructions provided below, make sure that all your installed distros are updated via Microsoft Store. Once you have this covered, follow the options below.

Option 1 – Import the WSL distro

• Type “command prompt” in the Start Search and from the search results, right-click on Command Prompt and then select the “Run as administrator” option.
• After opening Command Prompt as admin, execute this command: wsl --list –all
• The command you entered will list all the installed WSL distros on your computer. And now it’s time for you to import a WSL distro by executing this command: wsl --import <Name of the distro> <Fill path to save the backup .tar file>

Note: In the given command above, replace “<Name of the distro>” with the name of the distro you want to import and replace “<Fill the path to save the backup .tar file>” with the location where you want to save the .tar file.

Option 2 – Export the WSL distro

• Type “command prompt” in the Start Search and from the search results, right-click on Command Prompt and then select the “Run as administrator” option.
• After opening Command Prompt as admin, execute this command to see the list of all the installed WSL distros in your computer: wsl --list –all
• After that, execute this command to export a WSL distro: wsl --export <Name of the distro> <Fill path to save the backup .tar file>

Option 3 – Uninstall the imported WSL distro

• Open Command Prompt with admin privileges.
• Next, execute this command to view the list of all the installed WSL distros: wsl --list –all
• After that, execute this command to uninstall an imported WSL distro: wsl --unregister <Name of the distro>
• Once it’s done, close Command Prompt and restart your computer.

USB ports, just like any other ports, also comes with a power rating. The default power output of a standard USB port is 0.5 amperes and if you notice, mobile phones charge slowly on USB ports which explains why. There are times when Windows may throw an error or warning that says, “Power surge on the USB port”. This kind of error occurs when a connected device tried to draw more power and the error comes as a part of that notification so when you select it, it will say,

“A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device”.

To easily fix the problem, you can try to disconnect the device and click on Reset and if you click on Close, the port will not work until you unplug it and then restart your computer. On the other hand, if disconnecting the device did not resolve the problem, you can try running the Hardware & USB troubleshooter or use a USB hub. You can also try to reinstall, uninstall or roll back the USB drivers or run the OEM diagnostics. For more information, refer to each one of the potential fixes provided below.

Option 1 – Try to run the Hardware & USB troubleshooter

• 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.

Note: You could also try to run the USB troubleshooter as it could also resolve the problem.

Option 2 – Try to use a USB hub

If you’ve encountered the error on a specific device, then it is possible that the device requires more voltage. To fix this error, you can try to use the same device on another computer and if you still got the same error, you might want to use a USB hub that comes with its power source. USB hubs come with high-speed charging ports that should be able to supply the power needed for the device.

Option 3 – Update, rollback or reinstall the Universal Serial Bus Controller driver

If updating the drivers of the device did not fix the “The device is not ready” error, you can try to update, rollback, or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 4 – Try running OEM Diagnostics if you have any

If the laptop or desktop computer you are using is a branded one, OEMs usually include software to diagnose issues in the computer like the USB port error. So if you have this software, try to run it for diagnosis and use any given suggestions to fix the error.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.
