Fixing the Machine Check Exception Blue Screen Error in Windows 10

One of the most critical processes in the Windows 10 operating system is the Explorer.exe. And there are times when you might encounter an error that says, “System call failed”. You can encounter this error when you try to launch File Explorer, and in such case when the File Explorer does not work, it could cause issues in accessing folders and files on your computer. This kind of error pops up when the explorer.exe system file has become corrupted or if there is some process that interferes with its smooth functioning. To fix this error, you can try to restart the explorer.exe process, run both the System File Checker scan and DISM tool. You could also put your computer in a Clean Boot State or uninstall any programs you’ve installed recently. For more details, follow each one of the given suggestions below.

Option 1 – Try to restart the Explorer.exe process

The first thing you can do is try to restart the Explorer.exe process. To do so, refer to these steps:

• First, right-click on the Taskbar and select the Task Manager.
• Next, expand the Task Manager window to see all the active processes.
• From there, look for the Windows Explorer process, right-click on it and select Restart.
• After that, check if the error is now fixed.

Option 2 – Run System File Checker scan

If restarting the explorer.exe process didn’t work, you can also try running the System File Checker or SFC scan to fix the error. 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 this command: sfc /SCANFILE=c:windowsexplorer.exe

Note: If you are using a 64-bit Windows operating system, enter the “sfc /SCANFILE=C:WindowsSysWow64explorer.exe” command instead.

• Wait until the process is completed and then restart your computer.

Option 3 – Run the DISM tool

You might also want to run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “System call failed” error. To repair these corrupted system files, you can run the DISM commands:

• 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 and check if the problem is now fixed.

Option 4 – Try running the Check Disk utility

• In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
• After opening Command Prompt, type this command and tap Enter: chkdsk c: /f /r
• The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
• Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 5 – Put your computer in a Clean Boot State

As pointed out, there are some instances that some conflicting programs installed in your computer might be the one that triggers the “System call failed” error to appear when you try to open File Explorer. To identify which program is causing the problem, you need to put your computer in 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.)
• Once your computer has restarted in a Clean Boot State, perform your scan again and see if it now works, and then start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 6 – Try to uninstall the programs you’ve installed recently

In case you don’t know, freeware software packages aren’t always free as some of them could contain malicious software that can cause serious damage to your computer. Thus, if you have installed a program recently prior to getting the “System call failed” error, then you have to uninstall that program.

• Tap the Win + R keys to open the Run dialog box.
• Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.

• After that, look for the problematic program and right-click on it, and then select Uninstall.
• Once the process is done, restart your computer and see if the error is fixed.

Today most users have an SSD drive, times have changed and SSD has become your typical computer equipment. A lot of time has passed from the first SSD hard drives up to today and technology has evolved and improved but still, there are some cool tricks and tips to speed up and extend the lifespan of your SSD hard drive. That being said let us dive right into what I would like to call the essentials of having an SSD hard drive.

1. Keep your SSD firmware up to date.

   This one really is a no-brainer, keeping your firmware updated at all times will ensure longer life and SSD stability. The trick here is that each SSD manufacturer has its own ways of updating firmware so this is not something universal, you will have to go to the official website of your SSD manufacturer and get firmware updates and instructions from them directly.

2. Enable ACHI.

   Advanced controller host interface or short ACHI is a feature that will ensure that your Windows will support all of the features that come with running SSD on your computer. It controls the TRIM feature which is crucial in helping Windows itself in its garbage collection on your hard drive. In order to enable ACHI, you will have to do it from your BIOS and it would be very good if the feature is enabled before Windows itself is installed so it can take full advantage of it.

3. Enable TRIM.

   TRIM feature is vital in extending your SSD lifespan and it should be enabled by default in Windows but you can never be too cautious and double-check and enable if needed. To make sure it is enabled, open your command prompt and type in: fsutil behavior set disabledeletenotify 0

4. Make sure your system restore is enabled.

   In the first SSD days, system restore was really a feature that you wanted to be disabled in order to prevent and extend the life span of your SSD drive, but we came a long way from there and today there is no reason to keep this feature turned off since it can be helping many ways with both your system and SSD.

