Software review series: Visual studio code

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

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

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

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

Option 2 – Perform System Restore

• First, press 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 3 – 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.

If you are visiting a single folder many times during the day it might be beneficial to place its shortcut on the desktop for easy access. But did you know that you can also set a keyboard shortcut for that same folder shortcut making it available simply by clicking desired key combination? In order to make a keyboard shortcut for the desired folder know that it is available only when you have a shortcut of the desired folder, it cannot be done on the folder itself, only on its shortcut. Now folder shortcut does not need to reside on desktop, you can place it anywhere you like, but it must be a shortcut. So the first step is of course to make a shortcut of the folder that you wish to have access via keyboard key combination and place it where you wish. Once you have done this step, right-click on it and choose properties. Inside properties at the top click on the Shortcut tab and then inside Shortcut Key, press the key combination that you wish to associate with this folder. Confirm with OK and start using fast folder access with your desired key combination.

In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
• From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
• Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.
• After that, go to this policy setting: Computer ConfigurationAdministrative TemplatesSystemDevice InstallationDevice Installation Restrictions
• Next, look for the “Prevent installation of removable devices” entry and once you find it, set it as “Enabled”. From this window, you should see the following description of this policy setting:

“This policy setting allows you to prevent Windows from installing removable devices. A device is considered removable when the driver for the device to which it is connected indicates that the device is removable. For example, a Universal Serial Bus (USB) device is reported to be removable by the drivers for the USB hub to which the device is connected. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing removable devices and existing removable devices cannot have their drivers updated. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of removable devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, Windows can install and update device drivers for removable devices as allowed or prevented by other policy settings.”

• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer to save the changes made. This should prevent the installation of any removable devices in your Windows 10 computer.

Internal Error 2324 - What is it?

Internal Error 2324 occurs when you try to upgrade Firefox on your Windows 7 PC. The program fails to install and run successfully. The following error message is displayed:

‘The installer encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2324.’

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.

Recently, a lot of users reported having an issue with Windows Update. According to these users, they got an error message saying, “Windows Update components must be repaired” after they run the Windows Update troubleshooter. So if you are also facing this issue then you’ve come to the right place as this post will guide you in fixing this problem. There are various suggestions you can check out to fix this problem – you can try running the Windows Update troubleshooter again but this time, in a Clean Boot State or you could also run System File Checker or the DISM tool to repair corrupted Windows Update files or reset the Windows Update components. For more information, refer to the given options below.

Option 1 – Run the Windows Update troubleshooter in a Clean Boot State

Repairing the “Windows Update components must be repaired” error is not that complicated. One of the things you can try is to run the Windows Update troubleshooter again but this time, in a Clean Boot State. Refer to the steps below to get started.

• 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”.

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 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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.

Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 4 – Delete the contents in the Software Distribution folder and Catroot2 folder

You can also delete the contents in both the Software Distribution and Catroot2 folders as it could potentially fix the “Windows Update components must be repaired” error.

• 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.

Recently, some users reported not being able to boot up their Windows 10 computers. And during the startup phase, at some time, the bootup sequence is halted with a Recovery error along with an error message saying, “Your PC/Device needs to be repaired” with an error code of 0x0000605. This kind of error message indicates that Windows was not able to verify the digital signature for the file as the signing certificate or it could be that it has expired. To resolve this error, you can follow the potential fixes given below and see if you stumble upon a fix that might work out for you.

Option 1 – Change the Date & Time settings in the BIOS

Some users reported that they were able to fix the error by changing the Date & Time settings in the BIOS. Upon checking, they saw that in their BIOS settings, the date was off several years. As a result, the incorrect date and time settings end up ticking the system into believing that the Windows build has expired long before the actual expiration date. You can check if the error pops up due to the same reasons by accessing the BIOS settings. To do so, you have to tap the Boot key that’s associated with your motherboard manufacturer during the initial startup phase. After that, you can search for a particular boot key online or you can also tap keys like F2, F4, F8, F10, F12, and the Delete key. Once you’re able to access the BIOS settings, locate the Date & time or anything similar, and then check if the date is correct or not. If not, you need to change the date to the actual date and then save the changes made and restart your computer and then check if the issue is now fixed or not. Just remember that if the actual date is past the expiration date of the build you have, you need to change it to an older date. If your Windows 10 PC is able to boot back up, you have to update it to a stable Windows build and then go back to the BIOS settings and change the date to the current one else you will definitely encounter Windows update errors in the future as well as security alerts.

Option 2 – Perform a clean install of a stable Windows 10 build

If every system boot fails accompanied by a BSOD error with error code 0x0000605 “A component of the operating system has expired” and you’ve already followed every instruction on option 1, then it’s most likely that your current Windows build has already expired. Remember that almost all the Windows 10 Insider Preview builds (98xx) are created along with an expiration date and when your computer reaches the expiration date, you won’t be able to boot your computer up. Note that the exact expiration date varies based on the build number. And prior to the expiration date, the operating system will start to display some error warnings telling you that the build will expire and urge you to update the most recent build available. And so once the computer reaches its expiration date, it will begin to reboot every three hours until it no longer boots up which is about 2 weeks approximately after the license has expired. Once the expiration date is up and your computer no longer boots up, you need to perform a clean install and then install the latest Windows 10 build to resolve the issue once and for all.

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.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties.

• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

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

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

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

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

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. 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
