Software review series: QuickLook

BSOD or Blue Screen of Death errors are one of the toughest issues you can encounter in Windows 10 as well as the hardest ones to resolve as they simply shut the system down or restart it abruptly and claims that it isn’t possible to boot Windows again. One of the difficult BSOD errors is the Machine Check Exception BSOD error. The reason why it is hard to fix is that in most cases, it occurs soon after Windows loads which gives users little to no time in resolving it. To make things worse, the system also freezes right before it displays the blue screen error and shuts the system down. Usually, the Machine Check Exception Stop error occurs due to the failure or overstressing of the hardware components. And in the case of almost all Blue Screen of Death errors, the issue usually has something to do with the drivers. So if you frequently see this BSOD error from time to time, now’s the time to act on it by following the solutions given in this post.

Option 1 – Update the Device drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 2 – Try running the Blue Screen Troubleshooter

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

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

Option 3 – Try running the System File Checker

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 the Machine Check Exception BSOD error. To run the SFC command, follow the steps given below.

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

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

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

Option 4 – Run the Startup Repair

In the Blue Screen where the Machine Check Exception error is displayed, tap the F8 key to go to the Startup Settings where you can find Startup Repair and then run it. Note that this is a must-try option especially if you are unable to start your computer and if you can use your computer for a few moments.

Option 5 – Run the DISM tool

There are cases when the Machine Check Exception error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /CheckHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Try resetting the BIOS

If you have made some modifications in the BIOS that might have caused this error, you have to revert those changes to resolve the issue. On the other hand, if you have made a couple of changes and you do not remember which is which, you might have to reset the BIOS.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

If you encounter Windows Update error 0x80092004 while trying to update your Windows 10 computer, then this post is for you. This kind of Windows Update error could be due to many reasons but none of them includes your hardware or installed driver software. Microsoft releases updates that are either not supposed to go out, or you install them when you click on the Check for Update button which can install updates that have not finished testing yet. As a result, you may encounter the Windows Update error 0x80092004 To resolve the Windows Update error 0x80092004, here are some fixes you can try.

Option 1 – Try removing recent updates and packages

When a Windows Update fails, it mostly rolls back and cleans up all its residues. However, there are times when it doesn’t and you can clean that package manually. To remove recent updates and packages, you can go to the Update History and find out what KB updates were installed and once you’ve figured it out, you can execute the DISM tool to remove it manually.

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, execute the “Dism /online /Get-Packages”. This will give you a list of packages that were recently installed.
• Now run the Remove Package program to remove the concerned update and package.

dism.exe /online /remove-package /packagename:Package_for_RollupFix_Wrapper~31bf3856ad364e35~amd64~~16299.248.1.17 /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~16299.125.1.6 /packagename:Package_for_RollupFix_Wrapper~31bf3856ad364e35~amd64~~16299.192.1.9 /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~16299.192.1.9 /norestart

• Now restart your computer and log back in.
• After that, run the following command:

Dism.exe /online /Cleanup-Image /StartComponentCleanup

• Then scan for updates.

Note: Keep in mind that the remove package command is made for AMD 64-bit machines specifically.

Option 2 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• 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.

Option 3 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the “We couldn’t install some updates because the PC was turned off” error. 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.

Option 4 – Try to manually install the Windows Updates

Windows Update Error 0x80092004 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes.

Windows Terminal is a new free Microsoft terminal sort of application. When you open either Power Shell or Command Prompt in Windows they will be opened in different windows, and if you want several of each you will have several windows of each on your screen. Windows Terminal fixes this by opening each of the Instances of Command Prompt and Power Shell as separate tabs inside itself making it much easier to manage multiple instances of named applications. You can also run both Power Shell and Command prompt tabs in the same Windows Terminal. Luckily running command prompt and power shell in different tabs is not the only thing you can do. Windows Terminal lets you choose your own theme, it has emoji support, GPU rendering, split panes, and many more customizable options. Windows 11 will have Terminal as the default command-line environment for opening Power Shell or Command prompt, even Windows Subsystem for Linux (WSL)

Setting Windows Terminal as the default application

If I was successful I have managed to show you that Windows Terminal is something that you should use even if you do not or cannot upgrade to Windows 11. You can use it inside Windows 10 also. First thing is to download and install it. You can get Windows Terminal from the official Microsoft website here: Windows Terminal page After download and installation are completed, open the Terminal app and select the down arrow menu, click Settings. Alternatively, you can use CTRL + + shortcut. Inside Settings by default Default Terminal application would be set to Windows Console Host Click on the Default Terminal application to bring a drop-down menu and choose Windows Terminal from the list. Now by default once opened Windows Terminal will use Power Shell as the default profile, however, you can change this by clicking on the drop-down for the default profile where you can choose between Command Prompt, Power Shell, Windows Power Shell, or Azure Cloud Shell. Pick one that you prefer, click on Save and it will be opened as default on the next run.

The Local Security Authority Subsystem Service or LSASS.exe is a process in the Windows operating system that is valuable as it enforces the security policy on the computer. Every time you log in to the Windows Server, the LSASS.exe is the one that handles the password changes and creates the access tokens while updating the security log. However, it is also frequently targeted by malware and is often imitated. The original location of this file is at “C:/Windows/System32” so if you open the Task Manager and notice that a process with a similar name has a different location then it is definitely a threat and is exploiting the security of your computer. To resolve issues related to LSASS.exe, here are some fixes that could help.

Option 1 – Use the Performance Monitor’s Active Directory Data Collector

Note that this option will only work on the recent Windows server versions. Refer to the steps below to use the Performance Monitor’s Active Directory Data Collector set on your computer.

• Tap the WINKEY + R button to open the Run dialog box.
• Then type “Perfmon.msc” in the field and hit Enter to open the Performance Monitor and from there open the Server Manager.
• Next, navigate to Diagnostics > Reliability and Performance > Data Collector Sets > System from the left side of the navigation bar.
• Then right-click on “Active Directory Diagnostics” and select Start from the context menu. This will take about 5 minutes or 300 seconds depending on the performance capabilities of your hardware to gather the data required and then take some more time to compile a report from the gathered data. Note that these timings are dependent on one another.
• After the report is compiled, you can find it under Diagnostics > Reliability and Performance > Reports > System > Active Directory Diagnostics. The report will contain all the information as well as conclusions. However, it does not mean that it will also contain the exact cause of the problem with LSASS.exe. Nevertheless, it should help you in fixing the problem.

Option 2 – Try to run the System File Checker

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 to good system files that might be the cause why the LSASS.exe file is having some issues. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

 Now restart your computer and see if the problem is fixed or not.