5. Disable Indexing in Windows.

   A large portion of the speed of your SSD drive is used for indexing files in Windows. Of course, the indexing feature is great if you store everything on your SSD drive but if by any chance you have another drive for your backup, pictures, music, etc. it would be highly beneficial for you to turn it off on your SSD. To turn indexing off click on your start menu, click on the computer. Right-click on your SSD and then click on properties. De-select box that says: Allow files to have contents indexed in addition to file properties and click OK. Once you do this the operating system will apply this to all the files and folders on the drive. If you see a dialog telling you that it couldn’t remove a file from the index, click Ignore All.

6. Keep Windows defrag ON.

   This also was the option in early SSD days which was better to be OFF, but as said before since technology has been making progress and Windows has been improved and made aware of SSD drives, defrag has evolved as well, and now it is more of optimization tool then defragmenter which was once.

7. Disable Prefetch and Superfetch.

   Windows is placing information in both physical and virtual memory for applications that you are not currently using but they are used often in order to speed their response time. If you are running low on space or having struggles with virtual memory it would be best to turn them both off. Go to registry manager and find: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters, there you have 2 values: EnablePrefetcher and EnableSuperfetch, set both values to 0.

8. Disable Search and Superfetch services.

   Disabling Superfetch in the registry is not all work, Press WINDOWS + R to bring run dialog, type in it services.msc, Find both Search and Superfetch and disable them.

9. Configure Write Caching.

   Write caching can be enabled and disabled in the device manager by expanding disk drives, right-clicking on SSD, then click properties, select the policies tab. In the tab, there is the option to Enable write caching on the device. Now trick in this is that you will need to try and benchmark your SSD with both options turned ON and OFF since different manufacturers have different performances with this option being ON or OFF.

10. Disable CleanPageFileAtShutdown and LargeSystemCache.

    Page file and a large cache of page files are not something that we longer need, since SSD writes with great speed in its flash memory both of these options can be disabled and you will both speed up shut down the process of your system and save some SSD life since page files will not be written. Find both options in the registry under the key: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management set both to 0

11. Set high performance in Power options.

    This option in power management will prevent your SSD from constantly shutting down and bringing it up increasing speed without sacrificing its life span.

These are tips and tricks for having great and longer life as well as speed for your SSD drive. We hope that you have found them useful and that you will come again to check new articles published daily for easier IT life.

Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection. However, no matter how great the features are, there a few times when they bring in some bugs too. One of these bugs won’t allow you to either remove or reinstall the Bluetooth mouse and keyboard device from your Windows 10 computer. So if you are currently experiencing this problem, read on as this post will guide you in fixing it. Before you go over the suggestions laid out below, you need to create a System Restore Point first since, in one of the options, you will be making some changes with the registry files as well as some critical Windows settings. Once you have that covered, refer to the following options.

• 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 reinstall or remove the Bluetooth mouse and keyboard devices again.

If you encounter the “We couldn’t install some updates because the PC was turned off” while trying to run Windows Update on your Windows 10 computer, then read on as this post will give you a couple of suggestions you can use as a reference to fix this error. Make sure to follow the options given below carefully.

Option 1 – Perform basic computer troubleshooting

If you get the “We couldn’t install some updates because the PC was turned off” error on your laptop, then it’s recommended that you connect your laptop to a power source and then try clicking the Update button again. In addition, you also have to make sure that your computer stays awake until the Windows Update process is completed. This will ensure that your computer does not go into an idle state and interfere with the process.

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 and then try to run Windows Update once more.

Option 3 – Try restarting the Windows Update Services

• Open the Services Manager.
• From there, make sure that you set the following services and Startup types:
  • Background Intelligent Transfer Service: Manual
  • Cryptographic Service: Automatic
  • Windows Update Service: Manual (Triggered)

Option 4 – 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 5 – Try to install the Windows Updates manually

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

If you suddenly receive an error message that says, “The selected boot device failed, Press <Enter> to Continue” during an installation on your Windows 10 computer, you should know that this kind of error can occur when you use a USB stick as well as a DVD Disk to boot from. This error indicates that some settings inside your BIOS are not compatible with the bootable device that you have created. Note that fixing this kind of error does not vary from device to device at all. All you have to do is change some settings in the BIOS and create a proper bootable disk. Follow the options given below to fix the “The selected boot device failed, Press <Enter> to Continue” error. The options below do not have to be necessarily followed in the same sequence since you can create a bootable USB drive before you change some settings in the BIOS.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further Options including System Restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows 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.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.

As you know, any software needs sufficient CPU power when it downloads, updates and installs so if you encounter an error code 0x80200070 when you tried to install or update the Microsoft Edge browser on your Windows 10 computer, then read on as this post will guide you on how to fix it. This kind of error occurs when the Edge browser installation does not get enough CPU power to update or install and the only way to fix it is to kill programs that are consuming a lot of PC resources as well as stop or remove any unnecessary programs that are running in the background. This kind of error can also be encountered in the new Microsoft Edge Chromium. For more details, follow each one of the options provided below.

Option 1 – Try to kill applications that consume high resources

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Go to the Performance tab and sort by CPU usage.
• Next, close a few additional programs that are consuming maximum CPU power.
• After that, try to update or install Microsoft Edge again and check if the error is fixed. If not, try to restart your computer and then start the installation or update again.

Option 2 – Try to remove or stop unnecessary programs and services

If the applications or processes that are consuming a lot of CPU resources reappear even after you kill them or end their processes, then you can try the following suggestions to remove or stop these unnecessary programs and processes.

• The first thing you can do is to stop the Service. If the program happens to be a service, then you have the option to disable the Windows Service. All you have to do is open the Services Manager and stop the service. How? Refer to these steps:
  • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and tap Enter to open the Services Manager.

• After that, identify which service is consuming a lot of power and then stop it temporarily.
• The next thing you can do is to uninstall the problematic program. If the one that consumes a lot of resources is not a service but a program, then you can try to uninstall the program for the meantime until you’ve updated or installed the Edge browser. Once you’ve uninstalled the program, try to update or install Edge again.
• You can also try booting your computer into Safe Mode and then update or install Microsoft Edge. This will make sure that all the unnecessary programs and services won’t consume a lot of CPU resources as well as memory.

Windows 11 has come a long way from its infant stage. Today it is incredibly good and stable operating system that also looks good and modern. Unfortunately, fancy animations and good graphics come with a price, in this case, slower performance on some little older and weaker computers.

Animations itself which include also fading effects can sometimes feel slugging and laggy and have a general overall feeling of delay. For a more old-school instant experience, you can turn off animations.

In order to turn animations inside Windows 11 follow this simple guide:

First thing is to open Settings by pressing Windows + i key combination or you could open Start and in the search box type in Settings and then click on its icon.

Once inside settings on the left side find Accessibility and click on it to select it. Once it is selected on the right side choose Visual effects. Inside the visual effects section click on the switch next to Animation effects to OFF. You can also turn off transparency effects in this section if you wish if you have an older GPU in order to speed it up a little.

That is all you need to do, settings will be automatically saved and all animations will be turned off for a quicker and more responsive feeling when working inside W11

Error 0x80070780 is a particularly nasty error since it means we can not access files on our hard drive. This might be an important file from work or anything similar and it can be frustrating when we can access it. In this article, we will address solutions to this error so you can continue with your activities where you have left off. Follow the guide step by step in the given order to minimize file damage and find the solution quickly.

1. Run File and Folder built-in troubleshooter

   The simple and clean solution, try first by running Windows built-in tools. Leave troubleshooter to scan and attempt repairs and try to access a file after that.

2. Run disk checker

   Maybe the file is corrupted or slightly damaged but repairable, run a built-in Windows disk checker and let it scan and repair any error found. Try accessing your file after the scan.

3. Try copying file

   If the file is under a bad sector or cluster on a disk drive that could be a reason why you can not access it, try copying the file to another location and then opening it, if the operation fails, boot Windows in safe mode and try to copy or move file then. If you are successful with copying files in safe mode, reboot your computer and try to open the file.

4. Reinstall the driver for the hard drive

   Like when the driver for USB is not working and you can not access files same can happen on your hard drive. Go to the device manager and reinstall the driver for your hard drive.
